Tunku Abdul Rahman Marine Park

Kota Kinabalu · Sabah · Malaysia

Tunku Abdul Rahman Marine Park comprises five islands lying just off the coast of Kota Kinabalu, Sabah's capital city on the island of Borneo. What makes this park remarkable is its accessibility — a 15-minute speedboat ride from the city center drops you on reefs that harbor a surprising wealth of marine life for a site within sight of a modern Asian city's skyline. The park encompasses Gaya, Sapi, Manukan, Mamutik, and Sulug islands, each with its own reef character and dive profiles. Descending on the southern reef of Mamutik Island, I immediately spotted a bamboo shark resting under a coral table, its striped juvenile coloring vivid against the white sand. These small, docile sharks are a signature species here, found tucked under ledges and in crevices throughout the park. Moving along the reef slope, the coral diversity becomes apparent — over 250 species of hard coral have been recorded in the park, creating a mosaic of textures and colors that supports a dense community of reef fish. Frogfish sit motionless on sponges, their warty bodies requiring a guide's trained eye to spot. Leaf scorpionfish sway gently in the current, perfectly mimicking dead leaves among the coral rubble. Nudibranchs in psychedelic colors crawl across every surface, making this a productive site for macro photography despite the moderate visibility. The park's reefs have benefited enormously from fishing restrictions enforced since its gazetting in 1974, and ongoing coral rehabilitation projects are restoring damaged sections. Night dives in the park reveal a different world, with hunting cuttlefish, prowling octopuses, and the emergence of cryptic species that hide during the day. Blue-spotted stingrays glide across sandy patches between coral heads, and pipefish emerge from their daytime shelters to feed in the open. While Tunku Abdul Rahman Park cannot compete with the crystal waters of Sipadan or the pelagic action of Layang-Layang, it offers something neither of those remote sites can: genuine reef diving that fits into a lunch break, making it one of the most accessible marine parks in all of Southeast Asia.
