Diving in the Lembeh Strait

The Lembeh Strait, located in North Sulawesi, is simply one of the most special and exclusive diving destinations in the world.

Known for its amazing marine biodiversity, Lembeh is the perfect place for lovers of “muck diving” or diving in search of macro critters, where you will discover fascinating marine life that can’t be found anywhere else in the world.

This destination is ideal for those looking for something beyond traditional coral reefs. On its black sand bottoms, you will find such strange species as the mimic octopus, the flamboyant cuttlefish, frogfish of all kinds or the tiny pygmy seahorses, which make diving in Lembeh a dream for underwater photographers.

Lembeh attracts mainly experienced divers, as the search for small and well-camouflaged marine inhabitants can be a challenge. However, with the help of expert local guides, every dive is a new adventure filled with critters you’ve never seen before.

Finally, its proximity to Manado and convenient accommodation options at dive resorts make Lembeh a very accessible destination and perfect for a unique experience. 

Don’t miss your chance to explore this little corner of Sulawesi!

How to get to the Lembeh Strait

The Lembeh Strait lies just off the northeastern coast of Sulawesi, opposite the port city of Bitung. To get there, fly into Manado (MDC), the capital of North Sulawesi. There are daily flights from Jakarta, Bali, and Makassar, as well as some connections from Singapore.

From Manado, it’s a scenic 90-minute drive along a nice highway to Bitung. Once there, most dive resorts are located on Lembeh Island itself, just across the strait, so a short boat transfer will take you directly to your accomodation. The entire journey is usually arranged by your resort.

Connections are generally smooth, but since you’ll be heading to a remote diving destination, we recommend leaving a bit of flexibility in your travel schedule. At Karang Travel, we’ll help you organise flights and transfers if you need, so you can arrive relaxed and ready to dive.

How to dive the Lembeh Strait

For the best muck diving experience in Indonesia, staying at a dedicated dive resort in Lembeh is the way to go. Resorts are located right on the beach on either side of the strait, with a house reef just steps from your room—perfect for a relaxed afternoon or night dive. 

Dive sites are just minutes away by boat, allowing for easy access and multiple dives each day. Most dives are done from small speedboats, with two to four scheduled daily dives and the option for night or sunset dives. Unlimited unguided house reef diving is usually included with dive packages.

Diving in Lembeh is all about patience and detail. It’s slow, focused diving, with long bottom times allowed so you can enjoy every minute with rare species like frogfish, ghost pipefish, seahorses, and octopuses. Most resorts are also specialised in underwater photography, offering camera rooms, rinse tanks, and guides who know exactly how to find and frame the most elusive critters.

A few liveaboards include Lembeh in their itineraries, usually combined with Bangka, Bunaken, or other parts of North Sulawesi. These trips are ideal if you’re looking to explore a wider variety of underwater environments during your journey.
