You start at the Col de Pre, a small pass with a narrow road, but very worth seeing.

Long walkway to cross Lake Saint Guerin, be careful with hikers, the walkway is narrow and moves a bit.

The path ends at a farm where there is this huge dog that will chase you for a while barking until you get out. If you get off the bike he will stop barking. I think he doesn't like bikes 😒
