The quarry also offers a beautiful view of the valley. This highlight can also be reached with a short hike from the Uchentein d En Haut car park.

Just before the Col de la Croix, the Mail de Laroque offers breathtaking views of the surrounding mountains. It is located at almost 1,400 meters above sea level. The rocks are quite impressive!

The Morères cabin is an unguarded shelter in the Pyrenees which has a table, two benches and a small stove. You have a water fountain nearby.
