Perched high up in the Aspe Valley, the newly renovated refuge (it just reopened in 2023!) is clean, functional, and run by a super friendly young crew with great vibes. Everything here runs on pure mountain energy. All the supplies are brought up and waste taken down by hard-working donkeys that march up the trails with total dignity. Don't expect a hot shower when you get to the top, though! You'll be freshening up old-school at the outdoor fountain, but you can instantly offset the cold water with some seriously delicious, hot food. Just remember to bring cash since card readers don't work up here in the clouds, and brush up on a little French or Spanish to chat with the crew.

The Ansabère Huts (Cabanes d'Ansabère) are as charming and laid-back as it gets. These little stone huts are used by local shepherds making fresh mountain cheese all summer long, and if you're lucky, you can even buy some right on the spot!

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.

A fairly difficult hike when you're not trained (which was my case) but not impossible if you take your time and go at your own pace. On the other hand, it's a very beautiful hike! The landscapes are magnificent. There are two parking lots, the Masousa parking lot and another higher up which saves 45 minutes, but the road is very bumpy.

Located on the heights of the Aspe valley, this renovated refuge reopened its doors in 2023. Hikers can come and spend the night there, have a good meal, simply have a drink or even just enjoy the dream view.

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.
