Situated some 805 kilometres (530 miles) east of Madagascar and around 200 kilometres (130 miles) south-west of Mauritius lies La Réunion in the Indian Ocean. Reunion is a French island that stands out from all the others. It’s an island where you can dive prestige reefs, walk in valleys full of waterfalls and visit an active volcano all in the space of one day. It is a mountainous island and is known worldwide for its hiking trails, mountain bike trails and paragliding.

Volcanic in origin with one volcano, “Piton de la Fournaise”, still active this island rises 3 069m straight out of the ocean and has thousands of valleys surrounding its active volcano. The entire island is covered in mountains and the waters provide some of the best dive sites the Indian Ocean has to offer.
The volcano, “Piton de la Fournaise”, is a major tourist attraction and is located within the Réunion National Park, a UNESCO World Heritage site. It sits 2 632m above sea-level and is active with regular eruptions. These volcanic activities provide spectacular viewing and what makes it even more amazing is that you can safely approach the lava flows from previous eruptions.
Geologically, Reunion Island is relatively young and consequently its lagoons are small and not very deep. The island however, rises from deep water and is a magnet for whales, whale sharks and other pelagic animals. Fed by deep ocean currents, it boasts healthy reefs that teem with colourful fish. The coral forms a discontinuous reef of about 15km to the west and south of the island.The Island is 39km long and 45km wide, covering a total area of 2 512km. Réunion is considered an “overseas extension” of France and is therefore included in the European Union. This means the currency used on the island is the Euro. The principal towns are Saint-Denis, the administrative centre; Saint-Paul, the first “capital” and Saint-Pierre the most southerly town.
The water temperature varies from 23C degrees in winter to 30C degrees in summer. The locals are laid-back and welcoming. Getting to Réunion is easy with daily flights from Paris, which take about 11 hours.
There are more than150 species of coral and 500 species of fish to be found which makes for relaxed and enjoyable diving. The eastern and southern sides of the island are known as the wilder sides of the island.
Most of the dive operators are situated on the northwestern side of Reunion, where there are three main areas for launching boats. These dive centres are situated in the harbours, where boats are ready and waiting to take you out on the warm, quiet waters of the western side of the island.
La Réunion is an all-year destination. But if you want to see humpback whales, the austral winter (June to October) is the best time. Every year, they come to breed and give birth near our shores with the best action being from mid-August to mid-September.
Dive conditions are generally better during the summer months with the best visibility and warmest water. However, this is also the rainy season so the weather can “close in”.
Dolphins are to be found around the island throughout the year and visibility is very good for mostly 80% of the year.
Because diving Réunion is relatively unknown (and because of the distance to get there) La Réunion is a great dive destination if “frontier diving” is your bent. There’s nothing like diving places where few get to go.
Réunion offers a wide variety of dive sites. Just beyond the reef there are large flat reefs, beautiful steep walls and shipwrecks. Photographers tend to shoot wide-angle in the morning because conditions are calmer. In the afternoon, the shallower dive sites will delight you with their wealth of corals, sponges, reef fish and critters. This is a great opportunity to work on ambient light and macro underwater photography.
The greatest coral and marine life biodiversity is found on the west coast. There are also lava flows on the south side of the island, which are visited by some dive centers. These sites are exposed to strong currents, however, and for experienced divers only.
We also have some wreck diving at Réunion. The most famous is the Hai Siang at 55m deep (181ft). When the ship sunk it landed on its side, but then was righted by a cyclone. It’s a fun dive with a descent straight through the blue water column. Photographers can set up wide-angle or possibly ultra wide-angle (14mm).
Other popular deep wrecks include The Navarra at 50m (164ft), The Sea Venture at 45m (148ft) and Antonio Lorenzo at 38m (125ft). These are deep dives that require special training, however the photo potential is incredible. There are also some great wrecks in shallower water covered with abundant marine growth, fish and other exciting critters.
The macro diving is world-class at Réunion Island, with a wide range of biodiversity. The dive sites are usually found on the outer slopes of the barrier coral reefs, but you can also find some extraordinary encounters in the lagoons. Harlequin shrimp are often observed by free divers in the lagoons, so it’s certain that scuba divers can find them. There are also many colorful nudibranchs waiting to be found and photographed.
With great visibility and warm tropical waters, what more could a diver ask for?
With 40% of its approximately 2500 km2 territory classified as World Heritage Site by UNESCO, Reunion Island offers an amazing mix of authentic cultures and wild nature. As soon as you arrive on the island, you will feel and see the extraordinary variety of cultures that coexist in perfect harmony. From Asian cuisine to creole markets, from Buddhist traditions to Tamil, Islamic or Christian rituals, Reunion is a melting pot of cultures.
Réunion’s Most Popular Dive Sites
The Caves of Maharani: An original site in about 15m (49ft), which includes a series of cracks and caves adorned with skylights. On this dive, wide-angle is preferable in the morning when the position of the sun is best. Divers regularly see kingfish over one meter in length, making close passes while hunting. Lionfish are under the overhangs waiting for unsuspecting prey.
Passe de l’Ermitage: A cleaning station and meeting point for turtles and eagle rays. The turtles visit the cleaning station daily while also using the lagoon for shelter at night. The extensive seagrass beds provide an abundant food source.
Grand Tombant de la Point au Sel: This is one of the best dives at the island, but reserved for experienced divers since the current can be violent and unpredictable. There are great wide-angle opportunities with regular sightings of huge schools of jacks and pelagic fish (swordfish, marlin, tuna). Less frequently, divers will encounter a whale shark, hammerhead sharks or manta rays.
Cap la Houssaye: THE site for macro photography. On a regular dive you will see nudibranchs, mantis shrimp and ghost pipefish as well as turtles, barracuda and more. There is a huge meadow with sea slugs of all kinds, but beware of scorpion fish camouflaged on the bottom as they await passing prey. Visibility is average but this is not a problem for macro.
Réunion offers a wide variety of diving mixed with stunning topside landscapes. This small French island should be on every underwater photographer’s destination list!
