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.

Crater lake, 1,000 meters above sea level with a very pleasant beach for swimming. Very calm. Good food options around and public restrooms.

More of a symbol than an exceptional site, but a beautiful symbol.

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.
