This mountain range in the interior of Castellón belongs to the Iberian Range and has a unique geology, climatology and ecology that make it one of the most valued natural environments in the entire Valencian region.

Its Mediterranean ecosystems develop on silicic materials in the form of red Triassic sandstones. This hard and rough geology shapes a rugged terrain with steep slopes and filled with walls and rocks. In every corner, the red of the rock and the ground contrasts with the deep green of the foliage and the trunks of maritime pines and corks, the true identity signs of this territory.
