Why dive here
Prony Bay offers some of New Caledonia's richest diving, with 73+ marine species recorded in the area - including dugongs, great white sharks, humpback whales and sperm whales. Water ranges 22-27°C, warmest January, February, March.
Prony Bay. We love it. It's got this truly unique vibe, a bit eerie, a bit wild, definitely not your average Pacific postcard. Our favourite? Without a doubt, the hydrothermal chimneys. Imagine diving alongside plumes of warm, mineral-rich water rising from the seabed, creating this ethereal, shimmering effect. You feel the temperature shifts as you pass them, a strange warmth against your cheek. And then there's the Needle of Prony, a massive pillar that just shoots up from the depths. Diving around it, you’re often surrounded by schools of fusiliers, sometimes so thick they practically blot out the sun. The killer alga is a local curiosity, a strange green carpet in places, and you'll spot plenty of Redfin Butterflyfish darting in and out of the crevices. Keep an eye out for the Lemon Peel and those vivid Schlegel's Parrotfish munching away. Currents can be a factor here, especially around the Needle, so good buoyancy is key. We’d suggest going in the drier months, May to November, for the best visibility, but even in the "wetter" season, the unique geology makes it worthwhile. It's not about pristine corals here; it’s about the raw, volcanic energy of the place.

Aiguille de Prony
Dropping onto the Aiguille de Prony, you’re looking at a distinctive pinnacle formation in Prony Bay. It's a solid, interesting structure that draws in a good variety of reef fish. The site is generally straightforward, making it a good pick for those comfortable with deeper dives but not seeking a strong current challenge. Expect a pleasant, unhurried exploration.
Aiguille du Prony
Right, the Aiguille du Prony. It’s not your typical deep dive, not even close. This is a genuinely unique spot, a true standout in Prony Bay. You’re essentially diving the very top of a towering needle of rock that surfaces in the middle of the bay, hence “Aiguille.” The depth listed, 1 meter, that’s its peak. We’re talking a snorkel or a very shallow free dive, maybe even just peering over the side of the boat on a calm day. What makes it special, though, is what happens right there, just below the surface. This little pinnacle acts like a magnet for pelagics, sometimes bringing them into impossibly shallow water. We’ve seen dugongs here, incredibly, just grazing on the seagrass nearby, and even oceanic manta rays gliding through, their wingtips almost breaking the surface. It feels surreal to watch a manta in water so shallow you can practically stand up. The coral growth is impressive for such an exposed spot; we're particularly fond of the dense patches of staghorn coral, creating little mazes for smaller fish. Look closely, and you might spot a Martin's cowrie tucked away. It’s a site that rewards patience and a keen eye, best enjoyed when the bay is glassy calm, usually early mornings before the breeze picks up. This isn't a site for ticking off species, it’s for experiencing something truly different.
Boulari Plateau Manta
Boulari Plateau Manta in Prony Bay is exactly what it sounds like, a manta ray magnet. We're talking proper reef mantas, not just a passing glimpse. This plateau, sitting at a comfortable 13 metres, acts as a cleaning station, so you settle in and watch the show. We’ve had dives here where we barely moved, just observing these gentle giants glide in, hover over the coral heads, and get serviced by the smaller fish. The current can be stiff, sometimes really ripping, so it’s a drift dive for sure. You’ll be swept along the edge of the plateau, eyes peeled, then you hit the sweet spot. When the mantas are here, they're the main event. But don’t forget to look around. Schools of blue and gold fusiliers are everywhere, and we’ve seen some hefty grey reef sharks patrolling the deeper edges. Keep an eye out for orbicular batfish too, they often hang around the reef crest. Our pick for timing is definitely early morning, before any boat traffic picks up. The water generally holds 19 metres of visibility, a clear, warm blue that just feels like New Caledonia. This site is for divers who appreciate a reliable big animal encounter and don't mind a bit of a current. It's a drift that delivers.
Boulari Plateau Manta
Ed's Wall in Iron Bottom Sound is a cracking little spot. We love how it just drops straight down, like someone took a knife to the seabed. It’s not the deepest wall dive around, topping out at 25m for us recreational folk, but that just means more time to poke around. And you really do want to take your time here. The wall itself is just riddled with nooks and crannies, perfect hiding spots for things like Gardiner's Headshield Slugs or a grumpy Stonefish. Our pick for finding the most interesting stuff is to hug the wall closely, keep your eyes peeled for movement in the shadows. Entry is usually over a sloping reef, a proper meadow of staghorn corals. It’s a bright, buzzing place, full of Blue and Gold Fusiliers darting about and a good handful of Spotted Surgeonfish grazing. We’ve had dives where the shallow reef felt almost as lively as the wall itself. Visibility often sits around 30m, which is a real treat when you’re looking down that vertical drop. This site suits divers who appreciate the small stuff, who don't mind slowing down and hunting for critters rather than just cruising past big pelagics.
Corne de Tenia
Corne de Tenia in Prony Bay offers a gentle introduction to New Caledonia's coastal diving. It’s a shallower site, perfect for newer divers or those looking for a relaxed multi-level profile. You'll find schools of fusiliers here, often sheltering amongst the soft corals, with the occasional reef shark gliding past in the blue. We'd suggest it for an easy afternoon dive, particularly if the wind is up elsewhere.
Epave du Snark
Prony Bay’s Epave du Snark isn't one of those massive warships, but it's got a quiet charm. This small wreck, possibly a fishing boat or a yacht, sits upright on the sandy bottom, pretty much intact. We found schools of bannerfish fluttering around the mast, and inside the holds, it’s common to spot cardinalfish sheltering in the gloom. It’s a comfortable dive, usually with mild current, making it a good option for those newer to wreck diving or anyone looking for a relaxed exploration rather than a technical challenge. Keep an eye out for nudibranchs making their way across the hull.
épave du snark
Kansas Reef is one of those sites that just feels alive. We've always been drawn to how the sea plumes here sway, catching the current, reminding us of fields of wheat – a nod to its name. Dropping in, you're immediately struck by the sheer volume of French grunts and glassy sweepers schooling, often so thick they dim the light. Keep an eye out for the mottled jawfish, they’re usually bobbing near their burrows, and we’ve often spotted orangespotted filefish picking their way through the corals. This isn’t a deep site, maxing out around 23 meters, but the currents can be lively, so it’s best for divers comfortable with a bit of drift. Our top tip? Go in the late morning, the light filters through the swaying corals beautifully then, and we've found that's when the barracuda are most active, often cruising just above the reef. You’ll definitely see black durgon and creole wrasse feeding in the current, and if you’re lucky, an eagle ray might glide past in the deeper sections. It's a proper reef dive, full of movement and life, perfect for those who enjoy a dynamic environment rather than just static observation.
épave du Umbolt
Kapalua Beach is one of those spots we always point people towards when they’re looking for a relaxed dive in Maui. It’s shallow, topping out around 9m, which makes it perfect for longer dives or for easing back into things after a travel day. We love slipping in here mid-morning, after the early beachgoers have settled in but before the afternoon rush. What makes Kapalua really click for us is the reef just off the beach. It’s a busy little neighbourhood, often with dozens of Green Turtles just munching away on the algae, completely unbothered. You’ll weave through coral heads and rocky formations, keeping an eye out for Leopard Blennies peeking from crevices or a Giant Moray peering out. Visibility often hits 15m, sometimes more, especially on a calm day, giving you plenty of light to appreciate the vibrant corals and the schools of Bluelined Surgeonfish zipping past. It’s a genuinely peaceful dive, best suited for those who appreciate the smaller details and the company of turtles.
Ever Propérity
Katak Drop sits just off Gili Petagan, a quick 20-minute boat ride from mainland Lombok. We’ve found the slope here to be gentle, winding down to around 23 meters, which makes for a pretty relaxed dive. Visibility usually hovers around 15 meters, enough to take in the healthy corals and the usual suspects like Brown-lined Puffers and Spotted Hawkfish. It’s a good choice if you're looking for an unhurried dive with decent coral cover, perhaps a nice warm-up or wind-down to a day out.
EVER PROSPERITY
The Ever Prosperity, resting in Prony Bay, offers a truly unique dive. We don't often get to explore wrecks that were once such impressive vessels, built in '52 and stretching over 137 metres. It went down in 1970, running aground on Abore Reef, and now sits as a fragmented but fascinating structure. What we love about this wreck is how the bay’s calm, almost lake-like conditions have preserved it, at least in parts, while also allowing nature to reclaim it. We’ve finned through schools of fusiliers so thick they momentarily blocked out the light filtering down from above, a truly immersive sensation. Look out for the resident moray eels peeking from crevices; they’re often quite bold here. The sheer scale of the ship is what really grabs you – imagining it sailing from Sydney to Noumea puts its current state into perspective. We’d suggest focusing on the bow and stern sections; they tend to be the most intact and offer the best nooks for spotting smaller critters. While it's fragmented, the accessible areas make it an ideal wreck dive for those comfortable navigating larger structures and who appreciate the blend of history and marine life.
EVER PROSPERITY
The Ever Prosperity isn’t just a wreck; it’s a colossal, open invitation to explore. This old steamship, grounded in 1965, spans an impressive 134 metres, and our favourite part is how much of it remains accessible, even at shallow depths. We’ve spent hours weaving through the superstructure, where the sheer size of the boilers and engine room really hits you, especially with shafts of sunlight cutting through the gloom. Visibility here is often very good, letting you appreciate the scale from afar before you get up close to the detail. We love the resident batfish schools that swarm around the bow, and the smaller critters, nudibranchs and flatworms, tucked into the holds. It’s a fantastic site for photographers, with so many compositional possibilities, and because much of it sits in relatively shallow water, you get ample bottom time to really soak it all in. Just keep an eye on your buoyancy; it’s a big wreck with plenty to bump into.
Extasy
Kat's Kables always feels like a bit of a treasure hunt, and that's why we love it. The real draw here isn't just the resident parrotfish or the occasional sleepy whitetip reef shark tucked under a ledge, it’s the sense of history. You're swimming over these old communication cables, relics from when Direction Island was the internet hub of the Indian Ocean. It’s a strange juxtaposition, seeing the vibrant corals growing right alongside this chunky, industrial-looking cable disappearing into the blue. We usually drop in and follow the cable, keeping an eye out for mantas cruising by in the deeper water. The coral growth here, particularly the Cauliflower and Montipora, is really something. Look closely among the coral bommies for the smaller stuff, like the adorable Reef Margin Blenny or a well-camouflaged Coral Hawkfish. Visibility often pushes past 25 metres, giving everything a lovely, clear definition. This site is perfect for those who appreciate a bit of unique history with their reef dive, offering a gentle drift over a healthy reef with an interesting twist.
