This route corresponds to stage 4 of the 7holes Challenge, the shortest, but with a very varied profile.

After a beautiful 3km approach to the middle of the Dent plateau, the entrance opens up to us in the ground: this is our entry shaft. We then make our way through a highly complex system of galleries and meanders, carved out by water over millions of years. A final series of shafts will bring us closer to the exit, after a climb of around 200 metres through the mountain.

We’ll then return to our starting point in the morning and complete this mythical and demanding loop.
