The Rangenberg is a protected natural area, located in the heart of the vineyard of Dorlisheim. This hill is made of both dry grasslands and dense vegetation. A rich biodiversity has been preserved: many types of wild orchids have thus been identified here. At the foot of the Rangenberg, towards the plains, is the "Puits d'Amour" (Well of Love), a place where flows a small natural stream of water surrounded by a cut stone arbor and some fruit trees.
