Natural Park of Penyal d'Ifac (Valencian: Parc Natural del Penyal d'Ifac, Spanish: Parque Natural del Peñón de Ifach) is a natural park situated in Calpe (Calp), in the autonomous community of Valencia, Spain.
The Penyal d'Ifac is a massive limestone outcrop emerging from the sea and linked to the shore by rock debris. It is home to numerous rare plants, including a number of endemic species, and over 300 species of animals, and a nesting site for colonies of sea birds and other birds.
Rising to 332 metres high, the rock is a striking visual feature of the Mediterranean coastline. Historically it was known to the Phoenicians as the Northern Rock, to distinguish it from its southern counterpart, the Rock of Gibraltar.
Behind Penyal d'Ifac is a large lagoon cut off from the sea by strips of sandy beach and extending inland to the coastal mountains. The wetland area around the lagoon is all that remains of the formerly much more extensive wetlands of the Marina Alta.
A protracted campaign to protect the site's unique natural diversity led to the area being granted natural park status in January 1987. With an area of 45 hectares, it is the smallest natural park in Spain, possibly in Europe. The park ranges from sea level to an altitude of 332 metres at the summit of the rock (penyal in Valencian, peñón in Castilian).
From the top of the rock there are views over the surrounding villages and countryside and on a clear day as far across the sea as Ibiza in the Balearic Islands.
