Diving in Grande Comore
Why dive here
Grande Comore offers some of Comoros's richest diving, with 364+ marine species recorded in the area - including barracuda, dugongs, dwarf minke whales, giant moray eels and humpback whales. Water sits around 30°C.
Grande Comore is an island that keeps you on your toes, a bit raw around the edges, and we love it for that. The diving here, especially around the volcanic walls, feels like exploring new territory. You're mostly looking at dramatic drop-offs and the occasional cave, all carved from ancient lava flows. We’re not going to lie, it’s not exactly teeming with dive centres, so if you're planning a trip, prepare for a bit of self-sufficiency. But for those willing to put in the effort, the rewards are there. We often find ourselves drifting past big schools of fusiliers, the light shimmering off their scales as they dart in and out of the shadows. Keep your eyes peeled for the resident Spotted Tobies, they’re always a cheerful sight, poking their heads out from the crevices. And here’s a tip: the currents can be quite frisky along the walls, so it’s not a place for a first-timer unless you're with someone who knows the local conditions intimately. Our favourite moments here are definitely during the late morning dives when the sun really lights up the reef, highlighting the greens and browns of the leaf and honeycomb corals. It’s rugged, a bit of an adventure, but genuinely rewarding.

Chindini
Chindini isn’t for the faint of heart, it’s a deep plunge into Grande Comore’s volcanic past, and our pick for experienced divers. You’re dropping onto a sheer wall, an obsidian curtain that stretches down into the abyss, well past recreational limits. We love how the light changes as you descend, the vibrant shallow blues fading to a deep, inky indigo. It’s here, in these shadowy depths, that the legend lives. While we can’t promise a coelacanth sighting – they’re notoriously shy – knowing you're in their ancient hunting grounds adds a real thrill. Even without a glimpse of the living fossil, there’s plenty to keep your eyes busy. Large meandroid brain corals anchor themselves to the rock face, massive and intricate. Keep an eye out for the subtle movements of Blackside Hawkfish perched on stony corals, or the flash of Blue-lined Tangs navigating the deeper sections. This isn't a site about colourful, shallow reefs; it's about the drama of the deep, the raw power of the ocean, and the possibility of seeing something truly extraordinary. Plan for a decent current, often pushing you along the wall, which just adds to the feeling of being a small part of something immense.
DEMOSTHENES
Demosthenes isn't your average wreck dive; it’s more of a history lesson you can swim through. This isn’t deep, just a couple of metres, which means the natural light really brings out the textures of the old steamship. You can easily spend an hour just finning around the superstructure, spotting where the mast once stood or tracing the lines of the deck. We love that you can see almost the entire 100-metre length of her, scattered across the shallows. What really makes it special for us is how the reef has taken over. Schools of yellowfin goatfish dart between twisted metal plates, and parrotfish graze on the algae growing across the hull. It’s an ideal spot for macro photographers, with nudibranchs and flatworms tucked into every crevice. We’d suggest going at high tide for the best visibility, but honestly, it’s a site that rewards repeat visits. Demosthenes is brilliant for snorkelers and divers who appreciate a slow, investigative dive, rather than a deep, fast drift.
Dragon's Teeth
Dragon's Teeth is a site that truly gets under your skin. Forget colourful corals for a moment, this is about the raw geology of Comoros, those jagged volcanic fingers plunging into the blue. We love how the light plays through the cracks, giving the whole place a slightly eerie, primordial feel. You'll spend most of your dive navigating a series of arches and swim-throughs, etched into the rock by ancient lava flows. Look up often; schools of Blackfish shimmer against the sunlit surface, and sometimes a lone Coral Hawkfish watches from a shadowy ledge. Our favourite part is a particular overhang at about 18 metres, where the honeycomb coral glows almost unnaturally green. Currents here can be lively, so it’s best suited for intermediate divers comfortable with drift, though often you're sheltered within the formations. We'd suggest going in the morning; the lower sun angle really enhances the drama of the rockscapes. It's a proper adventure for divers who appreciate the wilder side of the ocean.
Itsandra Reef
Itsandra Reef is one of those sites we always recommend for a relaxed afternoon dive, especially if you’re staying near Moroni. The reef itself slopes gently from about 5 meters down to a sandy bottom at 20, making it very comfortable for newer divers or for a long, slow exploration. We love the way the light filters through the shallows, illuminating patches of staghorn coral. Keep your eyes peeled for the smaller stuff here. While a green turtle might glide past, it’s the little characters that really stand out. We’ve spent ages watching the Arenatus wrasses darting about, or spotting the Banded Toby tucked away amongst the coral heads. If you’re patient, you might even catch a glimpse of a Bluestripe Pipefish weaving through the branches. The Blackstriped Cardinalfish often hang out in shady spots, a shimmering school, and the Epaulette Soldierfish are always a striking flash of red. It's not a dive for big pelagics, but for a calm, colourful introduction to Comoran reef life, it’s our favourite. The currents are usually negligible, so it’s easy to just drift and absorb the quiet hum of the reef.
KAMAL-EL-KUWAIT
The Kamal-El-Kuwait wreck is a real oddity, and that’s why we love it. This isn't some deep, dark behemoth. Instead, it’s a landing craft, sitting upright in a startlingly shallow 5 metres of water, almost beaching itself. We’re talking about an entire ship, practically at snorkel depth, and it means you get fantastic light play filtering through the superstructure. You can spend an entire hour just poking around the cargo hold and the wheelhouse, seeing how the light dances off the rusted metal. Our favourite thing about the Kamal-El-Kuwait is its accessibility and the way the marine life has completely taken over. Schools of snapper and small fusiliers swirl around the bow, and we’ve spotted plenty of moray eels peeking out from under the deck plates. It’s ideal for photographers looking for interesting compositions without the pressure of deep diving or strong currents. For anyone who usually feels rushed on deeper wreck dives, this one is a joy – you have all the time in the world to explore every nook and cranny. Keep an eye out for the small nudibranchs that often cling to the more exposed metalwork.
