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.
Below this we'd send you somewhere easier first.
“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.
- →Cold water — 4°C at the coldest. Drysuit recommended; wetsuit divers will be genuinely cold past 30 minutes.
- →Nearest hyperbaric chamber is ~300 km away. Evacuation is slow. Dive conservative profiles and get DAN insurance before you fly.
- →Variable visibility
- →Navigation in low viz
What will surprise you
- →Short dive season — only 4 months worth going (June, July, August, September). Book well ahead or miss it.
When to dive it
Every dive shop gives you this briefing at 7am. We just wrote it down. Tidal dependency: slight. Optimal window: First light to 11am for best visibility..

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
- →Cold-water housing — condensation is a real issue below 18°C, bring silica packs

Budget decision guide
Choose Budget if you prioritize dive count over comfort — hostels and shore diving maximize bottom time per dollar. Choose Mid-range for the best balance of comfort and value — most divers land here. Choose Splurge for premium operators, private guides, and top-tier accommodation — worth it for special trips or non-diving partners.
Flights priced round-trip from a major US hub. Figures are per person on a shared room. Solo travelers add ~30% to accommodation.
