The Hirokawa Maru, also known as Bonegi 1, is a prominent shipwreck dive site located off the Honiara Coast. This artificial reef offers a varied profile, with depths ranging from 5 to 58 metres and an average depth of 15 metres. Divers can access the wreck via shore or boat. Conditions are variable, with visibility fluctuating between 5 and 30 metres. Due to the depth and the nature of the structure, the site presents hazards including decompression risks, nitrogen narcosis, and potential entanglement. It is best suited for intermediate divers. Facilities at the site include parking and the availability of guided tours.

The Japanese Sub I21 is a wreck located off the coast of Honiara, Solomon Islands. Resting at depths between 15 and 27 metres, the submarine is accessible directly from the shore. Divers encounter mild currents and visibility ranging from 10 to 30 metres. The site is suitable for beginner divers, though caution is required due to sharp metal on the wreck structure and sharp coral on the seabed. Divers should maintain buoyancy control to avoid entanglement and contact with hazards. Water temperatures remain consistent throughout the year, typically between 29 and 30 degrees Celsius.

Tembea Caves is a shallow cave and reef system located 70 metres offshore from Honiara. The site features depths between 5 and 10 metres and is accessible by boat or from the shore. Divers and snorkellers encounter an overhead environment that requires careful buoyancy control and awareness. Visibility is limited to approximately 5 metres and can be affected by surge and swell. While currents remain mild, the combination of low visibility and the cave structure makes this site suitable for intermediate divers with cavern certification. Water temperatures are consistent throughout the year, ranging from 29 to 30 degrees Celsius.

The Mavis Wreck Area in Iron Bottom Sound features a collection of World War Two aircraft and shipwrecks resting on the seabed. Depths range from 3 to 130 metres, with an average of 30 metres, requiring divers to match their certification level to the specific wreck. Visibility typically spans 10 to 30 metres, and water temperatures remain between 27 and 29 degrees Celsius. Access is available via both shore and boat. Due to risks including entanglement, overhead environments, strong currents, and boat traffic, guided tours are essential. Divers should monitor currents carefully and plan for controlled ascents.

The Mavis Wreck is a World War Two-era flying boat resting at depths between 28 and 32 metres. This site is suitable for intermediate divers with wreck certification. Access is exclusively by boat, and divers should confirm mooring arrangements to avoid damaging the structure. Visibility varies from 10 to 30 metres, and the site features mild currents. Divers should be aware of entanglement risks and the overhead environment associated with the wreck. A torch and line cutter are recommended for all dives. Typical dive times are around 40 minutes, with water temperatures consistently between 29 and 30 degrees Celsius.

Nembelau is a wreck dive site located in the Florida Islands of the Solomon Islands. The site sits at a consistent depth of 14 metres. Access to this location is by boat only. Divers should be prepared for moderate currents at this site. Due to the nature of the wreck, entanglement is a potential hazard, and the site is recommended for intermediate divers. Water temperatures remain stable throughout the year, typically ranging between 29C and 30C.
