Sierra de Irta

Top choice in Castellón Province

To escape the summer crowds, seek solitude in the Sierra de Irta. Running south from Peñíscola, it’s both nature park and protected marine reserve, best explored on foot or by mountain bike. You can attack the full 26km of the circular PR V194 trail, or slip in one or more shorter loops. Ask at the tourist office for a trail map.
