Full information on driving restrictions.
The road linking La Lécherette and Corbeyrier on the south side of Lake Hongrin runs through the military zone of «Little Hongrin ». Unrestricted access to the area at weekends. Monday to Friday the road is closed for shooting exercises.
This same road goes through the Agites tunnel above Luan. This is a single lane tunnel and during weekends and bank holidays users must adhere to a strict timetable for one-way traffic. Cyclists need to be aware that the tunnel, carved out of the rock, has no other illumination other than a few shafts of natural light.
In winter, both the Hongrin road and the Agites tunnel are closed to traffic.
