About this spot
The Lembeh Strait between Sulawesi and Lembeh Island is the world capital of muck diving. The black volcanic sand and rubble bottoms are home to extraordinary critters: mimic and blue-ringed octopus, ornate ghost pipefish, hairy frogfish, pygmy seahorses, mandarinfish, rhinopias scorpionfish, and dozens of nudibranch species. Each dive is a treasure hunt — the divemasters' eyes are legendary. Visibility is moderate (10-15m), but who needs distance when the action is on a fingernail-sized seahorse.
