Descente en rappel de la 1ère cascade de l'Alloix


Located in the Chartreuse massif, halfway between Grenoble and Chambéry, the Alloix waterfall canyon is one of the must-sees in the Grésivaudan valley for those who like to rappel down.

It a canyon with beautiful vertical parts to go down in rappel, as for example the rappel down of the “cascade Oubliée”, at the level of Nepalese bridge in the old Saint Vincent de Mercuze Via Ferrata.

The longest abseil is nearly 150 feet high in the highest waterfall among Alloix Falls. This abseil is quite original and impressive: we descend freehanging abseil. This means that you won't touch the rock neither with your hands nor with feet because the waterfall cliff is overhanging.

The Alloix Canyon is a good training test to engage to more difficult harder routes as the canyon, upper part of Écouges Canyon. Further down the canyon route, one will find some small jumps and a beautiful waterslide.

The green surroundings, this beautiful places and the fresh make part of the program in this nice canyon course that remains uncrowded compared to other canyons in the region.

It is also possible to make a shorter version, only 3 hours canyoning instead of the 4 hours required by the full version, starting at the bottom of the grand 150 ft high waterfall, which avoids the first three long rappel down.
