Lac Potron

Lake Potron is located on the Wetlands Trail proposed at the Col de la Croix de Fer:
The Syndicat Arvan-Villards (SIVAV) has created an interpretation circuit on the wetlands, lakes and peat bogs located at the Col de la Croix de Fer, in Saint-Sorlin-d'Arves. The SIVAV has set up a signposted walking route with 5 thematic observation points. The panels were designed by France Nature Environnement and then attached to existing trail posts. They are subsidised by the Water Agency within the framework of the Arc River Basin Contract.
