Puech de Rascas, Military summit in Lacaune Mountains, France

Puech de Rascas is a mountain summit in the Lacaune range that reaches 1270 meters and serves as the highest point in the Tarn department. The peak is fully occupied by radar and radio installations that dominate the upper plateau.

The summit is occupied by military radio and radar installations and depends on Air Base 125 Istres-Le Tubé. The sources give no date for the establishment of these facilities, and the summit is not accessible to hikers.

The name comes from Occitan, in which puech designates a height or summit; the Catalan form Puèg de Rascas is also recorded. The summit is the highest point of the Lacaune mountains and of the Tarn department at 1,270 m, just one metre above the neighbouring puech de Montgrand (1,269 m).

The summit is strictly off limits to hikers because of the military installations that cover the entire peak. The surrounding mountain trails offer walkers a chance to explore the landscape from different viewpoints, though the top remains inaccessible.

At 1,270 metres, Puech de Rascas is the highest point of both the Lacaune mountains and the Tarn department, just one metre above its neighbour Puech de Montgrand at 1,269 metres. The summit belongs to Air Base 125 Istres-Le Tubé, which operates the radio and radar installations visible on the plateau.
