Via sous-terrata

Using the same techniques as for via ferrata but this time underground, via sub-terra opens up the way for you to go 50 metres down into the Earth to discover caves, chasms and fascinating multi-concretion landscapes.  The route is spectacular and varied, fully equipped and secure: suspended walkways, tunnels leading to natural caves, monkey bridges and lift wells. Enjoy an original, fun and safe introduction to the subterranean world.
