Day Trips
We often do a combination of two sites in one day, so morning and afternoon are in different places. Listed below are some of the dive sites included in a dive package price and visited on a rotational basis.
- Hirokawa Maru: Also known as Bonegi 1, it was a 6,860-ton Japanese vessel that beached during the Battle of Guadalcanal and subsequently sank after being subjected to heavy bombing by the US Air Force. The wreck has become a reef hosting diverse corals, fish, and other marine organisms.
- Kyushu Maru: A Japanese transport ship that lies in Iron Bottom Sound, a stretch of water named for the numerous ships and aircraft sunk there. The wreck is encrusted with corals and sponges, attracting a diverse array of marine life, including schools of snappers, fusiliers, trevally, lionfish, nudibranchs, and anemonefish.
- Twin Tunnels: This large seamount features two tunnels that drop vertically and exit into a cave. Swimming out of the cave to the sheer wall, you’ll encounter schools of fusiliers and grey reef sharks cruising by.
- Tanavula Point: A gently sloping reef offering encounters with pelagics like eagle rays, dogtooth tuna, and occasional sharks, making it suitable for both novice and advanced divers.
- Maravagi Bay: A macro divers delight! A calm protected bay offering all sorts of great macro subjects.
- USS Aaron Ward: A technical dive, the Aaron Ward has become an artificial reef, attracting diverse marine life and offering a poignant glimpse into naval history. Divers can observe the ship’s armaments, including its 5-inch guns still pointing skyward, and other features that testify to its final battle.
Azumasan Maru: Another tech dive, a freighter requisitioned by the Imperial Japanese Navy during World War II, it was deliberately beached but still sank into Iron Bottom Sound. The wreck now lies upright on the seabed, with the bow at approximately 39m and the stern descending to nearly 90m.

I-1 Submarine Wreck
The I-1 Japanese submarine cruiser was sunk on 29 January 1943 during a confrontation with the Royal New Zealand Navy's minesweepers, HMNZS Kiwi and HMNZS Moa, near Kamimbo Bay. After sustaining damage from depth charges and gunfire, the I-1 was forced to run aground on a reef, where it ultimately sank. The wreck is partially intact. In 1972, an attempt to salvage valuable metals resulted in an explosion that destroyed the forward third of the submarine. The remaining structure has become an artificial reef, hosting diverse marine life.
Solsea
This site features the remains of an island trader vessel that was intentionally scuttled onto a reef. The ship now rests upright on an incline, with its bow pointing skyward, creating a striking underwater silhouette.
The wreck has become a thriving artificial reef, attracting a diverse array of marine life. Divers can expect to encounter schools of Spanish mackerel and rainbow runners near the surface, while deeper sections of the wreck are frequented by coral trout and red emperor. The site offers depths ranging from 18 to 40 meters, making it suitable for advanced divers seeking both historical intrigue and rich biodiversity.
USS Serpens
The USS Serpens (AK-97) was a U.S. Navy cargo ship manned by the Coast Guard during World War II. On 29 January 1945, while anchored off Lunga Beach on Guadalcanal in the Solomon Islands, the vessel suffered a catastrophic explosion during the loading of depth charges. This tragic incident resulted in the deaths of 196 Coast Guard crewmen, 57 Army stevedores, and a Public Health Service physician, marking it as the largest single disaster in U.S. Coast Guard history.
The cause of the explosion was never definitively determined. Initially attributed to enemy action, a subsequent court of inquiry concluded that the explosion was likely due to an accident intrinsic to the loading process.
The wreck of the USS Serpens lies in Ironbottom Sound, a body of water named for the numerous ships and aircraft lost during the Guadalcanal Campaign.
As a war grave, the USS Serpens wreck is a solemn site, and diving activities are subject to restrictions to honor the memory of those who perished.
USS John Penn
The USS John Penn (APA-23) was a U.S. Navy attack transport ship that met its fate during World War II. On 13 August 1943, while anchored off Lunga Point near Honiara, Guadalcanal, the vessel was struck by a Japanese aerial torpedo, leading to its sinking. The wreck now rests in Ironbottom Sound, a body of water named for the numerous ships and aircraft lost during the Guadalcanal Campaign.
The USS John Penn has become an artificial reef, attracting a diverse array of marine life. Divers exploring the site can expect to encounter schools of fish and vibrant coral growths that have colonized the wreck over the decades. The combination of historical significance and marine biodiversity makes it a compelling dive for those with the requisite experience.
Please note that the wreck is considered a war grave, and divers are expected to treat the site with respect.
Azumasan Maru
The Azumasan Maru was a Japanese freighter built in 1933 and later requisitioned by the Imperial Japanese Navy during World War II. In October 1942, while attempting to resupply Japanese forces on Guadalcanal, the ship was attacked by U.S. aircraft. After sustaining significant damage, it was beached near Bunani Point to prevent sinking. However, further bombing on October 16 caused it to slip off the reef and sink into Ironbottom Sound. The wreck now lies upright on the seabed, with the bow at approximately 39 meters and the stern descending to nearly 90 meters.
Sasako Maru
On 15 October 1942 the Sasako Maru was attacked by U.S. aircraft while unloading troops and supplies near Bunani Point. After sustaining damage, it was deliberately beached, but subsequent bombing caused it to slip off the reef and sink into Ironbottom Sound. The Sasako Maru has become an artificial reef, attracting diverse marine life. Divers can explore the intact structure, which offers a unique glimpse into World War II history.
USS Aaron Ward
The USS Aaron Ward (DD-483) was a Gleaves-class destroyer of the United States Navy, notable for its service during World War II. On 7 April 1943, while escorting landing craft near Guadalcanal, the ship was attacked by Japanese aircraft during Operation I-Go. Despite valiant efforts to defend and save the vessel, it sustained multiple bomb hits, leading to its sinking off Tinete Point near Nggela Pile (Small Gela) in the Florida Islands.
The wreck has become an artificial reef, attracting diverse marine life and offering a poignant glimpse into naval history. Divers can observe the ship's armaments, including its 5-inch guns still pointing skyward, and other features that testify to its final battle.
USS Kanawha
The USS Kanawha (AO-1) was the U.S. Navy’s first purpose-built fleet oiler, commissioned in 1915. On 7 April 1943, while departing Tulagi Harbour in the Solomon Islands, she was attacked by Japanese dive bombers during Operation I-Go. Sustaining multiple bomb hits, including one that ignited her forward oil tank and another that disabled her engine room, the Kanawha was engulfed in flames. Despite efforts to save her, she was beached west of Tulagi but eventually slid into deeper waters and sank by the next morning, resulting in the loss of 19 crew members.
The USS Kanawha offers a compelling dive for experienced technical divers. The wreck is largely intact, with notable features including her twin 5-inch guns at the bow, remnants of anti-aircraft weaponry, and sections of the superstructure. The site is adorned with marine life and coral growth, providing both historical significance and underwater beauty.
HMNZS Moa
The HMNZS Moa (T233) was a Bird-class minesweeper of the Royal New Zealand Navy, commissioned in August 1941. On 7 April 1943, while refueling from the USS Erskine M. Phelps in Tulagi Harbour, the Moa was attacked by Japanese dive bombers. Sustaining two direct hits, the vessel sank within minutes, resulting in the loss of five crew members.
The wreck of HMNZS Moa has become a popular dive site, offering a poignant glimpse into World War II history. Divers can observe the ship's 4-inch gun at the bow and depth charge racks at the stern.
