Clot del Boc

A tunnel-and-cave entrance near 12 metres and the park's own shallow marked point near 17 metres sit at the top of a rocky ridge that runs south from in front of Cala Jòncols, part of Cap Norfeu's submerged mountain range.1 Past that shelf, the wall and slope continue over rock mixed with sand and patches of red coral. Two operators that dive the fuller route follow the same ridge down to a working maximum between 30 and 35 metres; a separate account of this exact site instead describes a shallower drop-off, from about 5 to 20 metres, ending in a canyon.

A tunnel near the base of the wall opens into a small cave at 12 metres, where large schools of sardines gather. The park's own species panel for this point is headed by the spiny lobster, alongside dusky grouper, seahorse, common octopus and the violet nudibranch Flabellina affinis.1 Dusky grouper works this stretch of rock at every depth divers describe here, from the shallow shelf to the deeper ridge. Both operators that dive here frame the site as part of the Cap Norfeu circuit, though neither the site's own sheet nor the park's separate index states which of the park's three marine reserves this point falls under.

Roses Sub, based in Roses, and Sotamar, based in Cadaqués, are the two operators confirmed to run trips here. The shallow shelf near the tunnel stays within Open Water limits; the deeper route some operators run past 30 metres needs Deep Diver training. The site's own eco-briefing sheet asks divers to stay 1.5 metres clear of both the reef and the seabed, and to leave fish, invertebrates and any fishing gear untouched. Hold that same buoyancy discipline through the tunnel: the sardines sheltering inside it are covered by the same no-touch rule as the rest of the point. Independent divers must give the park prior notice and stay within its cap, applied per boat, not per diver: six dives a day, thirty a week, a hundred and twenty a year.2
