ボンリュー湖のおすすめライド

The smaller of the two Maclu Lakes, with an easy hiking trail along its shore.

A waterfall with a larger pool and a smaller cascade in a beautiful setting. In front of it is a small stone lynx statue.

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.

Easy, shaded path, perfect for cooling off in hot weather.

Classified as 3rd category, the Col de la Joux was crossed during the 8th stage of the 2017 Tour De France!

Watch out for Ice in the winter, can you find the secret waterfall ?

On most maps it is called "Lac d’Ilay". The other name probably comes from the small island "Île de la Motte" which is located in the lake.
