Did you know that the longest uninterrupted underground journey in Europe awaits you at the Remouchamps caves?

A true wonder of nature, the "outbound" trip through the Remouchamps caves (in the province of Liège) is done on foot and takes you on a journey of over 1,000 metres through spectacular chambers and galleries. You'll make the 700 m return journey through the lower part of the caves by boat, making it Europe's longest underground journey accessible to tourists!

Once past the entrance, the tour begins in the first hall, inhabited by Palaeolithic hunters 8,000 years ago. The journey continues with a walk through a maze of chambers and galleries, where you'll discover stalagmites and stalactites.

Among the natural gems, you can explore the Grande Draperie, dripping with rainwater. This seven-metre-high room dates back several hundred thousand years. It tells us that all the crystalline deposits that adorn the cave are due to the infiltration of water, falling from the vaults, gliding down the walls and depositing the limestone that makes the caves so beautiful.

You'll then be taken to a room discovered in 1912, known as the Cathedral, which is 40 m high and could easily hold a twelve-storey building. This is where you reach the underground river by crossing a large natural arch, the Bridge of the Titans.

And make sure not to miss the "Palm Tree", a column formed by the joining of a stalactite and a stalagmite. Its curious position in the middle of the Rubicon river is a unique phenomenon. A short distance away, the ceiling drops and the boat enters an ancient siphon, which has been enlarged by humans to make it passable. As you exit the siphon, the passage widens and the daylight becomes brighter.

The caves are more than just a wonder to behold. They also form an entire ecosystem home to several creatures – the most well known of which is likely the bat.
