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

75+

Below this we'd send you somewhere easier first.

Recommended certification

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

“Accessible to most certified divers with basic open water skills.”

What will challenge you

→Moderate currents. Expect to drift — this is not a skill-builder site for a first trip after certification.
→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.
→Variable visibility
→Navigation in low viz

What will surprise you

→Thermoclines can drop water temp by 4°C between the surface and depth. Your wetsuit choice should match the minimum, not the average.

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.
