Located near the port area
The seven islets of the Illes Medes, scattered just one nautical mile off L'Estartit, shelter over 1,300 marine species within 511 protected hectares. Designated a marine reserve in 1983, the archipelago transformed from overfished rock clusters into the Mediterranean's densest concentration of grouper, octopus, and coralligenous formations. Visibility routinely exceeds 20 meters between May and October, when warm currents stabilize and plankton blooms subside. Medes Islands snorkeling reveals what four decades of protection achieve. The Tascó Petit channel between Meda Petita and Carall Bernat hosts schools of gilt-head bream and Mediterranean barracuda that trail snorkelers through kelp forests and Posidonia meadows. The underwater cliffs of Medallot drop 50 meters, their upper shelves accessible to surface swimmers who peer into crevices where moray eels and red starfish anchor against the current. Gorgonian fans, rare elsewhere in the western Mediterranean, colonize the northern faces where Atlantic swells sweep nutrients through the reserve. Cave exploration marks the signature feature of guided tours departing L'Estartit harbor. The Cova de la Vaca, a sea-level cavern on Meda Gran, allows swimmers to drift through cathedral-like chambers where light refracts off rippling ceilings and painted combers hide in shadowed alcoves. The reserve's strict zoning permits only licensed operators to approach within 80 meters of the islands, a regulation that preserves the ecosystem while concentrating visitor access through monitored channels. The €3.05 conservation tax, collected at departure points and dive centers throughout L'Estartit, funds ranger patrols and mooring buoy maintenance that prevent anchor damage to the seabed. Morning departures between 9:00 and 12:00 align with slack tides and offshore breezes that flatten the surface, conditions particularly stable during summer months when the tramontana wind loses its spring ferocity. Glass-bottom boats supplement snorkeling excursions, offering surface views for non-swimmers while underwater explorers descend to investigate rock gardens and sandy patches where cuttlefish camouflage against the Mediterranean floor.
"Four decades of protection transformed the Medes from overfished rocks into the Mediterranean's densest marine sanctuary."
A step-by-step walkthrough of the visit — what you'll see, how long each stage takes, and the details that matter.
You board at L'Estartit harbor as morning light slants across the Costa Brava coastline, the seven Medes silhouettes growing distinct as the boat cuts eastward through calm water. The skipper anchors off Tascó Petit, and you slip over the gunwale into 22-degree water, mask sealed, snorkel cleared. Below, the rocky slope descends through bands of green and blue, Posidonia grass swaying in the gentle current. You kick toward the channel between Meda Petita and Carall Bernat, where schools of salema porgy part around you and regroup in your wake. A grouper the size of a small dog watches from beneath a ledge, unafraid, its mottled brown bulk motionless against the stone. You follow the guide toward the Cova de la Vaca, ducking into the sea cave's mouth where daylight filters through submerged arches and the water glows turquoise against white rock. Inside, you float in the vaulted chamber, sound muffled, breathing steady, gorgonians clinging to the walls where wave surge has carved the limestone smooth. Outside again, you drift over coral encrustations and anemone clusters, the reserve's protection visible in every crevice thick with life, before the recall whistle signals the return swim to the boat.
The reserve is accessible 24/7, though local boat centers operate based on weather.
