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").

A short, fun 7km outing without any major difficulty, before a delicious plate of frogs or trout at the waterfall restaurant. Book now!

Lacs de Maclu are two adjacent lakes in the western part of the French Jura, in the Jura department of Franche-Comté. They are located at an elevation of 779 m in a depression in the High Jura, in the region of the Five Lakes near Le Frasnois, about 12 km south of Champagnole. The Petit Maclu, located to the northeast, has an area of 5 hectares, a length of about 500 m, and a maximum width of about 120 m. Its greatest depth is 11 m. It lies entirely within the municipal territory of Le Frasnois.

Climbed it today (17-8-25); it's open, and there are signs along the road showing your progress. Traffic is quiet, and a beautiful green climb, especially further on.
