Morgins – Rainbow Waters Hike

Morgins

'Morgins, les Couleurs de l'Eau' is a fascinating interpretive trail, featuring nine informational panels in the valley of They, between Morgins and the Portes du Soleil pass.

The trailhead is located at the entrance of the Vallon de They, just past the Morgins Ranch.

The itinerary offers nine interpretive panels along the route through the They Valley, between Morgins and the Col des Portes du Soleil.

Walking upriver to the source of the Vièze, you’ll see that the water changes colour; alternately red, blue, yellow, white, and green! The panels provide geological, hydrological, and hydrogeological explanations as to why the colours change so strikingly, how water and minerals interact, how water can suddenly disappear or appear out of nowhere, and why these mountains are so uniquely special.

Keep your eyes peeled for:
– Red at the Eau Rouge Spring
– Blue at the edge of the Vièze River
– Yellow at the Fontaines Jaunes
– White at the Fontaines Blanches
– Green at the Lac Vert

You’ll find alpine restaurants along the way – the Chésery Hut at Lac Vert, or the Tovassière and They ‘Cantines’ in the They Valley.
