The magnificent ruins of the Fort de Buoux are on top of a high stone butte in the Luberon mountains, about 10 km south of Apt and 8 km east of Bonnieux, overlooking the deep ravines of the Aigue Brun river. There are parking places past the "colonie de vacances", just off the little D113 road, and it's only about a 15-minute hike up to the start of the fort.

The short hike takes you past the largest "baume" in the Luberon (a natural cave beneath overhanging cliffs). Human habitation here and in other caves in the surrounding cliffs date back to prehistoric times, and has continued throughout history to the present.
