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.

The impressive panorama of the Ain River at one of its widest points. The Ain is a river full of fish where trout are caught. Many birds populate the banks of the river: ducks, egrets, swans, herons, snipes. Beavers are also present, particularly in the lower reaches (Lower Ain valley).
