Roca Roja

The ridge appears a few metres below the mooring line, its crest at around 14 m. Head deep first. The rocky bar (barra) slopes toward 30 m where it meets sand and loose rocks, and the north-facing wall comes alive with red and yellow gorgonians between 20 and 30 m. Cracks split the rock in every direction. Morays watch from the openings. Conger eels coil deeper inside. Octopuses sit in the sandy patches at the base. Turn back and ascend along the ridge at 16 m, crossing through one of the two small canyons that connect the coastal side to the seaward face. The formation narrows and rises. At 9 m, the shallowest peak. Stop here. Look into the blue. Barracuda schools hold position off the crest, silver against open water. The whole site extends far enough that navigation choices determine what you see — three different centres run three different routes on the same formation.

Roca Roja splits cleanly into two dives stacked on top of each other. The deep route is a gorgonian wall dive with crevice life dense enough to fill a macro photographer's memory card. The shallow route is a pelagic encounter with barracuda. No other Palamós site delivers both in a single profile. The ridge is wide enough that currents rarely build, and the multilevel layout means OW and AOW divers on the same boat each get a satisfying dive without compromise. Multiple centres from three towns run trips here, which means the site has been well mapped. Several offer thematic eco-guided routes: nudibranch macro dives, barracuda behaviour observation, cephalopod hunts. Half a mile offshore, out of sight of the beach crowds, it has the feel of a committed open-water dive — the reddish rock on the surface is what the helmsman uses to find the mooring.

Start deep, finish shallow. Barracuda concentrate at the shallowest peak, so ending there puts the best pelagic encounter at the point where you still have time. Bring a torch for the crevices where nudibranchs, scorpionfish, and small lobsters hide in shadow. Gidive recommends crossing through the ridge's cracks to the seaward side at half tank. The boat ride from Palamós is 20 minutes south, passing Sant Antoni de Calonge and the 16th-century Torre Valentina on the coast. From Platja d'Aro, 15 minutes. On days when the Tramuntana is blowing from the north, the open-sea exposure grounds this site more often than sheltered nearshore dives — centres may redirect to closer alternatives.
