10 Dive Sites You Must See in the Solomon Islands

Wide-angle, macro, wrecks and the most beautiful diving in the Solomons
By Joanna O'Shea

Solomon Islands is a hidden gem in the South Pacific. Still relatively new to tourism, it sees far fewer visitors each year that its neighbours Fiji and Vanuatu. This means pristine reefs, and no other boats crowding the dive sites. One of the reasons Solomons is know for the best diving in the world is because it has such a variety of diving options: reefs, wrecks, big animals, little critters, caves and beaches. Here are my top ten favourite sites.


Twin Tunnels

Twin Tunnels is named for two big vertical lava tubes in the sea mount. The tubes are next to each other; you can pick either and swim down to where they join and open up on the side of a reef wall at about 36m. The walls of the lava tubes are covered in fans and whip corals, and occasionally you find nurse sharks resting on the sand at the bottom. This dive is great not only for the lava tubes, but for the huge schools of fusiliers that constantly school around the entrance to the tunnels, and the fabulous reef on top. You can find pygmy seahorses in the fan corals, hairy squat lobsters live in the edges of the barrel corals, and it’s a great place to find cuttlefish, octopus, and eels.

This shot was taken from about halfway down the lava tube, looking straight up towards my dive buddy as she descended.

White Beach

This site is surprisingly not a white beach; the island is actually edged by mangroves. It was an American military base during the WWII, with the code name “White Beach”. When the troops departed, they pushed everything into the sea. So if you’re into wrecks, there is plenty here to explore: trucks, pieces of machinery, bullets and old coke bottles. But I love this site for its incredible macro life. Nudis galore, jawfish, pipefish, harlequin shrimp, mandarin fish and tons of juvenile fish. Along the edge of the mangroves, you can see pyjama cardinals and archer fish loitering amongst the tree roots.

Pipefish are abundant at this site, and they are always happy to pose.

Archer fish are known for their ability to shoot down resting insects by spitting a jet of water to knock down prey from tree branches above the water. They are the sharpshooters of the ocean, able to account for the refraction of the light on the water surface to hit their target.

Leru Cut

Probably the most famous dive site in Solomon Islands, Leru Cut is an indent into the side of a small island which runs for about a hundred meters, around 12m deep. You can surface at the end of the “cut”, and feel bizarre being in scuba gear in the interior of the island, while looking up at huge trees with vines hanging down and birds calling.

Mary Island

Mary Island, also known as Mborokua, is the best site for schooling jacks, barracuda and sharks. Huge bumphead parrotfish are also common.  As if that wasn’t exciting enough, there is an underwater volcano nearby, which gives off the occasional rumble.

Battery Point

This is my favourite site for night dives. The sandy slopes are a great place to find little critters including mantis shrimps, bobbit worms, snails and nudis, as well as hunting squid, cuttlefish and rays.


Battery Point Solomon Islands

Squid sometimes use divers lights to hunt. One night at Battery Point this squid caught and ate a fish in front of my eyes. I felt a bit sorry for the fish, but I was happy with the shot.

Bobbit worm. Its powerful jaws, toxic bristles and rainbow shimmer are very impressive.

Wreck of the Ann

This wreck is worth diving twice; once with a wide-angle lens to shoot the wreck, then you should come back and find all the tiny critters on the wreck itself. Soft coral crabs, nudis, and shrimps are abundant. The sandy slopes to either side are also worth exploring for crocodile fish, eels and rays.

At Bonegi Beach, a short drive from the centre of Honiara, two large Japanese WWII wrecks lay conveniently in shallow water. Starting at just a few metres depth (making them accessible to snorkelers and divers alike), each wreck is covered with amazing biodiversity; fish, shrimps, nudis, eels, rays, and diverse, healthy hard and soft corals.

Mirror Pond

This is another site with both excellent wide angle and macro opportunities.  There is a cave you can enter by swimming under the reef, and then you can surface in a beautiful pool under the jungle canopy. There used to be a resident saltwater crocodile here, but (happily for most) he’s not there any more.

Coral hermit crabs are tiny, living in holes around 6-8mm diameter. They are filter feeders, using their feathery arms to collect particles from the water.

Calm, sunny shallow hard coral gardens at Mirror Pond are a pleasure to explore.

This is the “pond” which gives the site its name. You can swim under a cut in the reef, and surface here to admire the lush green jungle above.

Maravagi is in the Florida Islands, and is best known for its dive site called “Devil’s Highway”, where divers hook onto the reef and let the fast current fly past while manta rays swim overhead. But the shallow waters just off the beach are also worth exploring; they are home to a vast array of juvenile species including baby batfish, cuttlefish, crabs, rays and scorpionfish.

Mbike is a tiny island not far from Honiara, with simple accommodation and a purposely sunk wreck just off its beach. It’s regular weekend getaway for Honiara residents.

This fishing boat wreck sits in shallow waters off the side of Mbike Island.

Nembrotha kubaryana is my all-time favourite nudi, and for some reason this wreck always has at least a dozen of them crawling around its deck.

Mbulo Caves

Mbulo Island has a series of caves cut into the reef around the island. This dive is all about the light; swimming in and out of caves, finding beams of light to shoot. A green jungle canopy lies above.
