A sporty route starting from Koestlach, this circuit crosses the Ill valley, known in particular for its beautiful half-timbered houses and flowers. A small detour through the forest of Durmenach will allow you to prostrate yourself before the king of the places, inscribed in the French genetics: the larch.
