Mabul Island off Sabah's east coast sits at the heart of Borneo's macro diving industry, where resident Bargibant's and Denise's pygmy seahorses on sea fans and artificial reefs are a daily headline critter on guided muck dives. Operators like Scuba Junkie and Borneo Divers run year-round two-tank days across sandy slopes, the Seaventures oil-rig platform, and house reefs packed with frogfish, blue-ringed octopus, and ghost pipefish. April through October brings the calmest seas and the densest critter activity on this Sipadan gateway island.
