Deep Reef — Pemuteran Bay Dive Site

Overview

Deep Reef was discovered in 1996 and has been one of Pemuteran Bay’s signature advanced dives ever since. The site is a submerged plateau whose steep sides rise from 38 metres to a top at 12 metres, dressed in table corals, giant leather corals, and big plate sponges. The depth and the colder, current-touched water keep the reef in unusually good health, and the structure attracts pelagic visitors that don’t spend much time in the shallower bay sites. It’s a five to ten minute boat ride from our Pemuteran beachfront bases, so it can be combined easily with a shallower second dive.

Marine life & what to expect

The headline feature is the table corals on the plateau — some of the largest in the bay — and the giant leather corals that fold across the steep sides. Look for the red “flaming scallops” tucked under overhangs (their cilia create the flickering effect that gives them the name). Eagle rays cruise the deeper edge in the colder months, and schools of fusiliers and jacks pass through reliably. Common sightings include:

• Eagle rays in deeper water
• Schools of fusiliers and jacks
• Table corals and giant leather corals
• Plate and barrel sponges
• Red “flaming scallops” under overhangs
• Nudibranchs and macro subjects on the slopes
• Sweetlips and snapper on the plateau
• Occasional reef sharks on the deep edge

Dive profile

Best for

Advanced Open Water divers and SSI Deep Diving specialty students. The depth profile rewards good gas management and a deliberate ascent — you spend time on the plateau between roughly 12 and 18 metres after the deeper portion of the dive, which extends bottom time and gives you a relaxed wide-angle window for photography. Wide-angle is the right call here: the table corals, the silhouette of the plateau against blue water, and the occasional eagle ray pass make for compositions that simply aren’t available on the shallower bay sites.

When to dive it

Year-round, with cooler months (June–September) offering the best chance of eagle rays and schooling pelagics. Surface conditions in Pemuteran Bay are sheltered most of the year, but visibility on Deep Reef can vary more than at the shallower sites — we plan the dive to the conditions on the day. We typically run Deep Reef as the first dive of the day so nitrogen loading is lowest, then a shallower second dive at Bio-Wreck or Close Encounters afterwards. Our 1:4 guide-to-diver ratio applies, with extra attention to depth and time signals on this site.
