Medes Islands

The Medes Islands are widely regarded as one of the finest diving destinations in the entire Mediterranean. This small, craggy archipelago of seven limestone islets sits just half a mile off the Costa Brava coast near the town of L'Estartit in Catalonia. Protected as a National Marine Park since 1990, the 52 acres of archipelago and 1,262 acres of surrounding protected sea have produced an underwater environment of extraordinary richness. What strikes you first upon descending is the sheer abundance of life. The limestone walls are blanketed in colour: blue and yellow gorgonian sea fans sway in the gentle current, red coral clings to overhangs, and dense colonies of sponges and bryozoans fill every gap. Swim-throughs and tunnels carved through the soft limestone create dramatic passages where shafts of light pierce the darkness, illuminating clouds of cardinalfish and damselfish. The undisputed stars of the Medes are the dusky groupers. These magnificent fish, some weighing over 20 kilograms, have grown so accustomed to divers after decades of protection that they approach within centimetres. It is not unusual to have several groupers escorting you throughout an entire dive. Schools of barracuda swirl overhead, while moray eels coil in every other crevice. Lucky divers may spot eagle rays gliding past the deeper walls, and dolphins are occasionally seen from the boat. The variety of dive sites suits all experience levels. Shallower reefs at 10-15 metres are perfect for Open Water divers, while Pedra de Deu offers advanced divers a vast wall covered in gorgonians descending to 44 metres. The Dolphin Tunnel, a dramatic swim-through, is a favourite among underwater photographers. Visibility averages 15-20 metres during summer, though autumn days can bring crystal-clear 25-metre conditions. The boat ride from L'Estartit harbour takes just ten minutes, and multiple dive centres operate daily trips throughout the season. The Medes Islands prove that decades of committed marine protection can transform a degraded Mediterranean coastline into a thriving underwater paradise that rivals tropical destinations for pure biodiversity.
