Why dive here
With 238+ marine species recorded in the area - including blacktip reef sharks, giant moray eels, pygmy seahorses, seahorses and sperm whales - Great Wall offers some of Sulawesi's richest wall diving. Water ranges 29-31°C, warmest June, October, November.
The Great Wall in Sulawesi is exactly what it sounds like, a sheer drop into the deep. We’ve found the wall here is covered in soft corals, particularly vibrant gorgonians and a few resident frogfish if you have a keen eye. It’s an easy drift, suitable for most divers looking for a relaxing wall dive with good chances of spotting a few larger pelagics out in the blue.
