Etang de Lers is a lake at 1,274m altitude at the intersection of the Vallée de Massat, the Vallée de Vicdessos via Port de Lers and the Vallée d'Aulus-les-Bains via Col d'Agnes. Dominated by Mont Béas, Mont Ceint and Pic des Trois Seigneurs (2,199m) and surrounded by vast, gently sloping meadows, the lake is one of the loveliest places in the Ariège Pyrenees.
The lake area, at the heart of the Parc Naturel Régional des Pyrénées Ariégeoises, is rich in natural habitats and wildlife and is a Natura 2000 conservation area. It is also well-known to geologists all over the world for lherzolite, a rare igneous rock, which gives the landscape a lunar appearance in stark contrast to the vegetation.
The site has been a summer pasture for cattle, sheep and horses since time immemorial, as can be seen from the remains of ‘orris’ (stone huts and enclosures). Nowadays the lake is also the site of lots of other activities.
In winter it is a winter sports venue for cross-country skiing and snowshoeing. In summer it is the starting point for walks and discovery trails. You can also go paragliding and caving, or simply enjoy a lovely day out in exceptionally beautiful countryside.
Etang de Lers is also a paradise for fishermen at the heart of the regional natural park! Open between May and October, from dawn to 19.00, a fishing party alone, with friends or family at the lake is a great day out. It is a recognized tourist fishing spot and is regularly stocked (twice a week in summer) so it is easy to catch brown trout, rainbow trout and brook trout. There is also a « Handipêche » pontoon for fishermen with reduced mobility next to the lake outfall.
Also in the area - Aulus les Bains thermal baths.
