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.

Beautiful singletrack over the Crête, offering stunning views of the Cirque de Litor on one side and the Val d'Azun on the other. The final section of the singletrack, descending to Lac de Soum, is a bit more technical.

A gentle, narrow climb. From the west, the gradient is consistently high, with no respite. The asphalt is in good condition on both sides, making it easy to descend as well.
