Tunnel leading to Harel wood on the left. Small wood that allows for a bit of off-road with an exit onto the road. Plan for some bunny hops.

This beautiful sunken path, a veritable tunnel of branches and leaves, is a treat of slightly challenging gravel, descending from east to west. Watch out for the roots and stones that punctuate these 800 meters.
