Dofí Nord

A system of interconnected tunnels crossing Meda Petita island, Dofi Nord offers three distinct routes from a single mooring. The most popular starts with the short dolphin tunnel -- roughly 30 metres of wide, naturally lit passage that exits on the south face where the small dolphin statue sits at 12 metres. From there, divers with sufficient certification can loop back through the long tunnel, a 65-to-90-metre passage that drops to 25 metres and opens onto the north wall through gorgonian-framed mouths. Between the two tunnels lies La Catedral, a vaulted chamber where the calcareous rock amplifies the filtered light from above. For those who prefer to stay in open water, the L'Herminia route follows the outer wall over irregular rocky bottom populated by groupers, brown meagre, and scorpionfish.

Dofi Nord is the only site in the Illes Medes where divers choose their difficulty in real time. The short tunnel is wide enough for two divers abreast and lit by natural ceiling openings that produce the shafts of light the site is famous for -- an Open Water diver's introduction to overhead environments with none of the commitment of technical cave diving. The long tunnel, by contrast, narrows and darkens, its entrance flanked by large gorgonian fans and its cavities home to slipper lobsters, conger eels, and forkbeards that have claimed the permanent shadow. Outside, the walls host one of the most abundant red coral colonies in the Medes at a mere 12 metres -- shallow enough to spend real time with on a safety stop.

Bring at least one dive torch and ideally two -- the long tunnel has sections with no natural light. Buoyancy discipline matters more here than at any other Medes site: the cavern ceilings are fragile, silt reduces visibility quickly when disturbed, and accumulated macro bubbles from hovering divers damage formations over time. Minimise time stationary under enclosed ceilings. For photography, wide-angle lenses capture the tunnel light shafts best; the contrast between the bright ceiling openings and the shadowed walls is the signature composition.
