The Serra d'Irta Natural Park, situated alongside the d'Irta Marine Reserve, is a protected area of 12,000 hectares of land located to the north of Alcossebre.
Its flora is that of a semi-arid zone with a Mediterranean climate. The pine groves live in harmony with the Mediterranean dwarf palm, rosemary and fennel. The substrate of white calcareous rock makes for a spectacular coastline, with cliffs that alternate with small coves.
The Park is located to the north of the Comunitat Valenciana, between the towns of Peñíscola, Santa Magdalena de Pulpis, Alcalà de Xivert and Alcossebre.
It represents one of the last Mediterranean coastal hill ranges still untouched by construction and is one of the most beautiful landscapes along the coast of Valencia. Its highest peak, at 572 m, is the Campanilles peak, and its steep slopes descend gracefully towards the sea, along 12 km of coastline. There, practically unchanged, are numerous cliffs and coves. Over time, as a result of the continual erosion by water at its base, caves, cavities and outcrops are formed, creating a habitat for various seabirds (gulls and cormorants) that make their homes here.
