Gémeos Grandes

Dive the Algarve with SUBNAUTAA collection of 40 artificial reefs created by the IPIMAR in 2000, placed in four rows, between the João de Arens beaches and the barra da Ria de Alvor, at depths of 18 to 35 meters, to be used as a resource for the creation and protection of juveniles of various species characteristic of the zone.

Along the reefs, a gradual increase has been observed in the fauna of the area, confirming their usefulness.

The Gémeos Grandes (Greater Twins) consist of three blocks of concrete resting on the sand, at a depth of 30 meters, spaced 30 to 40 meters apart, and joined together by a cable guide.

There is a wide variety of sea life, however, the most common species are morays, congers and zebra sea breams. It is important to control the diving time, as the site can reach depth of up to 35 meters in the deepest part, at certain times of the year.
