Apo Reef is a remote marine site offering a combination of wall, reef, and drift diving. Located 30 kilometres from shore, this site requires boat access and is suited for intermediate divers. Depths typically range from 20 to 40 metres, with an average of 25 metres. Divers should be prepared for moderate currents and visibility that fluctuates between 10 and 30 metres. Due to the depth and potential for shifting currents, divers must maintain strict buoyancy control and monitor decompression limits closely. Surface marker buoys are recommended for all dives, and it is essential to brief thoroughly with a guide regarding current conditions before descending.

Southeast Corner at Apo Reef is a reef and wall dive featuring depths between 3 and 40 metres, with an average depth of 24 metres. This site is accessed by boat and typically involves a drift dive due to moderate currents. Visibility ranges from 10 to 25 metres. Marine life recorded here includes wrasses, Harlequin Sweetlips, Foxface Rabbitfish, unicornfish, elongate clams, groupers, emperor, sea cucumbers, and sea squirts. Divers should be aware of sharks and strong currents, particularly along the deeper wall sections. Due to the potential for accelerating currents and the deep nature of the site, it is suited for intermediate divers who can maintain good buoyancy and stay close to their guide.

Mabuti is a reef dive site located at Apo Reef in the Philippines. Accessible only by boat, this site features shallow water and a reef structure suitable for intermediate divers to practise buoyancy control. Conditions at the site are variable, with currents that can shift between visits, requiring divers to check conditions with their boat operator before descending. Water temperatures remain consistent throughout the year, ranging between 29 and 31 degrees Celsius. As facilities at this location are unverified, divers should confirm all necessary equipment and surface support requirements with local operators prior to departure.

Ego Wall is a wall and reef site located at Apo Reef, Philippines, featuring a drop-off that extends from 5 metres to 30 metres. Divers access the site by boat, experiencing visibility between 15 and 30 metres. While currents are typically mild, the site is subject to surges that require careful buoyancy management and close proximity to the wall. Water temperatures remain consistent between 28 and 31 degrees Celsius. Due to the potential for changing conditions, this site is suited for intermediate divers. Species recorded around this area include the giant moray, varicose wart slug, and painted spiny lobster.

Shark Airport is a reef site located at Apo Reef, Philippines, characterised by a consistent depth of 20 metres. Access is strictly by boat, and the site is suited to intermediate divers who are comfortable managing moderate currents. Visibility at the site fluctuates between 10 and 35 metres. Water temperatures remain stable throughout the year, ranging from 27 to 30 degrees Celsius. Due to the depth and current conditions, this site is intended for scuba diving rather than snorkelling. Divers should ensure their descent is timed with slack or manageable water flow to maximise bottom time and maintain effective buoyancy control.

Manta Point is a reef site within the Apo Reef system, featuring depths ranging from 5 to 30 metres with an average of 18 metres. The topography includes a reef structure that transitions into open water at the edge, where currents often increase. Divers should expect moderate currents throughout the dive, requiring good buoyancy control. Visibility varies from 7 to 30 metres. Access is by boat only, and the site is suited for intermediate divers. Hazards include sharp coral, rocks, and sea urchins on the reef floor. Species recorded around this area include Napoleon Wrasse, Giant Trevally, Whitetip Reef Shark, and various moray eels.

Jack's Point is a shore-entry reef dive located at Apo Reef, Philippines. The site features shallow, calm water, making it a practical choice for newer divers. Water temperatures remain warm throughout the year, ranging from 29 to 31 degrees Celsius, requiring minimal thermal protection. Current conditions are variable and should be assessed before entry. Visibility can shift depending on conditions, with early morning often providing the clearest water. As there are no facilities on site, divers must bring all necessary equipment, water, and first aid supplies. Reef-safe footwear is recommended for the shore entry walk.

Apo 29 is a deep wall site at Apo Reef, Philippines, that drops from 29 metres to over 150 metres. This site is strictly for advanced divers due to the extreme depths and strong, variable currents. Visibility typically ranges between 15 and 50 metres, allowing for expansive views of the wall topography. Access is by boat only, and divers must coordinate descent and pick-up points with the skipper due to the challenging drift conditions. Water temperatures remain consistent between 26 and 28 degrees Celsius throughout the year. Given the depth and current, this site requires precise buoyancy control and is not suitable for casual exploration.
