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.
