Lighthouse Channel in the Rock Islands is a high-energy wall and reef dive suited for advanced divers. The site features a vertical drop from 5 to 45 metres, with an average depth of 25 metres. Divers must be prepared for strong currents and potential down currents along the wall face. Visibility ranges from 10 to 40 metres. Access is by boat only, and a negative entry is required to reach the reef quickly. Due to active boat traffic in the channel, the use of a surface marker buoy upon ascent is essential for safety.

Peaceful Lagoon, located in the Rock Islands of Palau, provides a forgiving environment for reef diving. The site features depths between 4 and 18 metres, making it suitable for beginners. Divers experience mild currents and visibility ranging from 15 to 30 metres. Access is exclusively by boat, with typical dives lasting around 45 minutes. Water temperatures remain consistent between 28 and 30 degrees Celsius throughout the year. Species recorded around this area include wrasses, Napoleon Wrasse, Mandarinfish, Harlequin Sweetlips, Regal Angelfish, Day Octopus, Clown Triggerfish, Giant Moray, Banded Pipefish, Rock Cod, Moorish Idol, Eightband Butterflyfish, Bluefin Trevally, and Pacific Sailfin Tang.

Mandarinfish Lake in the Rock Islands is a shallow reef site suitable for beginner divers. The site features calm, current-free conditions with depths ranging from 1 to 8 metres, averaging 5 metres. Visibility typically fluctuates between 5 and 13 metres. The location is primarily accessed by boat, and guided tours are available to assist with navigation. Night diving is the main activity here, with boat departures timed to arrive at the reef just before dusk. Dives typically last around 50 minutes. Due to the nature of the site, small group sizes are maintained to minimise disturbance to the reef environment.

The Nagisan Maru is a wreck dive located in the Rock Islands of Palau, resting at depths between 26 and 33 metres. This site is strictly for advanced divers due to the depth and potential for entanglement within the structure. Access is by boat only, and divers should be prepared for mild currents and visibility ranging from 5 to 15 metres. Given the depth, careful dive planning is essential to manage bottom time and nitrogen narcosis risks. Divers are advised to carry primary and backup torches for penetration and to avoid all contact with the wreckage to ensure safety.

Sata is a wreck dive located in the Rock Islands of Palau, resting at depths between 18 and 37 metres. Access is strictly by boat, and the site is suited for intermediate divers due to the depth and potential for decompression. Visibility typically ranges from 10 to 20 metres, with water temperatures remaining between 28 and 30C. Mild currents are common, but divers must remain vigilant regarding depth control and entanglement risks within the wreck structure. Guided tours are recommended to navigate the layout effectively and manage bottom time safely. Divers should carry a knife and possess appropriate wreck training before attempting penetration.

Hafa Dai is a wreck dive located in the Rock Islands of Palau, resting at depths between 15 and 30 metres. The site is accessible only by boat and features mild currents, making it suitable for beginner divers. Visibility typically ranges from 5 to 10 metres, requiring divers to stay close to the structure. As an overhead environment, the wreck presents risks including entanglement and sharp metal edges. Divers should maintain buoyancy control and follow their guide to avoid enclosed sections where silt disturbance could limit visibility. Water temperatures remain consistent between 28 and 30 degrees Celsius, supporting a typical dive duration of 40 minutes.

The Iro Maru is a Japanese WWII fuel tanker resting on a sandy bottom in the Rock Islands. The wreck structure begins at 8 metres and extends to a maximum depth of 40 metres, with an average depth of 27 metres. Access is by boat only. Divers encounter mild currents that can strengthen, and visibility varies between 10 and 30 metres. The site presents significant overhead environments and entanglement hazards, requiring advanced and wreck diving qualifications. Due to the depth and potential for low light within the hull, carrying a primary and backup torch is essential for all penetration dives. Night diving is permitted at this location.

ZEKE Zero is a wreck dive located in the Rock Islands of Palau, resting at depths between 9 and 17 metres. The site is accessible by boat and features moderate currents, with visibility ranging from 15 to 30 metres. The wreck provides an overhead environment, requiring caution and appropriate training for any penetration beyond natural light. Water temperatures remain consistent between 28 and 30 degrees Celsius. Divers should maintain awareness of boat traffic when surfacing. While species recorded around this area include wrasses, groupers, and various reef fish, the wreck itself serves as a structure for marine life in the region.
