That's the best bit of cave exploring footage I've ever seen. So many videos are "mistake" videos or "death" videos or "dumbass crawls headfirst into a tiny hole and ends up upside down with about a thousand people called in to rescue him" videos. Good to see one with decent size caves, repels down, climbs up, water, dry bits and new mapping. Enjoyed that one.
@@LukasEddy I watch it just for the heart-attack factor. But such an expedition is worth more than 7 minutes, right? I hope there is more. Thanks for this.
Very cool. Reverse mountain climbing has always been an interest to this old spelunker. The bad air must be nitrogen and carbon dioxide from the decaying organic debris, which is seen in the video, even in the lower passages. Harmful gasses are especially concentrating in the dry sections isolated by sumps, and in the lowest, poorest breathing sections of the cave. I would be careful using a lighter as a testing device. Methane could be present, methane being a highly flammable gas also produced in the process of the decay of organic matter. I am so pleased this dangerous expedition produced no extreme drama and all returned safely to the surface, a credit to your planning. Kudos to that small Italian team as well. Were there even LED lamps and lithium batteries 30 years ago? I remember when we used acetylene miners' lamps in the late 1960's.
You folks are very brave, I can't imagine being in a small space that you aren't sure you are going to be able to get out of. Be safe, thank you for sharing your adventure.!
There's a strange amount of hateful people in this comment section. I think they're not particularly interested in caving... Just algorithmic expatriats
I like the fact that the locals can still hold on the idea that the cave still holds the giant golden tree. I love the fact that this legend will not be spoiled today.
@@skippylippy547 laugh it up Joy Boy. So you believe the geologists cosmology? No astrophysicist has ever theorised a solid Earth model as its physically imppssible. Simple.as that.

It's the worst feeling. Going through some really crazy stuff only to see a name scrawled on the wall, or a bolt set like yall found. Ok, not the worst feeling. It definitely leaves you with a sense of wonder at what the people who were there before you had to go through with even less technology than you had. Hoping yall have more adventures to come with yall being the first ones ever inside plenty more caves!
It's true. Documentation of what cave exploration has already been done is too often hidden, and 'exploration' is repeated! But yes, the previous generation of cave explorers was certainly amazing, doing so much hardcore caving with such poor technology.
Trying to badmouth the Italian explorers who went there first is bad form... You can't just reject their contribution by saying they might have falsified their information. A simple reference to their names wouldn't harm either: Giuseppe Muscio and Umberto Sello. It's condescending on your part, to say the least.
Most youngsters jump into the vehicle's blissfully unaware of 4 wheel driving,High and low gears and dif lock? Just slam it into four wheel drive and "floor it" digging themselves in
the level of planning and skill to pull off these adventures somewhat safely is insane. kudos to you guys for pushing the boundary of human exploration in the 21st century.
Thank you! There is a lot of behind-the-scenes work for cave expeditions - I'd estimate each minute in-cave has an hour of prepartion in the form of permits, transport, camp duties, local connects, etc.
I was only going to comment: I't might be as well, the cave system remain unexplored to the very end. That way the theory of the golden palm can live on. But reading through some of the comments I was surprised of so much negativity. Not fun to get that response. Guess there's easier being a keyboard warrior then actually doing things like this expedition.
Muchísimas gracias por excelente video 🇩🇴🤩✨ I'm from Dominican Republic and my family lived for a long time in the nearby city of Las Matas de Farfán, never to the cave but I've been told many times about the legends and curiosities of the cave, what a great effort of yours producing an accurate map. I hope that one day, the Dominican authorities make a similar effort and produce maps and information about the caves publically available. Thanks so much and I'm glad you had a great time in my country.
Hi Daniel, thanks for the support! To my knowledge, the Dominican Government has rules to keep cave locations secret. This type of rule/law is common in many countries, including the US, as it protects the caves. Once locations are publicly known, people will go and vandalize the caves. The Dominican Government also has an interest in developing more caves for tourism, which ruins caves. They sent a representative to this cave to speak with us, but we explained it's so deep, and so prone to flooding, with unstable rocks, that any sort of tourism would eventually result in a fatal disaster. Otherwise, I am not aware of any Dominican caving groups that set out to explore and map deep caves like this one - although I think it would be a great idea!
What a cool video! The TH-cam algorithm pointed me to this and I really enjoyed it! You’ve got a new subscriber! Funny, as an avid outdoorsman, this is the only sport that truly creeps me out. I’ve summited mountains, spear fished around sharks, rock climbed, mountain biked, cliff jumped, sky dived. All in various cycles of my life’s adventures and hobbies. But this? Whew…. You guys are a special breed!
Caving is fascinating and horrifying. This cave looks to be one of the most dangerous possible . Heights and tight squeezes are 2 things that really scare me. My uncle is an accomplished caver in the southwest , he has been places no other humans but him and his wife have seen. He even discovered a previously unknown extinct bat . I dont think id be able to do that mentally. So much can go wrong so easily and youll never be found.
@@LukasEddy a lot of it seems to be dont panic dont be stupid . Not alot scares me except heights and tight squeezes. I've definitely panicked on both of those b4.

A full hour crawl in and out for the 8 Nope. slimy, fungus and ...nope. A whole bag full of nope. I've gone caving , but in Eastern Washington. We see dry caves. I love that 10 foot down in the summer, those caves that go deeper are soo cool. literally. any hoo, even though my own heeebi geeebis come in to play, Love this video! keep your head down!
I appreciate the video and knowledge. Obviously I will never venture into such a place. So you and your friends exploring are our view of such places and I thank you for that. Just be careful and watch for dead air situations. By the way, when I was younger, I too explored caves with others...
Exploring caves, something I would love to do, but will probably never get too deep into. Two reasons; I'm too big and to be honest, I don't think I could handle the constant dark and tight spaces not knowing what's beyond. For now I'll have to stick to show caves and the one time I did a spelunking tour at Wind Cave in the Black Hills. Kudos to those who do this.
Very cool exploratiion! Thanks for sharing! Excellent mapping work! I'd love to know more about your mapping techniques. I used to be a surveyor but we never mapped any caves. cheers!
Thanks! We use a laser device, called a Disto x2, that maps azimuth, inclination and distance, and then plot the shots on paper in-cave and then manually sketch the features and passage shape, which we then scan onto a computer program to edit to make a digital map. Making the maps for this cave took me about 40 hours on the computer.
@@LukasEddy Thank you so much for sharimng! We used to used a robotic total station... very expensive cool device for doing basically the same.. except al digitial collection A-Z. cheers! Here's a quick video i found for visual refernce if you're interested. Cheers!
You guys should have considered adding a miniature drone with your equipment to further explore areas that you found too risky to enter. Even though you may not have received much more data from it, that little bit would have been a great advantage. At least you would have had glimpses of parts that were inaccessible by the Italians.
We did take a drone. The problem was that as soon as you fly the drone past a bend in a cave, it loses all contact with the remote, and won’t function. Better technology in future years may help!
You should always take a green laser pointer in that shows the beam so you can look further then you flashlight allows, won’t be a bright light but it will show the continuous beam through passageways
It gets washed in during rains. There are plenty of rats and livestock in and around the entrance. Cows have even fallen into the 500-drop at the entrance, and decomposed inside!
I had a friend who got into diving, then into rescue diving and then into cave diving. When he wasn't diving, he decided to do the cave exploration on land and got into spelunking. Me... I will never ever understand the mentality it takes to do that. I could probably do regular diving, but never into a cave....ditto with any cave, below or above water. I just have a deep fear of dying, trapped in a dark place, pinned and unable to move, due to something like not being able to get through a small tunnel, or a rock shifted and pins ya, or in the case of cave diving...getting an air hose snagged/ripped and not being able to surface. I think I would rather be burned alive than trapped like that, or say in the rubble of a building after an earthquake, just not being able to move, and just having to lay there and endure that until I die. My friend couldn't explain to me why he found it fun, and challenging...even when he tried to tell me about all the wonderful things he saw that maybe less than 100 to even a few 100 people in the history of the world got to see, to experience. And yes, even the thrill of finally getting out and breathing fresh air and feeling the sun on one's face or seeing the moon up in the sky...he said it just makes a person feel more alive. Still... I'll pass. I find it interesting what ya all are doing, but I also think you are all a wee bit crazy to be doing it. :P
Wow! Right next door to me. I'm a caver too here in Haiti. I live in Port-a-Piment that has the longest mapped cave in Haiti, the Grotte Marie-Jeanne. I've led several cave exploration expeditions with multi-disciplinary teams from the US (University of Kentucky) see NSS newsletter January 2014 dedicated to caving in Haiti. On one of our expeditions we came across a deep vertical cave but did not have enough rope with us to make the descent. I took a couple of photos of the entrance I could send you. The cave looks really promising and no one has ever been down it. If you're interested in verticals let me know.
A full-blown waterfall a little further down and a huge pocket of bad air. One day somebody's going to find what everybody calls Agartha. What's a daydream without imagining an advanced people that went 16 to 18 miles down. To get away from the Savages above start a new life.
They went down to escape the global fires from meteor bombardment or coronal mass ejection about 12,000 years ago according to Göbekli Tepe. Our Caveman ancestors claim people came out of the earth and seas to teach them culture, technology and langauge. The first Vault Dwellers.
Enjoyed this video. I used to explore caves when I was a lot younger and much more pliable. Doing this was a lot of fun and I wish I was able to take my kids, and now my grandkids, into some of the caves I once explored. Not to be. The land owners no longer allow it due to liability issues.
One thing bothers me - you say you couldnt find the river, and perhaps it was the wrong time of year. I've seen so many videos of cavers drowned, just from a thunderstorm. What kind of research did you do before going down, and how did you know you wouldn't be trapped by a flood?
Hopefully! For now, we can't fly drones in caves because they lose service once they pass a bend in the passage. In the future, hopefully there will be other ways.
Caving is incredibly fun and nothing in life is safe. But still cant bring myself to enter any caves with the possibility to flash flood, yall are brave af
1:39 That is precisely why you should have your own off-road vehicles, instead of trusting a rental company to actually do maintenance on their vehicles.
By the time that cave is fully explored and we are all dead, people from the future will come back to this video and try to understand why there's so much negativity in this comment section. They will probably fail just like I did lol
Better you than me. I am impressed by your mapping technology, though. I've studied GIS, and I'm somewhat familiar with mapping above ground. How do you get such nice maps underground?
Thanks! We use a laser distance device (called a Disto x2) that also measures inclination and azimuth, and use it to create a line plot in-cave, with manual paper-and-pencil sketching overlay. This data is then translated via computer software to produce a final map. It's a very long and arduous process for the final map.
@@LukasEddy That's very interesting. I'm just getting into real estate photography, which introduced me to measurement certification and tools that I didn't know existed until this last year. I've seen devices similar to the Disto x2, but now I see that using that name in a Web search brings up a lot of references to cave and archeological mapping. I've had a daydream for several decades of creating virtual spaces mapped from the real world, specifically a driving simulator. I would like to be able to recreate real places digitally. My processes still are crude, so I appreciate information for improving them.
@@Pooua Very cool. There are a range of survey devices, but it's still difficult to translate the data to many mapping applications. The newer iPhone models do have Lidar apps, which may help you with digital scan of small spaces like houses etc. For driving... I wouldn't know, unfortunately.
Dominican here, there's nothing but filthy water in that cave, and nobody here cared enough to map it. However you can visit other caves that feature better tourist attractions like the "three eyes" cavern
Catanamatias es la cueva mas profunda del pais. Es por eso que nos interesaba. No se habia mapeado ya que el aceso es dificil, y se reuiere un buen de cuerda y equipo. No nos interesaba cuevas turisticas, sino nos interesaba la exploracion.
Yes interesting array of comments!!. If for nothing else im glad i watched it to know im def not a muddy cave lover!. But have respect for the skills, much like mountaineering etc....which i have equally no wish to do!😄
@@R3TR0R4V3 I don’t know man, I think the occasional beeping is their camera or lights. I have never once heard them reference having an air monitor. I’m not saying they couldn’t, but my little daughter and I watch most of their videos and I can’t recall them ever referencing one.
Our bodies - increased respirations, headaches, tachycardia - and a lighter. This is standard caving practice in much of the world. Bad air in caves is not like in mines, eg flammable. It’s typically simply high CO2, as in this cave.
Cost Rica has experienced extreme drought in 2019 and again in 2023 and it's even worse in 2024. So no rushing river. I'm sure if you waited around for a hurricane you'd get that river you were looking for, complete with a waterfall right at the entrance.
personally i am afraid of dark, deep, narrrow places like caves and may never venture inside (depends if i get a opportunity then what i will do) but thanks for people like you to show the hidden world
We have no plans to return. With better respirator technology, another group may eventually unlocks the secrets of this cave. I suspect MILES more of passage.
Hi, I explored a few caves in the Dominican Republic back in the 90s while I was working there. I found one with ancient Caribe paintings, mostly of animals etc. I was told it was probably an ancient spirit cave where locals would visit the spirits of their ancestors. After I had a good look around and took some photos the government gated the entrance to prevent anyone else going in. It was quite a small entrance, about 50cm across and quite steep. To make sure I could get back out up the slippery slope I put a bolt in at the top of the steep section. That probably gave whoever eventually went in to record it a wtf moment, thinking they were in a previously unexplored cave.
I have absolute total respect for you guys. I couldn’t do anything like this. I got stuck in a drainage pipe, about 12-14”, when I was 9-10 years old. Now I don’t even like going into a closet 😂
Thank you for sharing this amazing video. Question: did you stay in the cave system for several days straight (taking care of bathrooms and food during the expedition) or did you go back and forth to base camp?
We didn't stay inside. It's around two hours travel time from the bottom to the entrance, so we didn't think it would be worth it to haul in camping equipment and food to spend a night. Base camp was a 25-minute walk from the entrance.
This video got me super excited about never going into a cave. Stoked bro.
It's a lot of fun!
😂
100% stoked as well to never ever.
A lot of adventure shown to us in less than 8 minutes. Nice work and thanks for sharing!
That's the best bit of cave exploring footage I've ever seen. So many videos are "mistake" videos or "death" videos or "dumbass crawls headfirst into a tiny hole and ends up upside down with about a thousand people called in to rescue him" videos. Good to see one with decent size caves, repels down, climbs up, water, dry bits and new mapping.
Enjoyed that one.
Thanks! We don't risk death for caves - better to emerge alive.
@@LukasEddy I watch it just for the heart-attack factor. But such an expedition is worth more than 7 minutes, right? I hope there is more. Thanks for this.

Thanks for watching, glad you enjoyed it!
Ahhh... a Jeep in it's natural form:
Broken down, on the side of a trail.
True.
Wow! Right next door to me. I'm a caver too here in Haiti. I live in Port-a-Piment that has the longest mapped cave in Haiti, the Grotte Marie-Jeanne. I've led several cave exploration expeditions with multi-disciplinary teams from the US (University of Kentucky) see NSS newsletter January 2014 dedicated to caving in Haiti. On one of our expeditions we came across a deep vertical cave but did not have enough rope with us to make the descent. I took a couple of photos of the entrance I could send you. The cave looks really promising and no one has ever been down it. If you're interested in verticals let me know.
We would LOVE to come caving in Haiti. When it's safer, of course :)
That's incredible. It's great fun as long as you all make it out. Sorry for the spelunker who was hospitalized.
Thanks! We had a blast.
Thank you for this video, I could never !! Fascinating video, stay safe. ❤❤
Change in elevation caused wrong Mapp sensor reading to computer. Disconnect battery ground to battery for a few seconds, reconnect and try again.
I've heard about a whole bunch of caving disasters, but if I'm being honest, leptosporosis was not on my list 😂
everytime i see stagnant cave water all I think is damn this shit's gonna give these guys leptospirosis
It's uncommon. Good hygiene and not entering water with open cuts reduce the risk.
1st mistake was driving a jeep on that road. Should've driven a toyota.
It’s true. Jeeps are just not dependable, and failed us big on this expedition.
@@LukasEddy since they were bought out by Chrysler, I call them Cheeps.
Errrt
True.
Land Cruiser
What an amazing and so well planned explore indeed.
Thanks! Dark and beautiful!
A full-blown waterfall a little further down and a huge pocket of bad air. One day somebody's going to find what everybody calls Agartha. What's a daydream without imagining an advanced people that went 16 to 18 miles down. To get away from the Savages above start a new life.
They went down to escape the global fires from meteor bombardment or coronal mass ejection about 12,000 years ago according to Göbekli Tepe. Our Caveman ancestors claim people came out of the earth and seas to teach them culture, technology and langauge. The first Vault Dwellers.
Enjoyed this video. I used to explore caves when I was a lot younger and much more pliable. Doing this was a lot of fun and I wish I was able to take my kids, and now my grandkids, into some of the caves I once explored. Not to be. The land owners no longer allow it due to liability issues.
A valid concern with caves everywhere. Caves on public land, such as national forest land, are sometimes more accessible.
One thing bothers me - you say you couldnt find the river, and perhaps it was the wrong time of year. I've seen so many videos of cavers drowned, just from a thunderstorm. What kind of research did you do before going down, and how did you know you wouldn't be trapped by a flood?
We went in the dry season (January) and checked daily weather forecasts. In the wet season, the whole cave floods and is deadly.
There are less and less of truly interesting posts on youtube except this. I really enjoyed this radical adventure/ science presentation.
Yes indeed. It was soooooooo radical! 😂
As a jeep wrangler owner I can say Honestly it's the most unreliable vehicle I've ever owned
Agree.
Shouldve gotten a 80s/90s cherokee xj lol.
This is so wonderful, Lukas! Kudos to you and your team, and thank you for sharing. :)
Thank you for watching, Johanna. A big, scary, amazing cave :)
that waterfall was probably the river the Italians couldn't pass
Could be!
im almost 3 mins in before they head in and bro that goose has me dying. their guide is a kind soul. thank you for being you.
The goose was named Rocha. It was aggressive with everyone but Negrito!
For adventure with people it may be another 30yrs but for pure exploration and mapping it may only be 5-10yrs with drones.
Hopefully! For now, we can't fly drones in caves because they lose service once they pass a bend in the passage. In the future, hopefully there will be other ways.
Fully automated drones that can fly without manual control. Only problem is the battery life.
That would be awesome! @@gavinlew8273
Is there a phobia about going into a cave and being trapped there? If so then I have it.
Same
Yes, even cavers can have a phobia like this. We mitigate it through training and experience, but still remain cognizant of many dangers.
Caving is incredibly fun and nothing in life is safe. But still cant bring myself to enter any caves with the possibility to flash flood, yall are brave af
To mitigate flash flood risk, we went in the dry season, and checked weather forecasts daily. In the wet season, this cave would be quite deadly!
Brave you all are. Never a caver. Stay safe. 👍👍
WOW!THANKSFOR SHARING!ICOULDN,TDO THAT!
Its crazy that down in a cave that isnt a mine has contaminated water and bad air.
holy crap, this is awesome work! I hope your channel blows up in popularity!
That road is an above average mountain road in Colorado, and it is clearly heavily trafficked based on the lack of overgrowth.
1:39 That is precisely why you should have your own off-road vehicles, instead of trusting a rental company to actually do maintenance on their vehicles.
True, but we don't live in the DR. My vehicle is in the US.
By the time that cave is fully explored and we are all dead, people from the future will come back to this video and try to understand why there's so much negativity in this comment section. They will probably fail just like I did lol
Yep, I don't understand either.
Those Italians were incredibly skilled cavers to get possibly further 30 years ago then cavers with even more modern gear can today.
Indeed! We were impressed by their exploration skills. Much respect to them!
We always used to say in our caving club that if the Italians had been there, they had done a LOT of it.
@@dawnmoriarty9347 It's true! We have a lot of respect for Italian cavers, as they are very, very skilled.
Better you than me. I am impressed by your mapping technology, though. I've studied GIS, and I'm somewhat familiar with mapping above ground. How do you get such nice maps underground?
Thanks! We use a laser distance device (called a Disto x2) that also measures inclination and azimuth, and use it to create a line plot in-cave, with manual paper-and-pencil sketching overlay. This data is then translated via computer software to produce a final map. It's a very long and arduous process for the final map.
@@LukasEddy That's very interesting. I'm just getting into real estate photography, which introduced me to measurement certification and tools that I didn't know existed until this last year. I've seen devices similar to the Disto x2, but now I see that using that name in a Web search brings up a lot of references to cave and archeological mapping.
I've had a daydream for several decades of creating virtual spaces mapped from the real world, specifically a driving simulator. I would like to be able to recreate real places digitally. My processes still are crude, so I appreciate information for improving them.
@@Pooua Very cool. There are a range of survey devices, but it's still difficult to translate the data to many mapping applications. The newer iPhone models do have Lidar apps, which may help you with digital scan of small spaces like houses etc. For driving... I wouldn't know, unfortunately.
Great content, hope to see more!
More coming, thank you!
Im from dominican republic and never heard of this cave. Anyway, the great lepto bath name had me crying in laugh
Yea, it's not well known, not easy to access, and not easy to enter. Many Dominicans are unaware for these reasons...
Very cool adventure!
Thanks!
Dominican here, there's nothing but filthy water in that cave, and nobody here cared enough to map it. However you can visit other caves that feature better tourist attractions like the "three eyes" cavern
Catanamatias es la cueva mas profunda del pais. Es por eso que nos interesaba. No se habia mapeado ya que el aceso es dificil, y se reuiere un buen de cuerda y equipo. No nos interesaba cuevas turisticas, sino nos interesaba la exploracion.
Yes interesting array of comments!!. If for nothing else im glad i watched it to know im def not a muddy cave lover!. But have respect for the skills, much like mountaineering etc....which i have equally no wish to do!😄
The action adventure twins would like this!
Given the comments on their videos, I'm not sure they would know to test the air quality.
@@SnowDiscGolfThat’s why we want them doing the exploring! They don’t need no stinkin’ air checkerthingys!
The AAT do carry air monitors.. You can hear it beep here & there in their videos.
@@R3TR0R4V3 I don’t know man, I think the occasional beeping is their camera or lights. I have never once heard them reference having an air monitor. I’m not saying they couldn’t, but my little daughter and I watch most of their videos and I can’t recall them ever referencing one.
Did you have a sensor that told you of "bad air"?
Our bodies - increased respirations, headaches, tachycardia - and a lighter. This is standard caving practice in much of the world. Bad air in caves is not like in mines, eg flammable. It’s typically simply high CO2, as in this cave.
Cost Rica has experienced extreme drought in 2019 and again in 2023 and it's even worse in 2024. So no rushing river. I'm sure if you waited around for a hurricane you'd get that river you were looking for, complete with a waterfall right at the entrance.
This is pretty neat. Spelunking is deadly but SO interesting
personally i am afraid of dark, deep, narrrow places like caves and may never venture inside (depends if i get a opportunity then what i will do) but thanks for people like you to show the hidden world
I also hate dry passages, and unbreathable bad air.....but I'm glad you were able to continue! 😉
Are you considering returning for another try in the future or are you settled with leaving it to other teams?
We have no plans to return. With better respirator technology, another group may eventually unlocks the secrets of this cave. I suspect MILES more of passage.
Hi, I explored a few caves in the Dominican Republic back in the 90s while I was working there. I found one with ancient Caribe paintings, mostly of animals etc. I was told it was probably an ancient spirit cave where locals would visit the spirits of their ancestors. After I had a good look around and took some photos the government gated the entrance to prevent anyone else going in. It was quite a small entrance, about 50cm across and quite steep. To make sure I could get back out up the slippery slope I put a bolt in at the top of the steep section. That probably gave whoever eventually went in to record it a wtf moment, thinking they were in a previously unexplored cave.
Those maps make all that struggle worth it
Agreed!
I have absolute total respect for you guys. I couldn’t do anything like this. I got stuck in a drainage pipe, about 12-14”, when I was 9-10 years old. Now I don’t even like going into a closet 😂
Uhm ... I have to ask .... why did you go into a drainage pipe?
Claustrophoia is real. Caving can help us get over it.... or make it worse!
Thank you for sharing this amazing video. Question: did you stay in the cave system for several days straight (taking care of bathrooms and food during the expedition) or did you go back and forth to base camp?
We didn't stay inside. It's around two hours travel time from the bottom to the entrance, so we didn't think it would be worth it to haul in camping equipment and food to spend a night. Base camp was a 25-minute walk from the entrance.
Looks pretty darn good!
It was probably raining or had rained recently. That's how it turns into a raging river.
A return trip with twice the rebreaths? Since im assuming you used stainless bolts and left them?
