Cabo de Gata (Almeria). Groupers, conger, pollock, moonfish, starfish, sponges, anemones and other species enjoy their natural habitat at 20 meters deep. Prying eyes can immerse themselves in Cerro Negro, a 17 meters underwater rock area where diving is practiced. Another good place to dive is Piedra Las Negras, a very close spot there 32 meters deep.
