July 31, 2026, Ibón de Estanés

Sitting right at 1,754 meters on the Spanish side of the border, Lake Estanés (Ibón de Estanés) is a total Pyrenean classic. Grassy basin at the foot of towering, rugged limestone peaks, this spot feels completely timeless the second you step down to the shore. Also it's a local favorite and literally never disappoints!
