Dive briefing

AI-generated

Conditions are excellent with a calm morning and raw sea state of 0.2–0.5m. You'll drop through the chimney into the arch in ideal light, with water temperature at 29.3–29.8°C. The site is intermediate-level and protected today, though remember it closes out under northerly swell.

Divers commonly log marbled crabs and a strong population of wrasses here — ornate, Mediterranean rainbow, and their painted comber cousins. European parrotfish, white sea bream, peacock blennies, and Mediterranean damselfish are often recorded in the shallows. Plan your bottom time around the depth range of 5–30 metres.
