Grosa Island

Grosa Island and La Manga.

The Grosa island is a Spanish island in the municipality of San Javier in Region of Murcia. It is the only island in the environment of the Mar Menor which is outside of it. It is a very steep volcanic cone that exceeds 90 meters, at a distance of 2.5 kilometers north of La Manga del Mar Menor.
The island was a refuge for Berber pirates until the eighteenth century.
Noted for its botanical and ornithological richness: it nesting petrels, cormorants, peregrine falcon, Audouin's gull. It has a pier and there were only buildings associated with military activities. The island was a military zone until 2000, when it was ceded to the Murcia to carry out activities related to the environment (until then it was the place of training special units of combat divers and bomb disposal Dive Center of the Navy).
It forms a perfect volcanic cone, but like most eroded volcanoes at Region of Murcia.
