An accessible 3000m peak with a magnificent view of the Piau-Engaly resort and the Cap de Long lake. Be careful of the slab before the summit which can be a bit dizzying

Wonderful landscape. I had planned it more by chance.

Small Pyrenean road, little frequented by cyclists, but perhaps one of the most beautiful in the Pyrenees in a high mountain atmosphere

Be careful of the descent and the sometimes violent wind arriving at the top of the pas de gat. The view is exceptional

During the climb you can take a nice break here and enjoy the view over the valley.

The Pic du Campbieil is easy to reach; when ascending or descending to the east there is only a slightly exposed, 20m long passage over a steeper stone slab. Mainly a matter of your head, but to the left there is a steep descent over the grade and slipping leads directly onto the scree field. Before/after it just continues.

The Pic d'Estaragne is relatively easy to reach for a 3000m peak. The ascent and descent from the north can be hiked in its entirety. The real summit is about 10 minutes further west of the summit indicated on Komoot and the first viewpoint towards the Spanish Pyrenees that you reach. Once at the top, you can follow the summit ridge and reach two more pics. The terrain becomes a little more difficult, but still doable.
