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.

Kwaj-2 Coral Head is a reef and pinnacle site located within Kwajalein Atoll. This shore-accessible location offers a sheltered environment suitable for beginner divers looking to gain experience on a reef structure. Divers navigate depths ranging from 13 to 28 metres. Water temperatures remain consistent throughout the year, typically between 28 and 30 degrees Celsius. Conditions such as visibility and currents can be variable, so it is essential to check local reports before entering the water. As there are no confirmed facilities on-site, divers should arrive self-sufficient with all necessary equipment and water. Always monitor your surroundings and follow guide instructions during your dive.

Kwaj-1 Coral Head is a reef pinnacle in Kwajalein Atoll that rises from a depth of 36 metres to a shallow 5 metres. Divers typically experience 30 metres of visibility, allowing for clear views of the structure. The site requires boat access and is suited for intermediate divers due to moderate currents that can accelerate unexpectedly. Water temperatures remain warm, ranging from 28 to 30C. Marine life recorded here includes wrasses, spiny lobster, pufferfish, and various angelfish species such as the Flame and Japanese Pygmy Angelfish. Divers may also encounter sharks, scorpionfish, and reef stonefish. Use caution regarding sharp coral and boat traffic during entries.

R-Buoy Coral Head is a reef site located in Kwajalein Atoll, Marshall Islands. The topography features a coral head that drops from 8 metres to 25 metres, with an average depth of 14 metres. Divers can expect moderate currents and visibility ranging from 10 to 30 metres. Water temperatures remain consistent between 28 and 30 degrees Celsius throughout the year. Due to the presence of sharks, sharp coral, and moderate currents, this site is suited for intermediate divers with strong buoyancy control. Access is possible via boat or shore, though divers must remain alert for boat traffic and deploy a surface marker buoy when surfacing.

SAR Coral Head in Kwajalein Atoll offers a reef structure that descends from a shallow 5-metre top to a maximum depth of 50 metres. Divers typically experience mild currents and visibility ranging from 15 to 30 metres. The site is accessible via shore entry, with a dive shop and air fills available on-site. Marine life recorded at this location includes wrasses, groupers, manybar goatfish, and various snails. Divers may also encounter the pink skunk anemonefish, twoband anemonefish, and the triple-banded split-tooth dorid. Sharks are present at this site and require diver awareness. The site is suited for intermediate divers, with an average depth of 30 metres and typical dive times of 45 minutes.

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.

Bravo Buoy in Kwajalein Atoll offers a dual-environment experience, featuring both natural reef formations and artificial reef structures. This site is suitable for intermediate divers who can manage variable currents and shifting visibility. Water temperatures remain consistent between 28 and 30 degrees Celsius throughout the year. Access is exclusively by boat, and divers should coordinate with local operators to confirm conditions before departure. When navigating the site, maintain buoyancy to avoid contact with sharp coral and the rough edges of the artificial structure. Be mindful of potential jellyfish in the water column and exercise caution near the seabed to avoid sea urchins.

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.
