Lac d'Issarlès

Lac d'Issarlès is a natural lake in the Ardèche region positioned at approximately 1,000 meters elevation. The water body spans a considerable area and features significant depths in its central zones.

The lake originated from volcanic activity that created a crater which gradually filled with water over geological timescales. This volcanic origin fundamentally shaped the formation of the water body.

Fishing remains a core part of local life here, with anglers regularly visiting to catch trout and char. This practice connects people to the lake and shapes how the community relates to the water.

A marked walking trail circles the entire lake with multiple rest spots and viewing areas along the route. The path is accessible and well-suited for a day visit.

The lake sits inside a volcanic crater and contains underground caves formed from volcanic material. This hidden geological feature remains largely invisible to visitors but makes the location geologically distinct.
