Diving in Cabo de Palos

A small fishing harbour under a lighthouse, and behind it a chain of submarine mountains that surface as the Islas Hormigas. Boats run the same short distance from the quay every morning. Bajo de Dentro rises to 3 metres from a 40-metre base, a single canyon splits the pinnacle north-to-south, and resident groupers the size of small dogs approach without caution. This is the dive most visitors do first, and the reason the reserve is worth the permit paperwork. Piles 1 and Piles 2 sit to the west, 75-metre ridges between 8 and 27 metres. Their signature experience is the summer barracuda schools that circle both pinnacles in July and August. Bajo de Testa, closer to the coast and more sheltered from current, is the gentle introduction. Beyond the reserve boundary, the 1946 Naranjito rests upright at 26-40 metres. Penetrable, colonised by conger eels and groupers, it is the area's iconic wreck and sits outside the permit system. Deeper still, at Bajo de Fuera, three more wrecks lie within the daily 25-diver cap: the 1906 SS Sirio between 35 and 65 metres, the SS Minerva, and the Nord America. Below the lighthouse, Escalerita and the other calas start at 2 metres with tunnels and arches, usable for try-dives and bad-weather days. Reserve spillover keeps even these shallow sites rich. The trip profile most divers settle into is two dives from the same boat by 2 PM, back at the harbour for lunch.

September and October. The forum consensus is unambiguous: same marine life as summer, visibility at its yearly peak, and noticeably fewer divers. July and August deliver peak biomass but also catamaran loads, rushed 40-45 minute dives, and fully booked centres. Book weeks ahead if summer is unavoidable. Every reserve dive goes through an authorised centre. Reported pricing clusters within a narrow band (45-50 EUR for coves, 50-55 EUR inside the reserve, 60-65 EUR for the Naranjito), a pattern local divers traced to a mid-2010s price agreement that has held in the years since. Bajo de Fuera demands B2 certification, 15 days advance notice, insurance, and a medical certificate. Summer thermoclines drop ten degrees between surface and 20 metres, so carry more neoprene than the air temperature suggests. Murcia International Airport sits 40 minutes by car; Alicante is 90 minutes. A car is essential for gear logistics. Centres split on guide policy and on seasonal opening, so confirm both when you book.

Submarine mountains (bajos) of the Islas Hormigas archipelago rise abruptly from 40-60m to within metres of the surface. Persistent currents have sculpted walls, ledges, and canyons into pinnacles that act as natural aggregation points for pelagic fish.
