Mahe & Praslin Diving — Seychelles
The Seychelles' inner islands offer diving among massive granite boulders — a unique underwater topography found nowhere else. Whale sharks visit from October to January, turtles are year-round residents, and the reefs recovered impressively after the 1998 bleaching event. The above-water scenery is just as spectacular.

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

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.
What will challenge you
- →Moderate currents. Expect to drift — this is not a skill-builder site for a first trip after certification.
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.
Recommended kit
- →General reef kit — mid-range wide or a 60mm macro depending on the specific site
