The Pic de Bugarach or Pech de Bugarach (puèg de Bugarag in Occitan, i.e. “Bugarag Height”) is the highest summit (1230 m) in the Corbières mountains (A1ude, France).
The peak is also called the “upside down mountain” as the top layers of rock are older than the lower layers due to uplift of the Pyrenees.
It is also located on the Green Meridian.
