The pass road runs on side road 152a from Le Pont (1008 m a.s.l.), a village in the municipality of L'Abbaye, northeast along lake Brenet, over the Col du Mont d'Orzeires, past Pierre Punex (1061 m a.s.l.) and continues to Chalêt du Mont d'Orzeires (1029 m a.s.l.), where the Juraparc animal park is located. After a few bends, the road runs from a height of 950 m a.s.l. to the east to La Dernier (764 m a.s.l.) and Vallorbe (749 m a.s.l.). The pass connects the Valle de Joux through the narrows between the Risoux range and the Dent de Vaulion (1483 m a.s.l.) with main road 9 near Vallorbe.

Tunnel

The Pont–Vallorbe Railway (Chemin de fer Pont–Vallorbe) built a railway tunnel through the Mont d'Orzeires, which is traversed by the Vallorbe–Le Brassus trains. The tunnel was built in response to a petition from the residents of the valleys of 1867[1] and opened in 1886.[2] It had a dual function, as it was not only serve the railway but, in the case of an extraordinary flood, it could also be used to empty water from the two lakes.
