Juan Fernández Islands Diving — Chile

The Juan Fernández archipelago — inspiration for Robinson Crusoe — lies 670km off Chile in the Pacific, with over 90% marine endemism. The endemic fur seal population has recovered spectacularly and now playfully joins divers. Getting there is expensive and weather-dependent, but the uniqueness is unmatched.

Dive Insurance

Dive insurance is essential. Standard travel insurance often excludes scuba diving. We recommend DAN (Divers Alert Network) for comprehensive dive accident coverage.

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
80+

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.
  • →Recreational limit of 40 m is reachable here (max depth 35 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.
  • →Overhead environment. Standard recreational training does not cover you past the entrance. People die here doing what they'd do on an open reef.
  • →Nearest hyperbaric chamber is ~670 km away. Evacuation is slow. Dive conservative profiles and get DAN insurance before you fly.
  • →Variable visibility
  • →Deep profiles

What will surprise you

  • →Permit-restricted access. Daily cap: 15 divers. Book 6+ months ahead through a licensed operator.
  • →Juan Fernández Islands has more marine life variety than most divers expect
  • →Local operators know spots the guidebooks miss

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

  • →Two independent light sources minimum; video lights beat strobes in caverns
  • →Cold-water housing — condensation is a real issue below 18°C, bring silica packs
