It is located in the north of the Region of Valencia in eastern Spain, and is known by the brand name of Castellón Costa Azahar. Its 120 km of coastline has everything from beaches to coves lapped by the Mediterranean Sea, and natural spaces such as the volcanic archipelago of Islas Columbretes, a nature and marine reserve of volcanic origin. There are numerous holiday resorts all along the coastline, such as Benicarló, Peñíscola, Vinaròs, Oropesa del Mar and Alcossebre.
