Departure from Saint-Vincent-de-Mercuze (Isère)
Numerous streams flow down from the Petites Roches plateau into the Isère valley, creating several spectacular waterfalls. This route allows you to explore those at the northern end of the Petites Roches plateau, which are not part of the ‘Tour des Petites Roches’GR® de pays route, which runs further south. If the full hike is too long, you can use this as inspiration for easier alternatives.

For an ascent of the Dent de Crolles, it is possible to take the route via the Pas de l’Oeille.
