Lembeh Island sits to the east of mainland North Sulawesi from which it is separated by a long, narrow stretch of water known as the Lembeh Strait.
Lembeh is all about critters and some of the most iconic species of the Strait include hairy frogfish, mimic, coconut and wunderpus octopus, pygmy seahorses, bobbit worms, stargazers, harlequin, tiger and emperor shrimps, ghost pipefish, a plethora of nudibranch species, mandarinfish and the endemic Banggai cardinalfish. Be sure to make a night dive to see the many nocturnal species too
The nearest airport is Sam Ratulangi International Airport in Manado (MDC), which receives flights from Singapore as well as Bali, Jakarta and other cities in Indonesia.
The port of Bitung is around a one and a half hour car drive and from there you will travel onwards either by car or by boat depending on which side of the Strait you are staying. Diving is mainly resort based and most resorts offer airport pickups.
