For an unique natural experience, plan an excursion to the bubbling pools of Lavey Spa. This place is famous for its mineral-rich thermal waters.
Situated in Lavey-Morcles, this naturally heated water source is well worth including on your itinerary. But you'll find plenty more to see in this area. Barboleuse-Les Chaux Gondola, Barboleusaz - Les Chaux, and Ovronnaz Ski Resort aren't too far away from Lavey Spa.
