The site is not accessible by wheelchair. The cave itself involves narrow galleries, several flights of steps, and some low passages, and the outdoor paths include uneven, sloping ground.

What to see at Cascade de Sassenage
The Cuves de Sassenage are a set of caves carved by the underground Germe river at the foot of the Vercors cliffs. First opened to visitors in 1947 with barely 200 metres of pathway, the site now offers more than a kilometre of galleries showcasing rock formations shaped by running water, at a constant 12°C year-round.
Outside the cave, a path along the Furon torrent leads past the entrance and, on the return leg via the opposite bank, gives views of the Cascade de Sassenage in its wooded setting. This outdoor loop is the part currently affected by the fire-risk closure.
Inside, a themed son et lumière show tells the legend of Mélusine, a water fairy said to have been cursed to change shape, her legs turning to a serpent’s tail every Saturday. The site is also a starting point for canyoning trips down the Furon gorges for those seeking a more active visit, and it is close to the historic Sassenage Château and its gardens.
