Christophe and his team welcome you to the Seythenex cave and waterfall site.
A sign of fate, Christophe was born in this small village just a few hundred meters from the site. As a child, he used to play with his friends in this cave and near the waterfall, which, at the time, were not open to the public.
With his pastry chef diploma in hand, Christophe traveled around the world for 11 years, eventually settling for a while in Thailand, where he opened a bakery in Koh Lanta. Upon returning to France, he reconnected with the managers of the site from his childhood, and in 2011, Christophe took over the business. Very quickly, alongside his brother in the early years, Christophe modernized and enhanced the site. In 2012, he installed the first zipline, which was an immediate success. Then, in 2018, he installed two major zipline courses.
Quiet and reserved, Christophe now leads a team of six people in a family-like atmosphere that you can feel as soon as you arrive. As he himself says, “I spent a long time searching during my travels around the world, but in the end I found happiness right next to home.”
