Lembeh Strait is known as the Muck Diving Capital of the World, a reputation wholly earned every time divers visit the area. The variety of bizarre critters and creatures you encounter here is astounding every dive. Again and again.

At first, Hairball seems like a “boring” plain of black sand, but it’s actually one of Lembeh’s most famous dive sites. The amount of vaeriety between all the critters is simly stunning.

Nudi Falls

Tiny frogfish at Lembeh Strait

If you enjoy macro photography, Nudi Falls is a great way to focus your lens on anything from the titular Nudibranchs to tiny frogfish slowly moving along the sand. There’s a miniwall with an electric clam as well.

Air Perang means “water battle”, named after two villages vying for control of drinking water back in the days. This site is perfect for an exciting night dive. Spot the stargazer peering up into the darkness.
