On the occasion of Heritage Day, visit the Pont des Pierres Regional Nature Reserve along the water to learn more about its use in the Valserine valley. The Stone Bridge Gallery is an underground site dug by man for a former hydroelectric power plant project that was abandoned in the 1930s. With its exceptional natural heritage, both on biodiversity with the presence of bats, but also on the landscape and its history, the site is classified nature reserve in 1997.
Appointment at 14:00 at the Pont des Pierres car park on the Comfort side: https://goo.gl/maps/dh4u1KwoYzog66XS9

The classification is effective on December 8, 1997 by Prefectural Decree and the regional federation "CORA Region" became manager of the RNV, under agreement with EDF.
In May 2005, the decree implementing the law on democracy of proximity places the Nature Reserves cal
