SWIMMING

There is a swimming pool in La Tzoumaz housed in the ski lift building.

Down in the valley is the Spa in Saillon and also the lovely lake, La Domaine des Iles. Both definitely worth visiting!
Why not treat yourself to one of the several Thermal baths in the area.  The Spa in Saillon is set in the heart of the Valais vineyards and has plenty to offer and is also great for kids.
