Visit of the Seythenex cave and waterfall

It has been visited since 1906 and offers 250 meters of galleries to discover on an underground path, punctuated by walkways. The geological interest of the Seythenex cave is immense. You can observe the different calcite strata there. The typical formation of its hoses, called "keyhole" testifies to the way in which the waters have shaped these underground galleries, first digging circular conduits and then eroding the rock downwards, when the water no longer fills fully galleries. The visit to the cave is guided, and lasts approximately 35 minutes.
 
Another natural gem to discover on the site is the Seythenex waterfall. The fall is that of the waters of the Saint Ruph, a torrent that rises at the Col d'Orgeval to reach Lake Annecy. With its 45 meters in height, it offers a striking spectacle. Below, the tumultuous waters of the river form sublime giant pots before continuing their descent to the lake. A guided tour of the site is offered, as well as its overflight by zip line: an unforgettable experience in an exceptional natural site, 40 meters high and 150 meters long.

The site of the Seythenex cave and waterfall finally has a projection room which broadcasts a documentary film on the daily life of the inhabitants of the region during the past centuries. You can also admire a model that reproduces the landscape of the village with old houses, workshops of artisans, water mills on the Saint-Ruph and the millstone that they allowed to operate.
