Castellón
The Province of Castellón is in eastern Spain. It's known for the Costa del Azahar, with beach resorts such as Benicàssim, Oropesa del Mar and Benicarló. The 13th-century Peñíscola Castle has panoramic coastal views, and a botanic garden in the neighboring Artillery Park. The Columbretes Islands are a haven for nesting seabirds. Inland, trails criss-cross Mount Penyagolosa, home to red pine trees and eagles.
