The Dentelles de Montmirail are the farthest western strip of land of the massif of the Baronnies, which includes the Montagne de Lure and Mont Ventoux. The Dentelles de Montmirail owe their name to the sharp profile of their peaks and walls faces, on which there are about 600 ways for rock climbing. The rock is of Jurassic limestone and the environment is typically Mediterranean, with holm-oaks and Aleppo pine trees. At the feet of its faces there are fine vineyards and some mineral water springs.
