Scuba diving in Seychelles offers an unparalleled marine adventure. This idyllic archipelago in the Indian hides a realm of underwater wonders waiting to be explored. The islands, adorned with granite and coral formations, offer dive sites that cater to both novices and seasoned divers. The experience is unparalleled – from the thrill of swimming alongside sharks and rays to the serene joy of floating amidst corals, Seychelles offers it all.
Sea Turtles: Gentle Giants of Seychelles Waters
The Green and Hawksbill Turtles are a sight to behold. Green turtles, with their smooth carapace, are primarily herbivores, while hawksbill turtles stand out with their pointed beak and beautifully patterned shell, predominantly feasting on sponges. Both species are regular nesters on Seychelles beaches, and spotting them is often a highlight of scuba diving in Seychelles. Bird Island, Aldabra Atoll, and Cousin Island are among their favored nesting sites, while divers hoping to meet them underwater often head to Silhouette Island and North Island.
Reef Sharks and Whale Sharks: Thrilling Encounters
The diverse species of reef sharks in Seychelles are fascinating and awe-inspiring. The Grey shark, with its torpedo-shaped body, is known for its agility in the water. The Silvertip, distinguishable by the white tips on its fins, is a bold species that sometimes approaches divers with curiosity. The Hammerhead’s unique “hammer”-shaped head broadens its sensory range.
And then there’s the Whale Shark—the ocean’s gentle giant and the largest fish in the sea, known for its majestic size and calm demeanor. For those keen to spot these creatures, the outer islands—especially around Aldabra Atoll and D’Arros Island—are prime areas for scuba diving in Seychelles experiences. Whale sharks may also appear between August and November around Mahé, Praslin, and La Digue.
Reef Fish, Coral Gardens, and Rays
The Seychelles waters are also home to an array of vivid fish species. The Lionfish, with its venomous spines and radiant stripes, captures immediate attention. The sleek and predatory Barracuda is another noteworthy mention, especially when they form schools. And the Giant Grouper, one of the most massive reef fish, isn’t shy and may even approach divers out of curiosity. These species can often be seen around St. Pierre Island, Anse Lazio, and the Fisherman’s Cove Reef off Mahé—making them classic sightings on many scuba diving routes.
Lastly, the majestic manta rays and stingrays are the graceful dancers of the Seychelles marine world. Manta rays, with their vast wingspans, move with incredible elegance and are sometimes seen somersaulting as they feed on plankton. Stingrays, with flatter bodies, prefer the ocean floor and can often be spotted camouflaged in the sand. For encounters, Aldabra Atoll and D’Arros Island are prime manta-ray spots, while sandy areas around Praslin and Mahé are ideal for stingrays during scuba diving in Seychelles trips.
Diving Hotspots
In the heart of the Indian Ocean, diving Seychelles presents a captivating underwater world waiting to be explored. One of the most fascinating spots is the Sunken Ship Dive. Here, divers can see the mysteries of intentionally sunken vessels, notably The Twin Barges and Aldebaran. These shipwrecks have become a hotspot for divers, though the depths, which plunge up to 40 meters, mean it’s a site more suited for advanced divers.
Another great spot is L’ilot, a granite islet that illuminates the night with its coral-covered landscape, offering spectacular nocturnal dives. Those who dive here are met with an ethereal glow of marine life, making every dive feel like a dream.

For divers who appreciate variety, Baie Ternay Marine Park is a must-visit location. This protected area is renowned for its distinctive underwater topography and the rich diversity of marine life that inhabits it. From swaying corals to schools of darting fish, it represents a true microcosm of the ocean’s wonders and is a favorite stop for those exploring scuba diving in Seychelles sites with varied terrain.
Shark enthusiasts, meanwhile, often gravitate toward Brissare Rocks. Recognized as a major hotspot, it promises close encounters with several shark species, delivering an adrenaline-filled dive experience. In contrast, Chuckles Rocks offers a more relaxed atmosphere. Here, divers can enjoy vibrant coral formations and abundant marine life in calm conditions, making it an excellent option for photographers and those seeking a tranquil scuba diving experience.
For novices taking their first plunge, St Pierre Island is an ideal choice. The site offers gentle conditions and excellent visibility, along with opportunities to see turtles and reef sharks up close. White Bank is another beginner-friendly site, known for its warm waters and clear conditions that allow even first-time divers to fully enjoy scuba diving in Seychelles without difficulty.
For seasoned divers seeking a challenge, South Marianne Island delivers an unparalleled adventure with its dramatic underwater landscapes and stronger currents, making it best suited for advanced skill levels. Lastly, Aldabra Atoll, a UNESCO World Heritage Site, offers a once-in-a-lifetime dive among endemic species found nowhere else on Earth. As a protected area, special permits are required, but for experienced divers, it represents the pinnacle of scuba diving in Seychelles.

Choosing the Perfect Time:
The Seychelles waters are consistently inviting due to their equatorial climate, ensuring that at any time of the year, divers are able to enjoy themselves. That said, each season introduces its distinct diving experience.
From June to August, the south-east monsoon cools the water down to around 25°C. This drop in temperature, combined with the presence of plankton which might slightly compromise visibility, has an exciting advantage—it attracts the majestic whale sharks. This period offers divers the opportunity to see this sight that’s rare outside of these months.
On the other hand, from November to May, diving conditions reach their zenith. Divers can enjoy the unparalleled clarity with visibility stretching up to 30 meters, bask in the warmth of the waters, and relax in the calm seas. It’s arguably the ideal time for anyone looking to explore the underwater wonders of Seychelles.
However, a little heads up for those planning their trips between December and February: although the diving conditions remain excellent, occasional heavy rainfall might make an appearance, adding a different rhythm to the diving experience.
Choose your preferred season and dive into the unparalleled beauty that scuba diving in Seychelles has to offer.
