The Saut de la Saisse is a waterfall in France located in the Jura massif, at the point where the Ain river flows into the Vouglans reservoir at Pont-de-Poitte and Patornay, between Lons-le-Saunier and Clairvaux-les-Lacs. A "marmite du diable", "marmite de géant" or "marmite glaciaire" in Switzerland (or simply "marmite" or "chaudron") is a more or less cylindrical natural cavity carved into the rock by ancient, generally torrential watercourses, carrying pebbles or gravel, which promotes swirling erosion (a phenomenon called "marmitage").

Great view of the Ain, this is where the Lac de Vouglans begins. When the water level is high, the stones are of course not so easy to see.

There are currently no waterfalls. Not a single drop of water💧. No wonder given the drought ☀️🥵.

The La Fratte belvedere is accessible by a small path that branches off. to get closer to the cliff. The viewpoint is secured by barriers and thus allows you to enjoy the view in peace. And the panorama is really worth it: turquoise water and forest as far as the eye can see.
