Lac de Vert, tunnels and viaduct from Talencieux

Starting from Talencieux, the route passes by Lac de Vert, then the Midon tunnel and a short detour through the countryside before returning to the old railway line to cross the Thorrenc Viaduct, the Thorrenc Tunnel and the Thorrenson Viaduct. Don't forget a headlamp or other light for crossing the two tunnels.
