Near the lake, two caves are dug into the cliff. The upper cave served as the lake warden's dwelling until the beginning of the 20th century. Today it is set up as a museum recounting the history of its troglodyte inhabitants. As for the lower cave, it has remained as it is. It is via a perfectly laid out path which, after a 300-meter walk, leads visitors to the famous dwellings. No one remembers the time when these caves were dug. https://www.ardeche-guide.com/patrimoine/grottes-troglodytiques-299828/

The loop trails are very nice! Small disappointment once at the top not to find a spot where you can enjoy a picnic with a view of the lake :)

At 1,343 meters above sea level, the Suc de Cherchemuse is an ancient volcano in the Velay region. From its summit, you benefit from a pleasant view of the great juices of the Mézenc massif.

Stroll around the lake on Sunday July 23, 2023. Very pleasant because it is largely shaded. Provide credit card (no possibility to pay in cash) for paid parking from 01/06 to 30/09, package 3€. Lots of people on the beaches and around.

While jogging around this lake, be aware that it is extremely deep (138 m)! The lake was created by the escape of magma from a chamber below the lake.
