Mauritius
Mauritius rings a volcanic interior with lagoon after lagoon, and the diving happens where those lagoons drain: passes, outer slopes, and a set of deliberately sunk wrecks. Flic en Flac's Cathedral cavern, the scorpionfish-carpeted Rempart Serpent, and the trawler wrecks off Trou aux Biches anchor the west and north coasts. It is a comfortable, family-friendly dive destination rather than a big-animal one — with humpbacks passing in austral winter.
ここでダイビングする理由
The west coast between Flic en Flac and Le Morne holds the marquee terrain: the Cathedral, a cavern and arch cut into the fringing slope where shafts of light drop onto soldierfish and lobster, and Rempart Serpent, a low rubble ridge with one of the densest concentrations of scorpionfish, stonefish, and morays you will find anywhere — a macro dive that rewards slow, careful eyes. The north adds structure by scuttling: the Stella Maru off Trou aux Biches and the Djabeda near the dramatic islet of Coin de Mire both sit upright at recreational-to-deep-recreational depths, well colonized and easy to circle. Lagoon shallows suit training and snorkeling, while passes such as St Jacques in the south run proper drift dives when the tide moves. Mauritius pairs all of it with direct long-haul flights, good-value resorts, and enough topside — Chamarel, Black River Gorges, street food in Port Louis — to fill a two-week trip where diving is the anchor, not the whole itinerary.

October-December and March-May bracket the best mix of calm seas and warm water. January-February carry cyclone risk; June-September is cooler and windier, favoring the sheltered west coast, with humpback whales offshore.

アクセスと宿泊
アクセス: Direct flights arrive from Europe, Africa, Asia, and Australia; drive times from the airport run about an hour to Flic en Flac and 1.5 hours to the north-coast dive hubs.
宿泊先: Flic en Flac and Tamarin serve the west-coast sites; Trou aux Biches, Pereybère, and Grand Baie serve the north. Apartments and aparthotels are plentiful alongside the resorts.
費用: Diving is mid-priced for the Indian Ocean; hotel dive centers charge more than independent operators in Flic en Flac and Trou aux Biches.
ダイビングの合間に: Black River Gorges hiking, the Chamarel coffee and rum region, Port Louis markets, kitesurfing at Le Morne, and whale-watching in season.
スノーケリング: Lagoons at Blue Bay, Trou aux Biches, and Le Morne offer easy, shallow snorkeling in mostly calm water.
安全性と実用情報
危険生物・リスク: Cyclone swells in late summer, surge in caverns and on shallow ridges, boat traffic inside busy lagoon passes, and abundant well-camouflaged stonefish — control your buoyancy and your hands.
Wear full exposure protection and watch where you settle; stonefish envenomation is a real local risk. Deeper wrecks such as the Djabeda warrant advanced certification and a conservative profile.
最寄りの再圧タンク施設: Hyperbaric provision on the island has varied over the years — confirm current arrangements with your operator; emergencies go through local EMS and DAN.
