Monkey Reef, Tulamben: Macro Diving on a Coral Slope

Diving Monkey Reef takes you along a gently sloping coral reef, distinguished by its structure of coral growing on scattered rocks and wide expanses of sand between them. Unlike some of Tulamben's other sites, this is not a sheer wall, but a gradual descent that allows for thorough exploration of individual sections at a relaxed pace. You'll typically begin your dive above the reef crest, working your way down the slope, letting the changing topography guide your focus between the wider reef view and the intricate details found closer to the substrate.

The maximum depth attainable at Monkey Reef is 22 metres, making it accessible for extended bottom times to observe the smaller inhabitants of the reef. The dive profile is straightforward, following the natural contours of the slope. This configuration allows you to move slowly, scanning the corals and sand for camouflaged or cryptic species, which is the primary draw of the site. Your buoyancy control here is key, not just for safety over the fragile corals but for positioning yourself to get a good look at the macro subjects.

While the site benefits from occasional currents, they are generally light to moderate, often allowing for drift diving along the slope once you've located a suitable entry point. These currents, when present, also contribute to the active fish life. You'll encounter schooling fish in the water column and larger predators patrolling the fringes of the reef. However, the prevailing conditions lean towards a calmer environment, ideal for unhurried observation and photography without being constantly pulled away from a subject.

Monkey Reef is particularly known for its macro opportunities, offering a habitat for creatures that thrive in this mixed coral and sand environment. Keep an eye out for frogfish, often perfectly camouflaged against the coral or sponges. Leaf scorpionfish (Taenianotus triacanthus) are also regular features, swaying gently with the water's movement, mimicking dead leaves. The sandy patches between coral growth are also productive for spotting various shrimp species and other invertebrates that burrow or blend into the substrate.

Beyond the macro life, you can expect to see green turtles (Chelonia mydas) or hawksbill turtles (Eretmochelys imbricata) cruising over the reef. Moray eels (Muraenidae family) are common, often peering from their crevices within the coral structure. Schooling bannerfish (Heniochus acuminatus) and various grouper species (Serranidae family) add to the ambient activity. Triggerfish (Balistidae family) are frequently encountered, going about their territorial routines, and the colourful Oriental sweetlips (Plectorhinchus vittatus) are often seen in small groups under ledges.
