Moules Marinières canyon


Moules Marinières is a canyon located in the Vercors massif near Trièves, 1 hour 45 minutes from Lyon, 45 minutes from Grenoble and 1.5 hours from Valence.

It is an atypical name because you can not find crustaceans there. The name is the mixture of the village name calls Morinaire, where we will have visit, and the water courses often call "Oules" in Occitant.

Moules Marinières, is a canyon of 1500 meters long, decorated by varies forms and styles of obstacles, perfect for discovering of the activity. After putting on the equipment at the meeting point, a car shuttle will take us to the starting point of the canyon. We begin with a 15-minute walk in the forest, which then lead us to walk along the river steam.

  • The first part, located in a continuous and calm collection, alternate walking and small fun slides.

We reach the first rappel of 10 meters that we use a rope to arrive in the magnificent collection of two slides, highlighted by an unforgettable playful light. In the exit, we resume a forest walk of 10 minutes along the stream, which allow us to have a moment to enjoy and observe the beautiful environment. We reach the second part of the canyon, which is much more technical, and astonishing.

  • The second part begins with a pathway under the passage of boulders in small caves.

The collection is well pronounced, light is scarce, sunlight is difficult to penetrate, leaving the narrow canyon makes it’s sense.

Then we are in front of the most beautiful obstacles, a jump of 7 meters (not mandatory and technique, variable depth according to the years) and a memorable rappel in a point of 17 meters with the unique aesthetic.

Once again, the canyon opens to the way of exit in chaos of boulders where you need to walk precisely, and two last beautiful surprises are waiting for you : A new jump of 7 meters without difficulties (variable depth according to the years). You will arrive in a pool that will take you to the largest toboggan in Isère. It's a sensational 10-meter slide. What an end!

After taking a photo for souvenir, we will have a 5-minute walk to get back our cars in the starting parking.

This canyon is only practicable from 1st June to 30th September.
