Solomon Islands: The Ultimate Diving Destination

In a world where "untouched" and "undiscovered" have become overused marketing terms in dive tourism, the Solomon Islands remains one of the few destinations that genuinely deserves these descriptions. Located in the Coral Triangle—the global epicenter of marine biodiversity—this archipelago of nearly 1,000 islands offers divers a rare combination of pristine coral ecosystems, dramatic underwater topography, and one of the world's most significant collections of accessible WWII wrecks.

Having explored diving destinations across the globe for over two decades, I can confidently say that the Solomons represents one of the last true diving frontiers. With just a few thousand divers visiting annually (compared to millions in more established destinations), you'll rarely share a dive site with another group, allowing for marine encounters that feel like genuine discoveries rather than choreographed experiences.

Unparalleled Marine Biodiversity

The Solomon Islands sits within the Coral Triangle, home to more than 75% of the world's known coral species and over 3,000 species of fish. This positioning at the heart of marine biodiversity creates an underwater environment of extraordinary richness and variety. What makes the Solomons particularly special is that this biodiversity remains largely intact, with minimal impacts from mass tourism, industrial fishing, or widespread coral bleaching that have affected more visited destinations.

On a typical dive here, you can expect to encounter:

  • Pristine hard and soft coral gardens with near-100% coral coverage in many sites
  • Macro photography paradise with nudibranchs, pygmy seahorses, and countless crustacean species
  • Pelagic action including barracuda, tuna, reef sharks, and occasional hammerheads
  • Rare species such as the Melanesian wrasse, wolf cardinalfish, and pink-eyed goby that are endemic to the region
  • Marine mammals including dolphins and dugongs in certain locations

Most remarkable is the sheer density of life—dives where every square meter of reef supports dozens of species in a complex ecological tapestry. This biodiversity extends from shallow reef flats perfect for snorkelers to deep walls disappearing hundreds of meters into the abyss.

World War II Underwater Museum

Between 1942 and 1943, the waters around the Solomon Islands, particularly those surrounding Guadalcanal and the Florida Islands, became the graveyard for dozens of American and Japanese ships and aircraft during the Pacific War. Today, these wrecks constitute one of the world's greatest concentrations of accessible WWII maritime artifacts—a somber yet fascinating underwater museum.

The most famous area, nicknamed "Iron Bottom Sound" between Guadalcanal, Savo, and Florida Islands, contains nearly 50 major shipwrecks—some in recreational diving depths, others requiring technical diving certification. Among the most notable wrecks accessible to recreational divers are:

Iconic Wreck Dives

  • USS Aaron Ward: This 348-foot destroyer rests in 40-70 meters near Honiara, largely intact with gun turrets and depth charge racks still visible. (Advanced/Technical diving)
  • Hirokawa Maru: A 155-meter Japanese transport ship sitting upright in 30-57 meters, featuring intact holds still containing vehicles, ammunition, and aircraft parts.
  • Bonegi 1 & 2 (Hirokawa Maru and Kinugawa Maru): These accessible shore dives near Honiara are perfect for both novice wreck divers and photographers, with sections breaking the surface.
  • I-1 Submarine: This Japanese submarine lies in shallow water (8-28 meters) near Tambea, broken in two sections but with conning tower, deck gun, and torpedo tubes still clearly identifiable.
  • F4F Wildcats and A6M Zeros: Multiple aircraft wrecks dot the seabed, some remarkably intact despite over 75 years underwater.

What distinguishes these wrecks from those in more frequented destinations is both their historical significance and their preservation state. The remote location and limited diving traffic have meant less souvenir-taking and damage, leaving artifacts like personal items, instruments, and weaponry in situ—creating a more authentic historical experience.

Regional Diving Highlights

The Solomon Islands comprises multiple diving regions, each with distinctive underwater environments worth exploring:

Western Province

Centered around Gizo, Munda, and the Marovo Lagoon (the world's largest saltwater lagoon), this region offers:

  • Grand Central Station: A convergence of currents that attracts schooling pelagics and reef sharks
  • Kennedy Island: Named after JFK who swam here after PT-109 was sunk, featuring excellent fringing reefs
  • Shark Point: Reliable encounters with blacktip and whitetip reef sharks
  • Alice in Wonderland: A psychedelic explosion of soft corals and sea fans
  • Custom Cave: A large cavern with dramatic light effects and resident batfish

Central Province and Honiara

The historical heart of Solomon Islands diving, focused on WWII wrecks:

  • Iron Bottom Sound: The epicenter of Pacific War maritime wrecks
  • Tulagi Harbor: Multiple Japanese shipwrecks and PT boat wrecks in relatively shallow water
  • Twin Tunnels: A unique geological formation with two parallel swim-throughs encrusted with soft corals
  • Bonegi Beach: Shore-accessible shipwrecks perfect for both snorkelers and divers

Malaita and Remote Eastern Islands

Less visited but offering spectacular diving for those willing to venture further:

  • Duff Reef: Pristine hard coral gardens with exceptional clarity
  • Langa Langa Lagoon: Famous for artificial islands built on coral foundations by ancestors of today's residents
  • Star Harbour: Remote eastern area with virgin reefs and traditional fishing communities

Practical Information for Divers

When to Go

The Solomon Islands can be dived year-round, but conditions vary seasonally:

  • April to November: Dry season with best overall diving conditions
  • July to August: Peak season with lowest rainfall and best visibility (often exceeding 30 meters)
  • December to March: Wet season brings more rain and occasionally reduced visibility but fewer visitors

Water temperatures remain comfortable throughout the year, typically ranging from 28-30°C (82-86°F), eliminating the need for thick wetsuits—most divers are comfortable in 3mm suits or even rashguards for multiple daily dives.

Diving Infrastructure

Unlike mass tourism destinations, diving in the Solomons maintains a small-scale, personalized character:

  • Dive Resorts: Several dedicated dive resorts offer packages with daily boat trips to nearby sites
  • Liveaboards: Limited but high-quality liveaboard options provide access to more remote regions
  • Dive Shops: Found in provincial centers like Honiara, Gizo, and Munda, offering equipment rental, guided dives, and courses

Most operations are small, owner-operated businesses with deep local knowledge and a focus on personalized service. This means smaller groups, flexible itineraries, and diving tailored to your interests and experience level rather than rigid schedules designed for mass tourism.

Equipment and Facilities

While the Solomon Islands offers world-class diving, it's important to set appropriate expectations regarding facilities:

  • Equipment: Most reputable operations maintain good quality rental gear, but variety and sizes can be limited—bring your own mask, computer, and specialized items if possible
  • Air/Nitrox: Standard air fills are universally available; Nitrox is available at major dive centers and on liveaboards but not everywhere
  • Camera Facilities: Basic rinse tanks and charging stations exist, but bring extra batteries, memory cards, and any specialized maintenance tools
  • Technical Diving: Limited support exists for technical diving outside dedicated trips—advanced planning is essential

The tradeoff for fewer amenities is diving sites virtually to yourself and experiences unmatched in more developed destinations.

Conservation and Sustainable Diving

The pristine nature of Solomon Islands reefs stems partly from traditional marine resource management practiced by coastal communities for generations. Many dive sites operate under customary ownership, with local villages maintaining control over access and establishing their own conservation measures.

As visitors to these special environments, divers have responsibilities:

  • Respect local arrangements: Dive operators pay fees to local communities for access to many sites—understand that these arrangements support conservation and local livelihoods
  • Perfect buoyancy: Many sites feature delicate soft corals and reef structures that can be damaged by careless finning or contact
  • Artifact ethics: While the temptation to collect "souvenirs" from wrecks may be strong, removing items damages historical integrity and may be illegal
  • Plastic reduction: Waste management infrastructure is limited in the Solomons—minimize single-use plastics during your visit

Several community-based marine protected areas have been established throughout the archipelago, often in partnership with dive operators and conservation organizations. These initiatives demonstrate how sustainable dive tourism can contribute to both conservation and community development.

Beyond the Diving: Cultural Experiences

What makes a diving trip to the Solomon Islands particularly rewarding is the cultural dimension that complements the underwater experiences. Unlike destinations where diving and cultural activities feel disconnected, here they're interwoven—many dive sites are directly linked to local communities, traditional practices, and historical narratives.

Between dives, consider these experiences:

  • Village visits: Many dive resorts arrange respectful visits to nearby communities where you can learn about traditional crafts, music, and daily life
  • War memorials and museums: Sites commemorating the Guadalcanal Campaign provide historical context for the wrecks you'll dive
  • Traditional navigation: In some areas, you can learn about the star-based navigation techniques that allowed Melanesian peoples to traverse vast ocean distances for centuries
  • Shell money: The production of traditional currency from shells continues in places like Langalanga Lagoon in Malaita

Understanding the cultural context enhances the diving experience by connecting underwater landscapes to the people who have lived alongside them for generations. This cultural dimension is particularly valuable for non-diving companions, who can enjoy meaningful experiences while divers are underwater.
