This small road which passes by the Col de Landoz-Neuve starting from Mouthe to join the Lac de Joux is very little frequented and never controlled. You will pass through Switzerland without realizing it.
Traffic-heavy transition between Vallorbe and Le Pont. Coming from Vallorbe you have to overcome a difference in altitude of a good 320 m, whereby it becomes a little steeper for a good 1 km in the middle part.
The Col de Mollendruz is a road pass located at an altitude of 1,180 metres. It is also the starting point for many hikes and a great place to admire the Alps.
