A good base for mountain bike tours through the Val d'Azun, as there are several parking areas. A pump track has also been built on the edge of the village.

Superb hike, the only downside is the starting point. Park in the village, two parking spaces are available. I was unable to reach the starting point by car. Up to the Liar pass it climbs quite a bit then it's just a long walk.
