Discover the Best Solomon Islands Diving at Leru Cut and Marovo Lagoon
The Solomon Islands sit at the edge of the Coral Triangle and remain one of the most untouched dive destinations in the South Pacific. With hundreds of remote islands and limited tourism infrastructure, this is a place where reefs thrive, wrecks rest undisturbed, and divers often feel like they are exploring entirely on their own. For anyone curious about true frontier-style exploration, Solomon Islands diving offers an experience that feels raw, authentic, and deeply rewarding.
What sets the Solomon Islands diving apart is its sheer variety. In a single trip, divers can glide through narrow island cuts filled with sunbeams, drift along walls swept by pelagic fish, and explore World War II wrecks now transformed into living reefs. Healthy hard coral coverage, dense schools of fish, and rare macro life all exist side by side, making every dive different from the last.
Liveaboard diving is the most effective way to experience this vast country. With dive sites spread across more than 11,000 sq mi of ocean, staying on a vessel allows access to regions like the Russell Islands, Florida Islands, Mary Island, and Marovo Lagoon. This introduction breaks down the highlights of Solomon Islands diving and helps you understand what to expect when planning a trip to this remarkable destination.
Rainbow Reefs and Leru Cut: A Diver’s Dream
Rainbow Reef and Leru Cut are two of the most iconic dive sites in the Solomon Islands and are often the first stops on a liveaboard tour. Located in the Russell Islands, these sites showcase both the dramatic scenery and the rich marine biodiversity that define Solomon Islands diving. Together, they offer a perfect mix of wide-angle spectacle and intricate detail.
Rainbow Reef is known for its intense fish life and vibrant coral growth. Ocean currents bring nutrients that support large schools of fusiliers, snappers, and unicornfish, while reef sharks and barracuda patrol the edges. The reef structure rises toward shallower depths, making it accessible while still delivering a sense of scale and movement that photographers love.
Leru Cut, by contrast, is all about atmosphere. This narrow channel cuts deep into Leru Island, with steep rock walls and a sandy bottom at around 40 ft. When dived at the right time of day, sunlight pours through the opening and creates dramatic beams underwater. Outside the cut, the reef wall continues with resting sharks, electric clams, and a wide range of reef fish.
What makes these sites special:
Rainbow Reef’s dense schools of reef fish and pelagic action
Leru Cut’s narrow canyon and signature light beams
Excellent balance of macro life and wide-angle opportunities
Accessible depths combined with visually dramatic terrain
Together, Rainbow Reef and Leru Cut set the tone for Solomon Islands diving by showing just how diverse and visually striking the underwater landscape can be within a small geographic area.
Marovo Lagoon: The Heart of Solomon Islands Diving
Marovo Lagoon is often considered the centerpiece of Solomon Islands diving. As one of the largest saltwater lagoons in the world, it offers an incredible range of dive environments, from sheltered coral gardens to exposed reef edges where big fish gather. Many longer liveaboard diving cruises are designed specifically to reach this region.
The lagoon is home to sites like Mbulo Island, where sharks, bumphead parrotfish, groupers, and barracuda move through clear blue water. Other locations, such as Kicha Reef, are packed with color, featuring healthy hard corals, soft corals, and an overwhelming density of reef fish. The calm conditions in parts of the lagoon also allow for long, relaxed dives with excellent visibility.
Marovo Lagoon is equally rewarding for scuba divers who enjoy smaller marine life. Pipefish, nudibranchs, pygmy seahorses, and ghost pipefish can be found among coral bommies and sea fans. This combination of large animals and fine detail makes the lagoon one of the most balanced and satisfying areas for Solomon Islands diving.
Highlights of Marovo Lagoon diving:
Large lagoon system with varied dive environments
Strong encounters with sharks, bumpheads, and schooling fish
Excellent macro life for photographers
Calm conditions ideal for extended bottom times
Above water, village visits in the Marovo region add cultural depth to the experience, making this area a true highlight of any Solomon Islands liveaboard journey.
WWII Wrecks and Historical Diving
The Solomon Islands played a major role during World War II, and the remains of that history are scattered across both land and sea. Many of the wrecks now serve as artificial reefs, blending historical significance with thriving marine ecosystems. This aspect of Solomon Islands diving is both educational and visually compelling.
Popular wrecks include the Japanese Mavis Seaplane, which rests upright on a silty bottom and is often surrounded by glassfish. The Ann freighter and the famous White Beach dump site offer a different kind of exploration, with vehicles, machinery, and debris now covered in corals and sponges. These sites are accessible to recreational divers while still offering depth and complexity.
In areas like Guadalcanal and the Florida Islands, deeper wrecks attract experienced divers looking for more challenging profiles. Many of these sites are home to large schools of fish and hunting predators, adding excitement to the historical exploration. Each wreck tells a story, making every dive feel like a journey through time.
Florida Islands: Twin Tunnels and Devil’s Highway
The Florida Islands are known for their dramatic underwater topography and higher-energy dive sites. This region adds an adventurous edge to Solomon Islands diving, with stronger currents and unique geological formations that create unforgettable dives.
Twin Tunnels is one of the most famous sites in the area. Divers descend through twin lava tubes starting around 50 ft and exiting at approximately 110 ft before reaching the outer reef wall. The tunnels open onto a wall where currents often bring in pelagic fish, while the top of the seamount features healthy coral and reef life.
Devil’s Highway offers a completely different experience. This is a drift dive where strong currents attract manta rays, sharks, and large schools of fish. Divers are carried over shallow reef tops, making it an exhilarating but controlled dive when properly planned.
Key features of Florida Islands diving:
Twin Tunnels lava tube formations
High-energy drift dives like Devil’s Highway
Pelagic encounters driven by strong currents
Variety of deep and shallow reef structures
The Florida Islands add excitement and contrast to a Solomon Islands safari, rounding out the overall diving experience.
Liveaboard Diving in the Solomon Islands
Liveaboards are the best way to experience Solomon Islands diving due to the country’s size, remoteness, and scattered dive regions. With hundreds of islands spread across thousands of square miles of ocean, liveaboard vessels allow divers to reach pristine reefs, WWII wrecks, and dramatic underwater landscapes that are not accessible from shore-based accommodations. Most trips depart from Honiara and travel through the Russell Islands, Florida Islands, Mary Island, and Marovo Lagoon.
Days onboard are built around diving efficiency and comfort. Divers typically enjoy 4 to 5 dives per day, using small tenders for easy drop-offs and pickups directly over the dive sites. Facilities such as spacious dive decks, individual gear storage, camera rinse tanks, and nitrox support longer, safer dive days. Between dives, guests can relax on deck, enjoy meals, and cruise through some of the most untouched scenery in the South Pacific.
Liveaboard trips also go beyond diving. Cultural village visits, opportunities to see traditional music and dance, and time spent interacting with local communities add an important human element to the journey. Combined with flexible tours and access to remote locations, liveaboards deliver a complete and immersive Solomon Islands diving experience.

Tips for Planning Your Liveaboard Trip
Planning a liveaboard trip to the Solomon Islands requires thoughtful preparation due to the destination’s remoteness. Understanding seasonal conditions, travel logistics, and dive requirements helps ensure a smooth and enjoyable experience.
Most liveaboard trips range from 7 to 14 nights, with longer expeditions reaching further north. While many dive sites are suitable for certified divers, advanced certification is recommended for deeper dives, wrecks, and sites with strong currents. Packing appropriately for warm water diving and multiple daily dives is also essential.
Choosing the right cruise depends on your interests, whether that is wrecks, pelagic action, macro life, or cultural experiences. Liveaboards typically offer up to five dives per day, allowing you to tailor your schedule to your energy level and goals.
Helpful planning considerations:
Choose trip length based on desired regions
Bring appropriate gear for warm water and currents
Prepare for multiple dives per day
Consider certification level when selecting itineraries
