A Cap Norfeu wall dropping from a government-marked 24-26 m shelf to a tech-grade 45-48 m base, with a possible seahorse ground and dusky grouper.
Last updated September 2026

Rock and sand lead into a wall off Cap Norfeu, where a mix of bare rock and coralligenous growth holds until sand takes over again at depth. The park's own eco-briefing sheet marks a shallow shelf here between its -24 and -26 metre contour lines;1 beyond that shelf, the wall continues to a base near 45 to 48 metres. Dusky grouper and a resident skate work the wall itself, while the open water off the rock draws barracuda and, less often, tuna.
Six named species crowd this single stretch of rock, from a possible seahorse ground to a resident skate and a violet nudibranch.1 The wall itself offers two genuinely different dives under one name: a shelf that sits inside Advanced Open Water limits, and beyond it a technical-only stretch bottoming out between 45 and 48 metres.
Currents at this point are occasional, not constant: plan for a possible push and be ready to turn the dive early if it builds. Independent boats must notify the park before diving here and stay within its cap: six dives a day, thirty a week and 120 a year, applied to the boat, not to each diver.2 The site's own eco-briefing sheet layers a further rule on top of the park's standing no-touch and no-fishing ban: keep 1.5 metres clear of both the wall and the seabed.1 Treat the two published depths as two different dives, not one profile with a margin of error: plan the shallow shelf on its own terms, and treat anything past it as a separate technical dive with its own gas and decompression plan.
What makes this dive site stand out.
A shelf near 24 to 26 m gives way to a route reaching 45 to 48 m
Coordinate, six species and buoyancy icons come from the park's own sheet
Named independently by both the government sheet and a local operator
Inside one of the park's three marine reserves with a no-touch, no-fishing rule
42.2388°N, 3.2538°E
Advanced Open Water covers the shallow 24-26 m shelf; the wall's deeper base needs a technical certification.
Summary
Moderate at the shallow shelf, expert-only once the wall runs past 40 m.
