Beautiful forest and beautiful lake. Good walk to do when it is hot or when it rains because of the dense canopy. Perfect for dogs with a cooling stream. Sometimes the path was a bit overgrown and the search was always difficult, thanks to komoot. The beginning of the walk is also a bit difficult to find. Turn into the small road after the house and park the car there
