Kota Kinabalu's diving is centred on two distinct areas: the island reefs of Tunku Abdul Rahman Park, which account for the great majority of sites, and the quieter Usukan Bay to the north. Boat-access reef diving dominates, with sites ranging from shallow coral gardens suited to beginners through to drift dives, pinnacles, walls, and a deep wreck for more experienced divers. The marine life is rich and observation-backed, with Common Clownfish, Blackspotted Pufferfish, Titan Triggerfish, and multiple lionfish species recorded across nearly every site.

Water temperature stays warm throughout the year, with the coolest months falling around February and March and the warmest period running from July through December. The best-months data points strongly to March, April, May, and October as the peak periods for conditions, likely reflecting calmer seas and improved visibility. Currents are generally mild across most sites, though drift sites such as Mayne Reef, North Hill, and Ella's Garden benefit from a little more experience.

The reefs here support a wide range of observed species. Titan Triggerfish, Blackspotted Pufferfish, and Common Clownfish are recorded across virtually every site. Zebra Lionfish, Spotfin Lionfish, and Bluespotted Fantail Ray are also very commonly sighted, alongside Giant Moray, Harlequin Sweetlips, and Bluestreak Cleaner Wrasse. Whale Shark and Green Sea Turtle are listed as signature species for the region.
The majority of dive sites here are rated for beginners, including popular spots such as Agyll's Reef, Nudi Garden, Peaceful Garden, and North Hill. Depths at many sites are shallow enough to be forgiving, and currents are generally mild. More experienced divers can progress to intermediate sites like Leopard Reef or the deeper Rice Bowl Wreck, which is rated for advanced divers.
Tunku Abdul Rahman Park contains the vast majority of sites and offers the widest variety of dive types, from shallow coral gardens and drift dives to a wreck and pinnacle. Usukan Bay, to the north, has a smaller number of sites and provides a quieter alternative for those looking to explore beyond the main island cluster.
All listed sites are boat-access only, with no shore entries recorded in the data. A range of operators based in the area run trips to the islands, including Downbelow Marine and Wildlife Adventures, Scuba Junkie KK, Bigfin Divers, and several others. Booking through a local operator is the standard way to reach the sites.
