StandoutExceptional marine biodiversity

Look, Singapore diving isn't the Maldives. Let's get that out of the way. But the Southern Islands, just a short boat ride from the city, offer a surprising amount for a quick fix. We’re talking about those fringing reefs and a few decent wrecks, often with stronger currents, which means more action. Drop into Pulau Hantu and keep your eyes peeled for common seahorses swaying gently in the current, or maybe a bearded flathead goby hunkered down on the sand. The vis can be temperamental, shifting from a murky five metres to a respectable ten or twelve metres on a good day, but that just adds to the hunt. We’ve had some fantastic encounters with spotted sea catfish cruising in formation, and the blue and yellow groupers are always a welcome sight against the soft corals. Our favourite insider tip? Dive here on an incoming tide. You’ll get better vis and usually, a more vibrant reef. The currents can pick up, so be ready for a bit of a workout, but that’s often when you spot the larger schools of Indian scad zipping past. It’s not pristine, but it’s real, and it’s right on Singapore’s doorstep.

AB9

The AB9 wreck in Singapore's Southern Islands is a tanker vessel lying at 27 metres. It's a proper wreck dive, with plenty of metal to explore, though penetration is not advised due to its dangerous classification. We've seen various reef fish and some decent sized snapper making a home in its structure. It’s a good spot for divers keen on wrecks rather than coral, and comfortable with deeper dives in sometimes limited visibility.

27m

ABU MOOSA

Abu Moosa is one of those Singapore wrecks that still feels like a proper mystery, even after all these years. This tug went down in 1989, and while it's officially classified as "dangerous" (which often just means it’s a bit of a scramble), we find it’s more exciting than alarming. You'll hit the deck around 25 metres. Visibility here can be a bit of a lottery; sometimes you get 8 metres, other times it’s more like 2, but that just adds to the adventure, right? What we love about Abu Moosa is the sheer scale of the thing. It’s upright and largely intact, providing plenty of nooks and crannies to poke your head into, assuming your buoyancy is dialled in. We’ve spent dives tracing the lines of the superstructure, imagining it as it was. Look out for the resident batfish; they're usually schooling off the bow. On a good day, with a bit of ambient light, the way the schools of snapper weave through the holds is quite something. It’s a dive for those who enjoy exploration and don't mind a bit of a challenge in lower vis. Go during slack tide for the best chance of a relaxed penetration.

25m

AH LAM II

Ah Lam II is one of our favourites in the Southern Islands, definitely a standout. It's a tugboat that went down back in '92, and the story of its sinking – squeezed between a bulk carrier and its own tow – gives it a real character. Dropping to 27 metres, you'll find the wreck largely intact, sitting upright on the seabed. We love exploring the engine room, often finding large groupers lurking in the shadows. The wheelhouse is usually teeming with schooling fusiliers, so thick they almost block out the ambient light, and we've regularly seen barracuda circling the mast. It's a surprisingly fishy wreck, probably because it's one of the more substantial structures down there. For photographers, the way the light filters through the superstructure can be beautiful on a sunny day, especially around mid-morning. We'd suggest checking the tides; a slack tide makes for a much more relaxed exploration, though a gentle current often brings in more pelagics. Visibility here can be hit or miss, typical for Singapore, but when it's good, Ah Lam II really shines. It's an excellent dive for those who enjoy wreck penetration or just want to spend time observing the resident marine life.

27m

ANGSA 3

Angsa 3 isn't just a wreck; it's a slice of history, well, a dangerous slice. We love how this site feels like an archaeological dig rather than just another dive. Maxing out at 10m, it's a shallow dive, but don't let that fool you into thinking it's easy. We've seen some pretty strong currents here, so pick your day carefully, ideally on a slack tide. The wreck itself is quite broken up, but that’s part of its charm. You’re not exploring a pristine ship, more a field of intriguing debris. Look for the large, corroded boiler – that's often our favourite spot. Schools of yellowtail scad dart through the metalwork, and we often spot cuttlefish camouflaged against the rust. It’s a site that rewards patience, allowing you to really pick through the pieces and imagine the ship's past. This is a site for divers who appreciate history, enjoy a bit of a challenge, and love the hunt for macro life amongst the ruins.

10m

AOI MARU

The *Aoi Maru* isn’t the deepest wreck we dive in Singapore, topping out at a respectable 22 metres. But what it lacks in sheer depth, it makes up for in character. Sunk in 1975, this old motor vessel now lies on its side, a dark, hulking shape against the silty bottom. We love the way the light filters down, creating these dramatic shafts through the particles, especially on a sunny morning. You can still make out the superstructure, and there are plenty of entry points if you’re comfortable with overhead environments and have the right training. As you get closer, the wreck hums with activity. Look for lionfish tucked into shadowy crevices, their spines fanned out like feathered capes. We’ve spotted bamboo sharks resting in the sand nearby, almost perfectly camouflaged. Our favourite moments here are spent hovering over the deck, watching schools of fusiliers dart and swirl, occasionally parting to reveal a lone batfish inspecting you. It’s a proper historical dive, feeling a little like you’re exploring a forgotten time capsule rather than just a dive site. Best to hit this one on an incoming tide, before the current picks up too much. It’s ideal for wreck enthusiasts who appreciate the history as much as the marine life it now supports.

22m

ARROW

The Arrow, a roll-on/roll-off vessel sunk back in ‘79 after hitting something submerged, sits at 25 metres in Singapore’s Southern Islands. It’s definitely a wreck dive, and while it might not have the dramatic structure of some others in the region, it’s got a personality all its own. We’ve found the wreck provides a decent home for various schooling fish, and you often see barracudas patrolling the perimeter. Visibility can be a bit hit or miss, so it’s one to jump on when conditions look good, usually early mornings. It’s a solid dive for those who enjoy exploring the bones of a ship rather than just a reef.

25m

ARWANA

The Arwana, a carrier vessel, settled upright on the seafloor after an unfortunate encounter. She's a dangerous wreck, no doubt, but that's part of her charm – she’s not been picked clean or artificially stabilised. We love the eerie silhouette she casts against the sometimes murky Singaporean waters, a genuine challenge for navigation, even at just 21 metres. Diving Arwana feels like stepping into a forgotten corner of history. Penetration isn't really an option, but we still spend ages exploring the superstructure. Look closely at the hull and you’ll spot a surprising amount of soft coral growth, surprisingly vibrant given the low light. Our favourite game is spotting the resident batfish schools, often circling the mast in a slow, hypnotic dance. They’re usually joined by snappers and fusiliers, darting in and out of the darker sections. It’s a dive for those who appreciate the quiet mystery of a wreck, the kind of place that reveals more with each visit. Come prepared for limited visibility and you’ll be richly rewarded.

21m

ASSIMI III

Assimi III, for us, is hands down the best wreck dive in Singapore. It’s a proper ship, not just a collection of scattered metal, and its history adds a layer of intrigue. We love dropping down onto the massive tanker, its sheer scale impressive even after all these years underwater. You can really feel the cold thermocline at 20-25 meters on the descent, a stark contrast to the warmer surface, before the wreck gradually emerges from the gloom. The fire in the engine room back in '68 left a dramatic mark, and exploring that area is our favourite part. It’s completely stripped, open to the elements, and light filters through in eerie shafts. We’ve found huge schools of fusiliers here, so thick they almost block out the light, darting around the superstructure. Look out for the resident batfish and emperor snappers, often lurking in the deeper, darker sections. Be mindful of the currents; they can pick up quickly, especially around the bow and stern, so good buoyancy control is key. This is a dive for experienced wreck enthusiasts who appreciate a bit of mystery and a tangible piece of maritime history.

33m

BANTEN

The Banten wreck, down at 37 meters, is one of our favourites in the Southern Islands if you’re looking for a serious penetration dive. This motor vessel went down in 1980, and time’s really worked its magic on the structure. We love how the hull plates have buckled and torn, opening up all sorts of swim-throughs and gaps that weren’t there when she first sank. You’ll spend most of your bottom time exploring the engine room and cargo holds, where visibility can drop quickly if someone kicks up silt, so good buoyancy is key. Giant groupers and batfish school off the bow, and we often spot nurse sharks tucked away in the darker corners of the wreck. Keep an eye out for nudibranchs on the deck plating, too. This isn’t a site for beginners; we’d suggest divers have solid experience with deep dives and wreck penetration, and definitely bring a good torch. The currents here can be unpredictable, sometimes ripping, sometimes slack, so it’s always a bit of a gamble, but the reward is a genuinely atmospheric dive.

37m

BETHLEHEM

Bethlehem is one of those Singapore wrecks that always gets us talking. It's not the easiest dive, sinking to 30m, but the rewards are there if you're comfortable with deeper profiles and potentially tricky conditions. This 125m cargo vessel, built in 1939 and tragically broken in three as it sank in 1969, feels properly substantial down there. We love how the sheer scale of the ship means there's always a new section to explore, even after multiple dives. Dropping down, the bow section is usually our first stop. You can still make out the anchor chains and some of the superstructure, now completely draped in soft corals and sponges. Schools of fusiliers often swirl around the mast, and we’ve even spotted marble rays resting on the sand nearby. The mid-section, where the break occurred, is a chaotic jumble of plates and beams, creating fantastic swim-throughs if you're cautious and well-trained. Look closely here for nudibranchs and flatworms, camouflaged against the encrusting life. The stern is often quieter, offering chances to peek into cargo holds where batfish hang in the gloom. It’s a dive for those who appreciate history and the slow, powerful reclamation of steel by the ocean.

30m

BINTANG MAS

The Bintang Mas is, without a doubt, our favourite wreck in Singapore. Dropping down onto her, you immediately feel the history. This isn't just a pile of metal; she was a motor vessel, 32 metres long, and lies at a decent 35 metres. We love how intact she feels despite being classified as "dangerous," a nod to her age and the currents that sometimes sweep through here. What really makes the Bintang Mas special is the way marine life has completely taken over. We've seen schools of fusiliers so thick they block out the sun, and the resident batfish here are always curious, swimming right up to your mask. Look closely into the nooks and crannies of the superstructure and you’ll often spot massive groupers lurking, or even a bamboo shark tucked away. We’d suggest going during slack tide, usually around the moon’s quarters, for the best exploration. It lets you really take your time and appreciate the scale of her, from the bow right back to the stern, and peer into the hatches without fighting the flow. This site is definitely for those who appreciate a wreck with character, and a bit of a challenge when the current picks up.

35m

BLACKMARK

Blackmark is one of our favourites in the Southern Islands, not because it’s a giant wreck, but because of its character. This old ferro-concrete workboat, sunk back in ‘80, rests upright in about 11 metres of water. It’s pretty compact, maybe 15 metres end-to-end, but what it lacks in size it makes up for in how it’s aged. We always find something new here. The concrete hull has become a canvas for soft corals, particularly a striking orange cup coral that blooms in the darker sections. On a sunny day, with decent visibility, you can really appreciate the colour. Inside the open hold, we often spot robust ghost pipefish swaying with the surge, nearly invisible against the encrusted walls. Look closely for nudibranchs, especially on the propeller shaft. It’s a gentle dive, perfect for photographers or anyone wanting to spend time exploring the nooks and crannies of a unique artificial reef. Just keep an eye on the tide; the currents here can pick up, making it a bit more of a workout than you might expect for such a shallow spot. We usually aim for slack high tide for the clearest water and easiest conditions.
