Visitors to the Cabo de Gata-Nijar Natural Park can discover some of the best seabeds in the entire Mediterranean, which are ideal for diving. The 12,000 hectares of marine reserve, up to a marine mile from the coast, with more than a thousand species of flora and fauna, are the authentic hidden treasures of Cabo de Gata. The rocky composition and the clarity of its waters, up to 18-20 meters visibility in optimal conditions, make this area an authentic paradise for contemplative and photographic diving. Remember that underwater fishing is totally prohibited, as is the use or possession of instruments that can be used for that purpose.
In some areas, such as Monsul or Rodalquilar, we can enjoy this unique beauty at just one meter deep. However, it is from 5 meters deep where the most experienced divers can enjoy a unique show.
The seabeds of the Natural Park are very varied, finding sand bottoms, rock bottoms and bottoms covered by the meadows of Posidonia Oceanica; where we can find various different marine species in each one of them.
On the sand bottoms we find a great variety of marine phanerogams that are more than algae, theseare true plants with flowers, as well as rich fauna camouflaged among the sediments: Donax trunculus, Chamelea gallina, spiny dye-murexs, cuttlefish, octopus, sea urchins, starfish, crabs and a plethora of fish among which the red mullet, the sand steenbras and the Mediterranean rainbow wrasse stand out.
On the rock bottoms we find at a shallow depth, vegetation cover full of algae, sponges, madrepores, anemones and false corals. We will also find annelids, molluscs, sea urchins, starfish and fish such as the cardinalfish, the shi drum, the ornate wrasse and the common two-banded sea bream. At greater depth we can find groupers, moray eels and red scorpion fish, which find refuge among the cracks in the rocks.
And finally, in the meadows of Posidonia Oceanica, among the authentic gems of this Natural Park, we find the spawning areas and refuges of abundant fish, crustaceans and mollusks.
The Posidonia Oceanica prairies enrich the biodiversity of the marine environment and guarantee its maintenance by providing, directly or indirectly, large quantities of organic material usable as food by countless living beings. These meadows can be observed from 15 meters deep, when entering the open sea.
