La Balme Caves

Highlight • Cave

In the caves of La Balme one can look back on a long history: Various archaeological finds indicate that the caves were already inhabited by people at the end of the Bronze Age. Later, in the 9th and 14th centuries, two chapels were built at its entrance. During the 18th century, rumors spread that a famous French smuggler was hiding in the grotto. Visitors can explore the caves on their own along a paved path about a kilometer long. Guided tours are also available on request.

La Tuille Pond

Highlight • Lake

Optevoz has been occupied since the Bronze Age.
In the 19th century, limestone mining and agriculture were the main activities. At this time, the village became a place of stay for many painters seduced by the light and the landscapes (in particular the Vanne d'Optevoz represented in numerous paintings).
