Colomers, located at the top of the Aiguamòg valley and the southernmost tip of the Val d’Aran, is home to the most important concentration of lakes in the Pyrenees. In summer, it’s one of the most popular hiking destinations. In winter, the presence of snow in the valley makes access rather difficult. So, we’d suggest a two-day trip with a night at the new Colomers Mountain Shelter, semi-accessible from December to February and thereafter open until spring. From the shelter, the possibilities are numerous, such lakeside walks or a range of climbs of varying difficulty. The important mountain passes of Puerto de Caldes, Colomers, Ratera and Còth de Sendrosa connect this shelter with other shelters in the National Park of Aigüestortes i Estany de Sant Maurici.

During the winter, the access road to Banhs de Tredós remains closed at the Bòrda de Montadí. From the car park, follow the track towards Banhs de Tredós to avoid making a detour before the forest. From Banhs (when the snowline has risen in springtime, access by car reopens to here), keep on the track that passes beneath the attractive channels of Tuc de Sendrosa. These channels can be dangerous and should be avoided after heavy snowfall or prolonged melting by warmer temperatures or rain, when avalanches often end up cutting off the track. Cross the Arriu d’Aiguamòg through the Pònt la Montanheta and either stay on the track or take another shortcut. At the sign for the Colomers Mountain Shelter (altitude 1975 m), leave the track to follow the summer path that meanders along the right bank of the ravine up to Estanh dera Lossa. Cross the wooden bridge and keep going up the ravine. After a short while, you’ll reach the inlet of the Estanh Major de Colomers lake. Cross it to access the old Colomers Mountain Shelter, from where you’ll be able to see the new shelter. Walk around the lake and your destination will be in front of you.
