La Dehesa

La Dehesa is a Paraje Natural Municipal (municipally protected natural area) located in the municipality of Soneja, in the Alto Palancia comarca, Castellón province, in Spain's Valencian Community. The protected area covers roughly 580 hectares and was officially designated by the regional government (Generalitat Valenciana) on 5 November 2002.

Where exactly is La Dehesa located?

The area sits on a high plateau at around 440 metres above sea level, in the mountainous inland part of the Alto Palancia region. This setting gives the landscape a very different character from the coastal areas typically associated with Castellón — expect dry, rocky highlands crossed by patches of forest and Mediterranean scrubland rather than beaches.

What makes this natural area distinctive?

At the heart of the site is a temporary endorheic lagoon — a body of water with no outlet to the sea, which fills according to rainfall and can partially or fully dry out during drier months. It sits on a bed of siliceous sands and Triassic clays, a geological combination that is rare in the mountainous parts of the Valencian Community. Because of this uniqueness, the lagoon has been included in the Catalogue of Wetlands of the Valencian Community (Catálogo de Zonas Húmedas de la Comunidad Valenciana).

What plants and wildlife can be found here?

La Dehesa is an agropastoral landscape, meaning traditional livestock grazing has long coexisted with the natural vegetation. The area is home to rare, endemic, or endangered plant species, including Crassula campestris, Chaetonychia cymosa, and lavandula pedunculata (a wild lavender). A particularly notable feature is the presence of cork oak trees (Quercus suber) — their presence at this altitude and in this region is fairly unusual and points to specific microclimatic conditions on the plateau.

Are there traces of earlier human settlement in La Dehesa?

Yes — six archaeological sites dating from the Bronze Age and the Iberian period have been identified within the protected area. This indicates the plateau was inhabited and used by people thousands of years ago, most likely thanks to the access to water provided by the lagoon and the fertility of the plateau, which would have supported both grazing and cultivation.

Can visitors explore the area on foot?

A marked hiking route, PR-CV 320, shares its name with the natural area itself and runs through La Dehesa. The trail takes walkers through the site's most notable features — from the edge of the cork oak woodland, across the open plateau, to the surroundings of the seasonal lagoon. It is popular with local hiking groups and nature enthusiasts from the Castellón region, who value it for its tranquility, distinctive vegetation, and opportunities to observe birds and other wildlife associated with the wetland environment.

Why is La Dehesa worth visiting?

This site brings together several elements rarely found in combination: a mountain plateau, a seasonally drying lagoon of significant ecological value, cork oak woodland more typical of lower and damper terrain, and evidence of human settlement stretching back thousands of years. For visitors to Castellón province looking for an alternative to the coast, La Dehesa offers a quiet inland excursion through a landscape that changes character with the seasons — appearing at its most striking when the lagoon fills with water after the rains.
