Tascó Gros is a dive site located on the south part of Medes Islands, Costa Brava, in a sheltered area. The region abounds in marine life, with frequent sightings of Mediterranean barracudas and common dentex. Octopus, moray eels, giant groupers, eagle rays, damselfish, nudibranchs, sea perches, and sea slugs can also be spotted here.
Together with its twin islet - Carall Bernat, Tascó Gros forms a vertical wall filled with red and white gorgonians. The wall ends with a platform formed by blocks of rock, with numerous cavities that offer shelter to the region’s marine fauna.
