Arrecife Barrera de Posidonia (Lit: “Posidonia Great Barrier Reef”) is located between Roquetas de Mar and Aguadulce. This reed is considered to be a Natural Monument dur to the lack of Posidonia reefs that can still be found on Mediterranean Coasts. Apart from that, it is the only one reed that can be found in Andalusia.
This marine plant, called “Posidonia Ocenanica”, has got very peculiar characteristics like its long green leaves in the form of strip that may reach 1 meter long. This makes them to be united altogether on the ground by a complex structure of stalks and little roots that colonize the seabed.
The reed serves as a refuge for more than 800 species which includes animals and vegetables. It is also a breeding area for a big number of species like gilt-head breams, Mediterranean sea basses or red mullets, among others. Besides, this area is the perfect place to go snorkeling for observing the local fauna and flora.
