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!

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.
