El Reggio

The mooring buoy line drops to the stern at 23 metres, and the wreck materialises out of the reduced visibility — a massive dark shape on the sandy bottom. From the stern, the hull stretches forward for over a hundred metres, its surfaces colonised by sponges and encrusting life after three decades as an artificial reef. Following the hull forward, the structure narrows and breaks into separated sections before the bow appears at 35 metres, detached from the main body of the ship. Groupers and scorpionfish have claimed the wreck's cavities. At these depths, the dive computer becomes the constant companion — bottom time disappears quickly, and the temptation to explore just one more section is the hazard that makes El Reggio a site demanding discipline as much as certification.

Every other dive in the Estartit area is natural reef, cavern, or wall. El Reggio is the sole wreck — a 122-metre train ferry that once shuttled rail carriages to Italy, deliberately sunk in 1991 and now the largest artificial reef on the Costa Brava. The scale is what impresses: at 122 by 17 metres, this is not a small boat on sand but a genuine ship that cannot be circumnavigated in a single dive. After 30 years in protected waters, the wreck has developed its own ecosystem distinct from the surrounding reef sites. The reduced visibility (5-15 metres versus 10-25 metres at the islands) creates a different atmosphere entirely — wreck features appear and disappear in the haze, giving the dive an exploratory quality absent from the clear-water island sites.

Plan your route before descending — stern exploration or bow push, not both. The stern at 23 metres is the natural starting point and the shallowest section; the separated bow at 35 metres demands more air and brings you closer to no-decompression limits. Nitrox 32% is strongly recommended for either route. Visibility of 5-15 metres means a torch is essential, not optional, and maintaining orientation relative to the mooring line prevents the disorientation that a 122-metre wreck in murky water can produce. Most centres pair El Reggio with the adjacent Cap Castell for a two-dive morning — the shallow wall makes an ideal decompression-friendly second dive after the deep wreck.
