Ring of fire
Why dive here
With 238+ marine species recorded in the area - including blacktip reef sharks, giant moray eels, pygmy seahorses, seahorses and sperm whales - Ring of fire offers some of Sulawesi's richest reef diving. Water ranges 29-31°C, warmest June, October, November.
The Ring of Fire site in Sulawesi delivers a solid wall dive, but with a twist. Instead of just a sheer drop, we get a gradual slope towards the end, which really diversifies the scenery. Down to 13 metres, it’s a pretty relaxed depth, making it good for extending bottom time to really scrutinise the wall. We’ve found a nice collection of nudibranchs here, along with various shrimp and crabs tucked into the crevices. Look out for the purple goby, it’s a striking little fish. Visibility averages around 20 metres, so there’s usually a good chance of spotting a blacktip reef shark or an eagle ray passing through the blue. It’s a good choice for divers who enjoy taking their time over macro subjects but still appreciate a chance at something bigger.
