Pure mountain magic sitting at nearly 1,900 meters up in the Echo Valley, Ibón de Acherito is hands-down one of the coolest glacial lakes in this part of the Spanish Pyrenees. It’s tucked right into a big, rocky bowl of steep limestone cliffs that make the whole place feel super hidden and special.

Lake Ansabère it's a pure alpine chill into a beautiful high valley. You’ve got this quiet, clear mountain lake sitting right beneath the crazy jagged limestone needles of the Ansabère peaks, with sheep and horses just hanging out on the green grass nearby. It’s an dream spot to kick off your boots, pull out your lunch, and just relax by the water while watching the peaks mirror on the lake.

Great view at the summit of Agua Tuertas pista. There is an unguarded shelter before the Agua Tuertas section in which you can rest for the night, with tables, chairs and even a cheminée.

A few steps from Spain, surrounded by the Aiguilles de Lescun, Lake Ansabère culminates at an altitude of 1,859 meters in a breathtaking setting!

From the Aguas Tuertas refuge there is a short path to this dolmen. The detour from the GR 11 is well worth it, as it is impressive to see this megalithic monument, one of the best preserved in the Aragón river valley, in such an overwhelming natural environment.

Charming lone lake. The westernmost of the Pyrenees. It is always worth a visit.

The valley that takes the road to the refuge of Aguas Tuertas, in its last meters, appears a zig-zag, with a slope, before reaching the refuge. Once there, the views towards both sides are spectacular, especially the Humedal de Aguas Tuertas where immense meanders occupy the foot of the valley.
