Reunion Island Diving — France
Reunion's volcanic geology creates dramatic underwater topography — lava tubes, arches, and caverns that you won't find on coral islands. The west coast's lagoon-protected reefs are the primary dive area, with healthy marine life in a marine reserve. Being a French overseas territory means European-standard dive operations.

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.
“Volcanic lava tube diving plus humpback whales. Unique Indian Ocean destination.”
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.
- →Wreck penetration requires Wreck specialty training at minimum, and often decompression planning. Don't improvise inside.
- →Shark risk is real — fatal bull shark attacks on surfers. Dive with reputable ops in organized groups.
What will surprise you
- →Thermoclines can drop water temp by 7°C between the surface and depth. Your wetsuit choice should match the minimum, not the average.
- →Short dive season — only 2 months worth going (June, November). Book well ahead or miss it.

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
