Diving in Illes Medes

Forty years of no-take protection have turned this seven-islet archipelago a kilometre off L'Estartit into the Spanish Mediterranean's clearest proof of recovery. The story shows up in the fish. Large dusky groupers hold territory at virtually every island site from five metres down to the deep walls, often approaching divers rather than drifting away. 2024 trip reports still name the "big black mero" and schooling barracuda as the defining image of the reserve.

The archipelago is the submerged continuation of the Montgri massif: limestone ridges carved into tunnels, caves, vertical walls, pinnacles and boulder fields. La Vaca cuts a thirty-metre tunnel through Meda Gran, backlit by daylight with a resident grouper at the entrance. The Dofi complex crosses Meda Petita through chambers, short caves and a cathedral-vaulted passage at eighteen to twenty metres, carpeted in red coral. On the outer faces, Pedra de Deu and Pota del Llop drop past forty-five metres through blue and yellow Paramuricea fields. Sheltered options like El Salpatxot, Embarcador del Frances and Cova de la Reina keep Open Water divers inside the same ecosystem.

The daily diver quota shapes every visit. Book in advance, especially for summer weekends and the signature rotations of La Vaca, the Dofi pair and Carall Bernat. Park permit is 5.30 EUR per dive per diver in 2026, collected through your centre along with the mandatory eco-briefing. Bring certification at second-class or Advanced Open Water level, federative licence or private insurance, and a good dive light for the tunnels.

Local centres cluster in L'Estartit with one operator in L'Escala. Pricing is consistent: single-dive all-in roughly 43 to 65 EUR, Open Water courses 420 to 459 EUR, park tax a pass-through. Summer premiums run ten to fifteen percent; own-equipment tiers save twenty to thirty EUR on a double dive. Several operators carry CETS and ISO 14001 certifications promoted through the park's eco-briefing programme. Plan for 5mm hooded as the summer suit minimum. A thermocline from twenty metres down drops water temperature sharply even in August. Spanish regulars recommend September over August for warm water, better visibility and thinner crowds. The Montgri coast supplies try-dive training and a fallback when island quota is full or the wind turns east.
