Cafes, bakeries and bars but also a public toilet and drinking water tap (at the back of the church). The climb to the Azun Valley, Soulor, Aubisque starts here.

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.

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.

Nice climb, few cars, be careful on the descent, the asphalt is smooth but the grip is not the best, moreover some bends close. A great champion fell here during a TdF.
