Hattivatti - Sulawesi

Long Caye Ridge is one of those spots in Lighthouse Reef where we always feel like we’re seeing something new, even after a dozen dives. It’s a shallow drift, usually, with a current that nudges you gently along a sloping wall, topping out around 19 metres. Our favourite way to dive it is to drop in just south of the main ridge and let the water carry us north. You'll float over brain corals the size of small cars, their convoluted surfaces a mosaic of colour. Look closely in the nooks and crannies – we’ve often spotted Roughhead Triplefins perched on the coral heads, tiny but with so much character. Schools of Schoolmasters hang in the blue, sometimes so thick they form shimmering tunnels. We love finding the Mottled Jawfish here, poking their heads out of sandy patches, often with a clutch of eggs in their mouths. Keep an eye out for turtles munching on the turtlegrass beds near the shallower parts of the ridge. The whole dive has a peaceful, unhurried feel. It’s ideal for photographers or anyone who likes to take their time and really observe the smaller stuff.
