Departure from Naut Aran (Lleida)
The Colomèrs lake circuit is a massif of mountains arranged in a circle, protecting some fifty lakes ("estanhs") in its bosom. The slow erosion of frost during the Ice Ages has left an inescapable landscape: a high mountain area with high, steep peaks of around 3,000m, such as Creu de Colomèrs, Gran Tuc de Colomèrs and Tuc de Ratera.
