This reservoir offers a triple advantage: being able to cool off while contemplating the mountains and numerous birds. Recent droughts have repeatedly affected the water volume of this lake. Find out before you go.

This rather unusual topographical feature must have been the seat of some sort of defensive building. Today, only two crosses remain and the breathtaking view that can be had at the top.

A small castle with lots of details and intrigue. It is of course a private property, but you only have to see it from the road to realize that.

The best thing to do after visiting the top of this motte is to see it from here in relief. It is strangely a perfect cone or rounded shape. It is very impressive.

The Moncassin village is built on a ridge overlooking the Petite-Baïse. Le Castéra, located on a limestone promontory dominating the valley, is one of the most remarkable castle mounds in Gascony.
