Budapest Danube River Boat Tour by Hop On Hop Off City Sightseeing

When we were in Budapest, we used Budapest Danube River Boat Cruise by Hop On Hop Off by City Sightseeing to explore the river. It was easy, affordable and fun!
As we used the 2 days Hop On Hop Off City Sightseeing, we also get this 2 free days of using the boat.
From the river we could see the landmark of the city such as The Parliament building and the Buda Castle.
So when you are in Budapest, don't forget to enjoy the city from Danube River using the boat!
