Rikoriko Cave — the world's largest sea cave — is the centerpiece, but the arches, walls, and kelp forests host 125+ fish species. Jacques Cousteau rated it one of the world's top 10 dive sites.

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

100+

Below this we'd send you somewhere easier first.

Recommended certification

Cavern Diver minimum. Full Cave certification for anything past the daylight zone.

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 — 14°C at the coldest. Drysuit recommended; wetsuit divers will be genuinely cold past 30 minutes.
→Overhead environment. Standard recreational training does not cover you past the entrance. People die here doing what they'd do on an open reef.
→Wreck penetration requires Wreck specialty training at minimum, and often decompression planning. Don't improvise inside.
→Nearest hyperbaric chamber is ~200 km away. Evacuation is slow. Dive conservative profiles and get DAN insurance before you fly.

What will surprise you

→Short dive season — only 2 months worth going (February, June). 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

What this site will teach you

The dives that made you a better diver are the ones that made you uncomfortable for the right reasons. Here's what this site will quietly train you for.

Drysuit + thermal management
intermediate
Diving in 14°C water forces you to manage trim, buoyancy shifts on ascent, and task loading in thick gloves. Cold-water skills pay off every time you dive outside the tropics.
Overhead environment awareness
advanced
Cavern-zone diving teaches line awareness, light discipline, silt management, and the habit of always knowing where the exit is. These are the fundamentals of every overhead dive you'll ever do.
Wreck penetration fundamentals
advanced
Line laying, gas planning for the way back, and silt-out response. Learn it on a site with clear-water wrecks before you try it in darker water.
Deep profile discipline
advanced
Max depth 40 m puts you at the edge of recreational limits. You'll build NDL tracking instincts, gas reserve management, and safety-stop discipline you can't get on 18 m reef dives.
