The Medes Islands reserve is one of the Mediterranean's most successful marine protection stories. Groupers the size of labradors approach divers here, and the tunnels and caves of Carall Bernat create dramatic swim-throughs filled with red coral and gorgonians. Forty years of protection have made this a Mediterranean showpiece.

Honest reality check

What your dive shop won't tell you

The minimum certification printed on a brochure is the legal floor, not the honest recommendation. Here's what we actually think you should bring to this site.

Recommended logged dives

70+

Below this we'd send you somewhere easier first.

Recommended certification

Advanced Open Water + Drysuit specialty

“What a Med reef looks like after 40 years of protection. Grouper are absurdly friendly.”

What will challenge you

→Moderate currents. Expect to drift — this is not a skill-builder site for a first trip after certification.
→Recreational limit of 40 m is reachable here (max depth 40 m). Gas planning and NDL tracking matter.
→Cold water — 13°C at the coldest. Drysuit recommended; wetsuit divers will be genuinely cold past 30 minutes.
→Wreck penetration requires Wreck specialty training at minimum, and often decompression planning. Don't improvise inside.
→Limited permits per day in summer. Book ahead.

What will surprise you

→Short dive season — only 2 months worth going (May, October). Book well ahead or miss it.

Shoot here

Photography brief

Subjects are only half the shot. A perfect macro site is useless in a three-knot drift, and a wide-angle dream is useless at 35 m with a murky ceiling. These are the conditions, not the hype.

Recommended kit

→Dedicated video light for dark wreck interiors; don't rely on strobes alone
→Cold-water housing — condensation is a real issue below 18°C, bring silica packs
