Imagine sliding beneath turquoise, tropical waves to discover yourself surrounded by schools of spinning colored fish, curious sea turtles, and coral-colored gardens that seem like otherworldly vistas. Seychelles is having its most dazzling year of diving and snorkeling in 2025 — and if you're even remotely drawn to the sea, it's your year to do it.
The once-troubled Seychelles' coral reefs are back in recovery with outstanding color and vitality. Thanks to decades of revitalization work, the once-wash-out and lifeless reefs are teeming with life.
Picture this: massive coral skyscrapers, soaring clownfish, and the shining rush of reef fish by the hundreds. Swim in seas where Acropora corals smother themselves in iridescent purples and blues, and sea creatures undulate through coral fortresses transformed into submerged metropolises.
Recovery has been expedited through conservation efforts with coral nurseries and micro-fragmentation.
Off Mahé and Praslin, corals once sentenced to oblivion are now becoming stronger and faster than ever.
Divers enjoy visibility of up to 30 meters, showing off otherworldly underwater landscapes and furious marine life.
An Explosion of Marine Life: It's a Living Aquarium Out There
If you're wondering why 2025 stands out, it's the phenomenal number and diversity of creatures that line Seychelles' shores today.
Turtles are in full swing again. See hawksbill and green turtles gliding gracefully across the reef, or even witness them laying their eggs on deserted beaches.
Sharks at the reef, blacktips and whitetips, are more in sight and relaxed around divers than before.
Snorkelers are often eye to eye with eagle rays, reef octopus, or even schooling flying fish as they break through the surface.
Even one-time visitors are making appearances. Manta rays are returning in larger numbers, and different dive groups have logged mind-boggling sightings of shy whale sharks — the sea giants.
Where to Snorkel and Dive in 2025: Places You Won't Want to Miss
Shark Bank – For Adventure Seekers
Off Mahé, eight kilometers outside, is Shark Bank, which is alive with activity. Here's a haven for great schools of trevallies, snapper, and rays and the occasional couple of hammerheads. Currents provide a smorgasbord for sea life, and you'll be diving straight into the feast.
Aldabra Atoll – Seychelles' Wild Frontier
Distant, untouched, and filled with life — Aldabra is the diver's holy grail. One of the world's largest atolls, its coral canyons and underwater walls are laden with sharks, groupers, turtles, and shimmering reef fish. Snorkelers can stay close to the coast and still glimpse giant clams, colorful coral, and octopuses.
Baie Ternay Marine National Park – Easy Access, Rich Rewards
Just a boat trip from Mahé, Baie Ternay is a snorkeler's paradise. With calm, crystal-clear water, it's ideal for families, beginners, and photographers. Keep an eye out for turtles feeding in seagrass beds, stingrays gliding quietly by, and schools of batfish slowly exploring your mask.
Sainte Anne Marine National Park – The Snorkeler's Dream
A shallow water heaven with reefs looming barely beneath the surface. Take a glass-bottom boat tour or snorkel directly from the beach. Damselfish, wrasses, and parrotfish flit about between your legs as you glide through radiant crystal-clear lagoons.
Eco-Tourism Done Right: Dive With Purpose
The real beauty of the 2025 season isn't the marine life — it's the consciousness that comes with it. Seychelles is showing the world how to play in nature without despoiling it.
The number of tourists visiting sensitive reef environments per day is now controlled by tour operators.
There's a complete ban on single-use plastics, even on vessels.
Dive briefings are now followed by marine biology trivia and conservation tips so each dive adventure is also an educational experience.
Want to dive with a cause? Join a "plant-a-coral" dive, or ride with local scientists for a half-day of tagging turtles and reef fish monitoring. You'll leave the islands knowing you saw them, but you helped secure their future as well.
Be part of the Research: Citizen Science in Action
In 2025, Seychelles is providing visitors with a unique opportunity to participate in marine science. Various programs welcome visitors to participate in actual conservation projects:
Contribute your underwater photos to help scientists monitor coral health.
Embark on a shark-tracking expedition with GPS gear and tagging gear.
Participate in turtle walks during nesting season and help protect hatchlings.
These escapades are not just hip stories — they're ways to develop deeper connections with the sea and the creatures that live within it.
