FR-01 Lake Genin – Gravel 40 km, elevation gain 900 m, 4 passes

Author description

Author : Philippe Chazottier
Course : completed on 17 August 2025
Departure Location: Apremont, south of Oyonnax. Roadside car park 500 m before the southern entrance to the village.

Tourist information

The Oyonnax forest and the surrounding area Lake Genin are nicknamed «Little Canada»: a haven of coolness in summer and grappling with overtourism, with some blaming «social ills»; winters there are particularly harsh, with the lake freezing over; you can even go ice skating there, as well as ice diving!
Le Lake Genin has the distinctive feature of being privately owned. However, an inn and a campsite run by the owners allow visitors to enjoy it to the full without any apparent restrictions on access.
There is a large car park next to it, but I would advise against using it given how busy it gets on fine days.
A 20-minute drive from Apremont, the site of Dinoplagne offers a view of the largest site of dinosaur footprints known to date.

Technical specifications

Rateable at 98 %, the route is mostly on roads and does not present any major difficulties. During my ride, I decided against heading to the Roche-Taillée gully (FR-01-0914b) as well as the Collet de Châtel (FR-01-0760) because of rutted forest tracks.
