Highlights of the Lembeh Strait

Bianca Point

Mating Mandarinfish at Bianca Point, Lembeh Strait

At around 16:30 we take you close by to Bianca Point, and then it’s just a matter of waiting until the Mandarin Fish emerge from the corals to display bright colors during their mating ritual.


Flamboyant cuttlefish at Lembeh Strait

As you slowly progress down Rojos, the bottom changes from gentle sand slopes to scraggly rocks that are home to anything from waspfish to the wonderful Flamboyant Cuttlefish.

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. Some frogfish are so tiny you need a magnifying glass to properly enjoy them.

Air Perang

Stargazer at Lembeh Strait

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