CharacterReef dive

StandoutExceptional marine biodiversity

Katrin reef in Sulawesi offers a relaxed dive, good for getting your buoyancy dialed in. We’ve found a healthy amount of branching staghorn coral here, a real focus for the site, providing plenty of nooks for small stuff. Keep an eye out for the snowball chama, a neat little clam, and we often spot dwarf morays tucked away. Pink anemonefish are a regular sight, busy in their anemones. It's a nice spot for a second dive or if you're looking for something calm.
