You can rent sailing boats or motor boats at the reservoirs of the l'Eau d'Heure and the Plate Taille. Other water sports include canoeing and diving. You can also dive at the stone quarries.

At 10 minutes drive from the camping, there is an Aqua-centre with swimming, both in- and out door (indoors there is a sub-tropical swimming pool, saunas, and a Turkish bath). 

There are also a number of fishing lakes.
