Diving in Seychelles
The Seychelles scatter granite across the Indian Ocean like nowhere else, and that geology defines the diving: rounded boulder mounds draped in soft coral, swim-throughs and canyons, and reef fish swirling where tropical islands elsewhere would offer flat coral shelf. The inner islands — Mahé, Praslin, La Digue — provide easy day-boat diving with turtles, rays, schooling snappers, and seasonal whale sharks, while remote outer atolls see only the occasional expedition. Coral here was hit hard by past bleaching events, and recovery varies site to site; the granite topography and fish life carry the show regardless. It is an unabashedly premium destination where diving usually shares the trip with beaches that live up to their photographs.
The registry's destination covers the inner-island scene. Mahé bases reach sites like Shark Bank and wrecks off the northwest coast; Praslin and La Digue operators dive granite reefs such as those around Ave Maria and Marianne; marine national parks (Sainte Anne, Baie Ternay) shelter easy reef dives. Outer-island expeditions exist but sit beyond typical itineraries.
Signature experiences: Weaving through granite canyons furred with orange soft coral; hawksbill turtles working the reef unbothered; seasonal whale-shark encounters off Mahé; eagle rays over sand channels; a La Digue bicycle-and-beach afternoon after a two-tank morning.
Seasons: The calm inter-monsoon windows — roughly March-May and October-November — bring the stillest seas and best visibility. The southeast trades (June-September) cool the water and stir chop; the northwest season around the turn of the year is warmer and wetter. Whale-shark sightings have historically clustered in the later-year window but vary by year.

The practical file
Getting there: Fly to Seychelles International (SEZ) on Mahé via hubs such as Dubai, Doha, Istanbul, Addis Ababa, or Nairobi. Praslin is a short domestic flight or fast ferry from Mahé; La Digue is a ferry hop from Praslin.
Entry & visas: The Seychelles issue a visitor's permit on arrival for most travelers rather than requiring an advance visa, with electronic pre-arrival formalities in use; verify current requirements before travel.
What diving costs: Expect roughly EUR 100-160 for a two-tank boat day, with island lodging pricing from expensive guesthouses to very expensive resorts; overall trip costs rank among the Indian Ocean's highest even before flights.
Language: Seychellois Creole, English, and French are all official; English works everywhere in the dive industry.
Tipping: Tipping is welcomed but not obligatory; 5-10 percent or a crew tip after a good dive day is typical, and service charges appear on many bills.
Travel safety: The islands are safe and easygoing; petty theft from beaches and unlocked rooms is the main nuisance, so keep valuables secured. Sea conditions in the trade-wind months can make crossings lumpy, and some sites carry current — standard briefing-and-DSMB diving rather than a hazard story.
Recompression cover: Hyperbaric capability has been maintained on Mahé, but availability changes; confirm the current emergency pathway with your operator and route incidents through local EMS and DAN.
