The beautiful chapel was built in 1931 after the valley's residents found the walk to the village for Sunday service too long. The chapel is made entirely of larch wood. According to Wikipedia, the construction cost 7,000 francs at the time.

The Cleuson Dam rises with its pronounced curves, creating a stunning backdrop to the Alpine landscape. As you reach the top, take the time to admire the turquoise waters held back by the imposing dam structure, which contrasts beautifully with the rugged mountainous surroundings. The view over the Val de Nendaz is simply spectacular and the effort of the climb is well worth it.

A wild and isolated mountain lake, hidden in the shadow of Mont Fort. The lake is filled with deep, turquoise waters, filled with meltwater from the surrounding rocky peaks - it's going to be cold, so I don't recommend diving there!

Beautiful climb to lac the Cleuson. Road bike is not the best as the last 3.5km is a gravelroad with lots of potholes. Especially the DH is therefore hard, since you have to go back the same way. However, it is doable with the road bike. The lake is beautiful and totally worth the climb. The climb is relatively good going up to the gravel part, there it is harder (11-15% parts up untill the top)
