Diving in Sumatra
Why dive here
Sumatra is a diving destination where divers can encounter mantis shrimp. Water ranges 29-32°C, warmest April, May, June.
Sumatra, often overshadowed by Indonesia’s more famous dive destinations, offers a compelling mix for those willing to venture a little further. Off the northern tip, Pulau Weh serves up some genuinely nice reef diving in the Andaman Sea. We’ve had some memorable drifts there, spotting large schools of Ehrenberg’s snapper and plenty of orbicular batfish hanging around the pinnacles. The corals, like the cactus coral, are in good shape, and we often find ourselves drifting past big patches of them. Move further south and west to the remote Mentawai Islands, and it’s a different vibe entirely. Here, you’re often diving completely uncrowded reefs, a real treat when you consider some of the busier spots in Southeast Asia. The currents can be quite lively in places, making for some exhilarating dives, and while the surf breaks draw a crowd, the underwater world feels largely untouched. You’ll see plenty of checkered seaperch and redcoats darting amongst the reef structure here.

Adjis Reef
Adjis Reef offers a straightforward dive on a coral reef in Sumatra. You’ll find a good mix of hard and soft corals, with the usual reef fish flitting about. It's a solid choice for those looking for a relaxed dive rather than something high-octane. We think it’s best suited for divers who appreciate a calm exploration of a healthy reef.

Agus dream
Agus Dream in Sumatra delivers a good drift dive along a sloping reef. Expect a steady parade of reef fish and, if you're lucky, a turtle or two cruising past. The site is a solid choice for divers who enjoy covering ground with the current and want a relaxed tour of a healthy reef. It's not a site for macro enthusiasts, but it provides a pleasant wide-angle view.
Arus Balee
Arus Balee gives you a good cross-section of what Sumatra offers without overwhelming you. It's a reliable spot for macro enthusiasts, with plenty of those little yellow-red pygmygobies darting around and the occasional spotted toby or orange-spotted blenny tucked away. We often find brownbanded wrasse picking through the staghorn coral, and if you’re patient, a dwarf moray might peek out. It’s a comfortable dive, nothing too strenuous, ideal for getting back into things after a travel day or for those who prefer a more relaxed pace. You won't find huge pelagics here, but the sheer number of smaller reef fish, like scissortail sergeants and Pacific gregory, always keeps things interesting.

Beting Eka
Beting Eka, off Sumatra, offers a solid reef dive. We usually find a good mix of hard and soft corals here, providing shelter for various reef fish. Currents can pick up, so it's a site better suited for divers comfortable in drift conditions who enjoy a relaxed pace watching the reef go by.
Coral Reef
Coral Reef on Sumatra’s north side, near tiny Koh Ha, is a proper easy-going dive. We usually drop in deep, around 30 metres, and then let the reef slowly bring us up towards the shallows. It’s ideal for a relaxed dive, especially if you’re getting back into the swing of things, or even if you’re just keen on a long, slow bottom time. Down in the sand, we almost always find a few Kuhl’s stingrays, masters of disguise, with only their eyes giving them away. As you get shallower, the reef comes alive. Keep an eye out for the Flashlight Fish in the small crevices; they’re pretty shy but worth the wait. We’ve also had some fun spotting Big-spot Anglers here, perfectly camouflaged against the corals. Look closely for the smaller stuff too, like the Goldmann's Sandgoby darting around its burrow or the vibrant Blue-ribbon Wrasse. It’s a site that rewards a slow pace and a keen eye. Our favourite time to dive here is late morning, just as the sun starts to properly illuminate the shallower coral gardens.
Cubadak Pier
Cubadak Pier offers a straightforward dive, often a good option for a second tank. You'll find a healthy variety of critters tucked into the pilings – nudibranchs, lionfish, and small schooling fish are regulars here. It’s a solid spot for macro enthusiasts and photographers looking for easy conditions and decent bottom time. Expect gentle currents, making it suitable for newer divers too.
ELOUT
Elout, off the coast of Sumatra, offers a poignant dive into history. This steamship, bombed and sunk by Japanese aircraft in January 1942, now rests at a shallow 11 meters, making it accessible for most open water divers. The wreck itself, classified as dangerous in some reports due to its age and wartime demise, is a skeletal structure. We found it’s become home to a fascinating array of critters, from schools of snapper darting through the rusted hull to curious nudibranchs clinging to the encrusted metal. It’s a somber, evocative dive, but one that rewards careful exploration and an appreciation for the past.
Fananas
Fananas offers a good drift dive along a sloping coral reef. Keep the reef to your left as you head southeast, letting the current carry you past plate corals and small bommies. We've often spotted white-tip reef sharks cruising the deeper edges here. It’s a straightforward dive, well-suited for divers who enjoy a relaxed drift.
FOKUS
Fokus is a decent wreck dive, tucked away from the more famous Sumatran spots. We’re talking about a motor vessel, lying upright at 24 metres, which makes for a straightforward penetration if you’re comfortable with overhead environments. It’s listed as a "dangerous wreck" which, for us, just means a bit of extra caution and perhaps a solid dive torch to cut through the shadows inside. You’ll find resident schooling fish, maybe a curious snapper or two peeking from portholes, and the usual suspects of coral growth colonising the hull. It’s a good stop for wreck enthusiasts who appreciate a quieter site without the crowds, offering a solid hour of exploration.
Gosong Barak
Gosong Barak offers a look at a healthy coral reef ecosystem off Sumatra. We've seen a good variety of reef fish here, from parrotfish to schooling fusiliers, all busy around the hard corals. It's a straightforward dive, generally calm, making it a good option for divers looking for a relaxed exploration rather than a high-adrenalin drift.
