Pertes de l'Ain, Natural waterfall in Bourg-de-Sirod, France.
The Ain River plunges through a narrow gorge measuring two meters wide and one hundred meters long, creating waterfalls and whirlpools.
During the 16th century, the waterfall's hydraulic power supplied local forges before their replacement by a hydroelectric plant in 1898.
The site demonstrates local industrial adaptation with its former forges and hydroelectric plants harnessing water power for energy production.
Marked trails of 2 and 3.2 kilometers allow visitors to observe the river from the Les Chamois restaurant parking area.
The river disappears into an underground network carved in limestone ten million years ago, creating distinct geological formations.

The Jura department features varied landscapes with mountain ranges, limestone plateaus, and forested valleys. The terrain has shaped notable geological sites: the Hérisson waterfalls stretch over nearly 4 kilometers with 31 waterfalls, the Baume-les-Messieurs Reculée forms a closed valley with 200-meter-high walls, and the Langouette Gorges show a canyon carved by the Saine between vertical cliffs. Historic towns reflect the past of the region: Dole preserves its collegiate church and 16th- and 17th-century houses with arcades, Arbois hosts the Louis Pasteur house and wine cellars, while Salins-les-Bains displays its old salt production facilities listed as a UNESCO World Heritage site. The Jura vineyards produce specific wines, including the yellow wine made in Château-Chalon, a village perched on a rocky spur overlooking the vineyards. The Haut-Jura Regional Natural Park offers hiking trails and cross-country skiing routes. The ski resorts of Les Rousses and Métabief welcome winter visitors at over 1100 meters altitude. Glacial lakes such as Chalain allow swimming and water activities during the summer.
