Tresviso Caves Project - Road to Certain Death - Cave Diving
Operating from the mountain village of Tresviso (Cantabria), in the eastern massif of the Picos de Europa, the current expedition team has been mapping and exploring caves in the area since 2015. However cave exploration here has been taking place since the early 1970’s when Lancaster University Speleological Society (LUSS) first visited the area.
Tresviso is situated above the Urdon gorge where a major cave, Cueva del Nacimiento (also known as Cueva del agua) resurges. The water which leaves the cave is captured by the Canal de Urdón which takes it to the nearby hydroelectric station. Each day millions of litres of water flow out of the cave which is indication of how significant it is for the hydrology of the limestone mountains which tower above the gorge.
In 1976 the cavers exploring Nacimiento located an unusual feature. After Colin Boothroyd scaled an 8m waterfall they found a deep sump pool immediately at the top of the climb. Inspired by Monty Python they named the cave passage the ‘road to certain death’ and the sump itself became ‘certain death’.
Rob Parker was first to venture into the water in 1985 and again in 1986 when he reached -64m and reported an ascending shaft leading on. Gavin Newman then took up the challenge of diving here which culminated in the 1996 trip where he made a film for the BBC’s extreme lives series about diving the sump with Phil Short. The film was called ‘the road to certain death’ and features Gavin, Phil, Colin, Jim Thompson and Mark(?)
Since 1996 the sump has remained dived until this year when I was able to make an attempt to explore it thanks to an excellent team of cavers from the Tresviso Caves Project. The sump is located approximate 1 hour from the entrance but before I could dive we needed to re-climb the 7m water fall and rig ropes in this section. Then the heavy and bulky diving equipment was carried to the sump for me to dive. I was expecting a deep dive with significant decompression and chose to use a KISS Sidewinder with TMx bailout/dil. At the furthest point reached by the previous explorers the way on was clear to me, a tall rift which opened out quickly into a huge passage. After 200m of diving and route finding the passage had ascended to 6m depth where after completing my final deco stop I was able to surface in a medium sized lake. Following the cave upstream I soon encountered sump 2 which I passed after a 40m dive to reach a sizable dry chamber with several possibilities for future exploration.
A massive thanks to all the cavers on the Tresviso Caves Project expedition who made this possible and to the previous explorers of this fantastic cave.

The summer of 2020 presented me with another opportunity to carry out a deep dive at Wookey Hole. Whilst everything didn't go to plan I was still able to capture some video footage on my Paralenz camera. I've put this together with a narration of the dive so that others can see what this bit of cave is like.

Man this is a tight space fit in.
Hi! Peter Laws here, from the Frightful channel. I'm considering doing a TH-cam video on Wookey Hole and wondered if it might be possible to feature some of your footage in the video. I would of course offer full credit both on screen and in the video description. I'd also include a link to your channel, and this video, to drive more traffic your way. If you're interested, let me know. But no worries if not. Thanks!
Hi Chris...I just realised that this video is marked as Creative Commons reuse! That's great. I missed this before, so will use clips and attribute your channel. Thank yoU!
Hi Chris, absolutely love your videos. I hope you don’t mind me asking…are you the one of the legends from the Thai cave rescue ? Your name rings a bell. All the best mate from 🏴
I was at wookey today. From Canada. Just amazing. No diving just touring.
Astonishing! Just being curious about what rebreather did you use? Homebuilt?
Love the way you shot this!!
Chris, Do you worry about air quality in the dry passages? Is that ever an issue?
You had some harsh moments coming out through that restriction. I'm glad that you were able to finish your dive sound and healthy. Thanks for sharing
Brings back memories of 1982. Dived all seven remnants of the german high seas fleet in one week. Not bad in a 7mm wetsuit and a 96cu ft bottle.
Hi Chris. Are you still using this 13 years later? How do you control your O2? I'm guessing you monitor on the computer and exhale through your nose when it gets low? What depth have you taken this to? Many thanks for the great content on your channel
How do younfit your massive set of bollocks through there? FML that looks terrifying and incredible in equal measures
RIP Artur
ytho
how would you donate air to a buddy with regs clipped off with carabiners, i assume primary donate, but im interested to hear how you worked around the awkward faff i find carabiners to be
Ok I kinda understand the how and why . My question is in case of put of are you just give them a complet tank . Rather than going with a longhose? Looks neat and functional.
What size bottles are those?
A boulder choke in a dry cave is fine, doesn't bother me, I go through them all the time. But 70m under water with full diving kit on and 2.5 hours into the dive? Mental
Thanks for sharing, respect
Nice video 💯
is it cave diving in 2020, really?
That's the beauty of SM configuration, capabilities to adapt "personal mods". Loved it
I really like your set up. It's helped me to overcome a few issues, I have had. Hose lengths And mounted carabiner makes life so much easier
This made me nervous..glad you made it dude but if its that tight dont bother with a route, find another...
Man you must have been one of the last people to get one.
Amazing shots! New subscriber here, you're almost 1k! All the best!
Hey mate, what did you use for the head/interfacing the o2 cells with the computer?
Digging your way through a cave with your tanks disconnected. fair play
😍 𝔭𝔯𝔬𝔪𝔬𝔰𝔪
Good Luck with the project. Aren't you pushing depths of diving on air and depths at which decompression is needed? It's be a great idea to include some basic safety notes I'm sure you have some more footage you could plany in the background. Caving disasters are problematic for all who do it. First, that caving should be left to those certified to do it. We had xxxx tanks for xx mins of diving and planned dive time of xx mins, allowing for deompresion, getting out of easy issues like cave silt blackout.... 2. This is a very dangerous cave due to its' inaccesiblity making any hope of rescure all but impossible, it beind a xx hr climb through a running stream. 3. Always use guide lines never letting go, EVER.
On the other hand, giving out specific details for cylinders used and dive plans could inspire others to emulate Chris' dives, as it worked for him so it must work for them right?
This was so fascinating and beautiful!!
Hello Chris, thanks for the video. Was wondering if using an old reel of rope and going into the unknown was a worry for you? (line deteriorated) Or those don't deteriorate with time? Sorry if the question is stupid, I'm not a cave diver.
Awesome - I still have the film Road to certain death!
Interesting video Chris, who's the master magician 1.29seconds in? - impressive 🙂
Thanks for sharing!
Wow!
Absolutely amazing and well done!
WHY is the risk of this cave worth it?
If you have to ask then you will never figure out the answer
How deep is it?
Most of the diving is between 35m and 42m or so. I think it was cruisers shown so likely 35 ish.
The 3 battleship/battlecruisers are in 50m of water
Great video as always Chris. Really like the camera, great footage.
Reasonable challenge I love it.. great video loved the interviews 👍
Hello Chris, love your videos. Can you give us info to make this DIY spools? Thanks a lot
I notice you wrap bungees around the tap rather than the post. Tell me about your experience with that.
What's the music mate? Amazing dive.
Greatest respect to you, I have done a small amount of cave diving in the past but nothing like this.
Welcome to my home !
Dude carabiner clips why not bolt snaps? Cave diver
There is an old submerged Mine near to where i live in North Yorkshire, always wanted to see beyond the water line.
How does Chris not have lots more Subs? Caving and the Diving involved are super complex, it really takes a certain type of person to live in the moment and make correct decisions under the most pressure literal and mental is incredible. I have huge respect for these lads.
Excellent video in every place that didn’t have that damn background noise I’m sure, you call music!!!! All music sucks!! In diving videos!!!!!!
Much better with voiceover instead of music 👍 thank you and great work
