Twin Peaks in Kwajalein Atoll features a reef starting at 5 metres that transitions into a wall dropping to 45 metres. This site is suited for intermediate divers, offering a varied profile with visibility ranging from 15 to 40 metres. Moderate currents are common, which can accelerate along the wall face. Divers should maintain buoyancy control to avoid sharp coral and rock edges. Water temperatures remain stable between 28 and 30 degrees Celsius throughout the year. The site is accessible by both shore and boat, and night diving is permitted. Divers should be aware of the presence of sharks and the potential for changing current conditions.

Kwaj-3 Coral Head is a reef and pinnacle site located within Kwajalein Atoll. The topography features a shallow reef top that transitions into a pinnacle, offering a depth range between 5 and 50 metres with an average of 25 metres. Divers can expect mild currents and visibility ranging from 20 to 40 metres. Marine life recorded at the site includes Napoleon Wrasse, Twoband Anemonefish, Blackspotted Pufferfish, and various wrasses, alongside invertebrates such as Goniobranchus kuniei, Flamingo Tongue, sea stars, and hermit crabs. This shore-entry site is suitable for intermediate divers. Due to local boat traffic, the use of a surface marker buoy is essential for all ascents.

Victor Buoy Coral Head is a reef site in Kwajalein Atoll that extends from the shallows to a depth of 50 metres, with an average depth of 25 metres. The site offers consistent visibility of 30 metres, allowing for clear observation of the reef structure. Access is by boat only, as the shore features strong surf and shore breaks. Divers should be prepared for moderate and shifting currents throughout the dive profile. It is recommended to plan entries around slack water and monitor conditions closely. As there are no permanent support services at the atoll, divers must be self-sufficient and confirm all logistics locally before arrival.

T-Buoy Coral Head is a reef site located within the sheltered waters of Kwajalein Atoll. Accessible directly from the shore, the site features a central coral head that serves as the primary focal point for divers. Conditions are generally warm, with water temperatures ranging between 28 and 30 degrees Celsius throughout the year. Divers should be prepared for a moderate current that requires careful positioning on the reef. Entry requires caution due to sharp rocks along the shoreline, and appropriate footwear is recommended. This site is suited for intermediate divers who can manage current flow during a shore-based dive.

S-Buoy Coral Head is an exposed reef site in Kwajalein Atoll, accessible only by boat. The topography features a coral head ranging from 5 to 36 metres, allowing divers to transition from shallow reef exploration to deeper sections during a single 45-minute dive. Visibility typically spans 20 to 40 metres. Divers should expect moderate currents that may strengthen unexpectedly, necessitating careful planning and the use of a surface marker buoy. Hazards include sharks and potential entanglement risks within the reef structure. Water temperatures remain stable between 28 and 30 degrees Celsius. Always confirm local base access and facility availability before planning a trip to this site.

Vertical Wall in Kwajalein Atoll is a steep reef drop-off that descends rapidly from the reef crest. Divers experience an expansive, open-water environment with visibility typically ranging between 30 and 40 metres. Water temperatures remain consistent, fluctuating between 28 and 30 degrees Celsius throughout the year. This site is accessible only by boat, and the moderate currents require intermediate buoyancy skills and constant situational awareness. Because the floor drops quickly from 2 to 30 metres, divers must monitor their depth gauges continuously. Due to the presence of sharks and potential for strengthening currents, divers should establish a clear drift plan and surface-marker procedure with the boat crew before entry.

North Loi Coral Head in Kwajalein Atoll is a shallow reef accessible directly from the shore. The site is suitable for beginners, though divers should remain aware of moderate currents and navigate carefully to avoid contact with sharp coral and rocks. Water temperatures remain stable between 28 and 30 degrees Celsius throughout the year. Marine life recorded at this site includes the painted frogfish, day octopus, zebra lionfish, and various nudibranch species such as Chromodoris and Tryon's Hypselodoris. Divers may also encounter wrasses, triggerfish, mantis shrimp, and pink skunk anemonefish. Always check with local staff regarding current visibility and entry conditions before planning a dive.

Troys Coral Head is a reef pinnacle located in the Kwajalein Atoll, featuring a structure that ranges from a shallow 5-metre cap down to 50 metres. The site is accessed exclusively by boat, with divers entering the water directly from the vessel. Visibility is consistently 30 metres, while water temperatures remain between 28 and 30 degrees Celsius. Due to variable currents and depths reaching 50 metres, this site is suited for intermediate divers with strong buoyancy control. Divers should exercise caution regarding sharp coral and rocks on the reef structure and maintain a safe distance from sharks present in the area.
