Tunku Abdul Rahman Marine Park
Overview
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.

Frequently asked questions
Is diving good this close to a major city?
Surprisingly yes. Marine park protection has maintained reef health despite the proximity to Kota Kinabalu. Visibility is not on par with Sipadan, but the coral diversity and critter density are genuinely impressive. The park benefits from strong tidal flushing that brings cleaner water from offshore, and enforcement of fishing restrictions has allowed fish populations to recover.
Which island has the best diving in the park?
Mamutik Island and Sulug Island generally offer the best conditions. Mamutik has excellent coral gardens on its southern side with reliable bamboo shark sightings, while Sulug is the most remote island with less diver traffic and healthier reefs. Sapi and Manukan islands are more developed and better suited for snorkeling.
Can I combine city tourism with diving at TARP?
Absolutely, and that is the park's greatest appeal. You can dive in the morning and be back in Kota Kinabalu for lunch. The park jetty is in the heart of the city at Jesselton Point. This makes TARP ideal for travelers with limited time or those wanting to add a few dives to a Borneo holiday that includes Mount Kinabalu or wildlife tours.
