(S/E) After admiring the landscape with its beautiful pond, continue northwards. After 100 metres, at the crossroads with a bench, turn right. The path enters the forest.
(1) At the edge of the forest, at a place called Les Grands Champs, turn left, heading due west, making a hairpin turn. Continue straight ahead on a beautiful stone path that enters the forest again.
