Unique in the Hautes-Alpes, in the heart of a sensitive natural area, discover the richness of this specific environment by following a path on stilts that takes you into a nature that is usually inaccessible.

On-site, make your walk interactive by using your mobile phone to connect to the DNS marker on the "eco-balade" page. You'll then have access to the flora and fauna you can observe around you.

Accessible to all, the trail is made up of a mosaic of landscapes and has been specially designed on stilts to preserve the ecosystem.
Passing discreetly over the water, discover the wealth of natural habitats as you cross a forest drowned in the sandy fill of the Lac de Serre-Ponçon.

And all this right next to a shopping area!

Important information

Dans le Parc national des Écrins, les sentiers sont généralement praticables de la mi-juin à fin septembre.

Toutefois, les périodes d'accessibilité des itinéraires et les dates de pose des passerelles varient d’une année à l’autre en fonction de l’enneigement, des dégâts survenus en hiver et des conditions météorologiques. Par ailleurs, l’état des sentiers n’est pas contrôlé quotidiennement et peut évoluer rapidement après un évènement météorologique (orage, crue...). Il est nécessaire de se renseigner auprès des maisons du parc national et des offices de tourisme du territoire avant votre sortie. Pendant la randonnée, en cas de passage dégradé ou dangereux, faites demi-tour et signalez-le.

Description

At the start of the cul-de-sac used as a car park is the explanatory panel marking the start of the Petit Liou wetland discovery trail.

This is where you can log on to the "eco-balade" page, which serves as a guide and information document for the walk.

Take the path towards the river.

Turn right, and walk down along La Durance.

A hundred or so metres further on, the stilted path begins on the left. It is possible to make a round trip to the end of the dam from this point.

The path is interrupted by a vague track that you must follow in the direction of the lake for around a hundred metres. The path starts again on the left and soon gives way to a wooden footbridge over the water.

Follow the path on stilts along the information panels about the area you have crossed until you reach an observation tower overlooking Lac de Serre-Ponçon. From there, return by the same route.

Departure : “Les portes du Lac" shopping area
Arrival : Observation hut at the end of the footbridge
Towns crossed : Baratier and Crots

Water
The Durance
The Durance rises near the Montgenèvre pass and flows into the Rhône near Avignon. It feeds lake Serre-Ponçon and is a real asset to the region's economy, thanks to the host of activities it supports: water sports, hydroelectricity and agriculture. Over 320 kilometres long, it is the most important river in Provence. In the past, the Durance was reputed to be impassable, due to its strong flow and great width.
Fauna
Pike
A carnivorous fish that can grow more than 1 metre in length, with 700 teeth, it is sometimes nicknamed the "freshwater shark". Don't worry, a pike will never attack a swimmer, but record catches of up to 1.30 metres have made Serre-Ponçon lake famous among anglers from all walks of life.
Sedentary and solitary, pike thrive in calm waters with weak or stagnant currents. In these waters, it chooses places where it can hide (seagrass beds, stumps, etc.). Generally living concealed in vegetation or in the darkness of the seabed, it has a lifespan of 10 to 15 years. It breeds from February to March. From 15,000 to 45,000 eggs can be laid in mid-June as soon as the lake covers the wet meadows in the Liou area.
