Castellón en Ruta Cultural is a cultural and nature-focused initiative of Fundación Caja Castellón, dedicated to helping people discover the landscapes, heritage, and traditions of Castellón province. Its website shares information and stories about the region and promotes ecotourism through guided routes, hiking, and other outdoor activities. Visitors can explore themes including local history and archaeology, nature and science, gastronomy and wine, crafts and ethnology, festivals, legends, religion, art, and literature.

The programme offers scheduled excursions, route registration, and activities arranged on request. Its featured experiences include walks in areas such as Ares del Maestrat and the Barranc dels Horts, as well as family-friendly nature routes and educational activities. The organisation also provides nature-learning opportunities through Escola de Natura Seidia and promotes summer camps for children and young people, alongside programmes for schools and institutes. In addition to visitor activities, Fundación Caja Castellón publishes reports and supports rural revitalisation initiatives, including grants aimed at addressing depopulation in rural municipalities.
