Mandolin - Sulawesi

Mandolin is one of those sites we always recommend to friends heading to Sulawesi. It’s not just the sheer number of species, though 197 is a solid count. What really gets us about Mandolin is the sheer scale of the staghorn coral formations. They stretch out like underwater forests, creating incredible channels and overhangs, especially when the light hits them just right mid-morning. We’ve drifted through here feeling tiny, watching schools of fusiliers dart amongst the branches, so thick they almost block out the sun. Keep an eye out for the small giant clams tucked into the coral; their vibrant mantles are always a treat. It’s a site that rewards a slow, observant dive, perfect for photographers or anyone who just wants to soak in a really healthy reef system. If you can time your dive for a sunny day with minimal current, you’re in for a real treat.
