Dive Lembeh Strait and Bunaken in North Sulawesi

Lembeh Island is a small isle located to the north of Sulawesi Island in Indonesia. Between Sulawesi Island and Lembeh Island, runs a narrow strait called the Strait of Lembeh. Scuba diving in this strait you can see some of the most unique and spectacular creatures alive. Lembeh strait is renowned for the best muck diving in the world. 

Bunaken Island, also located north of Sulawesi with crystal clear water and spectacular coral walls offers great blue water diving and some of the best snorkeling I have ever done. Read on if you want to know all about diving from Lembeh strait and Bunaken; dive sites, accommodation, season, liveaboard options and more. I stayed in Bunaken first and went from there to Lembeh.

Bali is the most popular island in Indonesia to visit, it also has some great muck diving check out our complete Bali Diving and Travel Guide or dive the nearby Nusa Penida for big creatures like Mantas and the amazing Oceanic Sunfish. Bali is easy to reach with international flights and explore other amazing islands Indonesia such as Komodo near Flores from.

Dive Lembeh strait

Working as a dive instructor while traveling you hear stories about some spectacular places, the tales of Lembeh placed it high on my dive bucket list. Renowned as one of the best places for Muck diving in the world, the stuff you can see at Lembeh Strait sound to good to be true, it is not, I dived there, the stories are true. Muck diving is a subset of Macro diving, don’t let the name turn you off, you do not dive in sewage, conditions can be great. 

During muck diving you hunt for small, weird and wonderful creatures, the  name originates from the bottom composition, dark sediment often silty, muddy or “mucky” environment. The visibility can be good, just practice good buoyancy not to stir up the bottom! At some of these spots the creatures you find in these environments can be unbelievable, made even more spectacular by the dark, dull backdrop. Muck diving is a fairly new discipline that only started in the 1980’s, the story goes a liveaboard boat was anchored somewhere of the reef for lunch when some divers testing gear discovered unreal creatures on the black volcanic ash. The Lembeh Strait has a reputation as the best muck diving in the world being home to some of the strangest and most rare marine animals in existence. This place is any photographer’s dream with creatures many can not even imagine exist and the black volcanic sand gives no glare when using a flash when taking photos. Arriving at Lembeh it feels more like a river than the ocean, being surrounded by jungle and massive trees, with black sand and volcanic rocks everywhere.I remember descending onto the black sand not being very impressed by rubbish like wine bottles and plastic bags on the dull bottom, but seconds later I was amazed by the life here. Our dive leader was excellent quickly pointing out a seahorse and our first amazing creature of the trip, a flamboyant cuttlefish which I was lucky enough to capture catching a Myid shrimp! From here the action never stopped with hairy frogfish, seahorses, blue ring octopus, mimic octopus, mandarin fish and more draining my camera battery.

I think Indonesia is the country with the best diving on the planet. We have been privileged to travel this amazing part of the world extensively and do an amazing variety of diving from muck diving to swimming with big pelagic creatures. See our Complete Indonesia Dive Guide for all about the best diving around the world’s biggest island country.

There is some rubbish on the bottom, sometimes hosting incredible things!

Season to Dive Lembeh Strait

North Sulawesi has an equatorial climate, so it has  sunny, warm weather all year. There are only 2 seasons – the rainy season from November to February and the dry season from March to October. It usually only rains for a short period of time about an hour or two per day in the rainy season.

Lembeh Strait can be dived all year round, conditions and visibility does vary, but some of the critters are always around and visibility is not such a big concern with macro diving. Liveaboard boats dive here in all seasons. 

Peak season is July and August with the greatest number of critters around, this is also the time when the water temperatures are the lowest at 25-26°C, but the most divers are here and it is a good idea to book ahead. 

Low Season is from January to June with fewer divers and not peak conditions, but still very diveable.

October to December period has the best visibility, while it is the lowest in January and February.

Diving in Bunaken

Bunaken is not far from Lembeh and is well known for a very different kind of diving, blue water, steep walls with big fish and other pelagic species. From Manado I first went to Bunaken Island by public boat.  The island is truly beautiful, tropical jungle surrounded by mangroves running into the ocean. Bunaken Marine Park was one of the first marine protected areas in Indonesia established in the early nineties. Steep walls drop into the deep covered by an amazing diversity of soft and hard corals. The drop offers excellent wall dives, keep an eye on the reef for species such as mantis shrimp and a diversity of nudibranches, look around you in the blue for many turtles, huge Napoleon wrasse and large pelagics; sharks, tunas and schools of barracuda. Bunaken is surrounded by shallow reef with a steep drop to over 30m. Many corners and points make great dive spots to see passing pelagics from, the shallow part of the reef is great for snorkeling or doing your deco stop.

Marine Life around Bunaken Island

Just shy of 400 species of coral can be found in the crystal clear water of the Bunaken National Park, definitely one of the most colorful dives in the world. Over 2000 species of fish frequent the spectacular walls. A few of them you are likely to see are Big Napolean wrasse on moste dives, many turtles there are 5 kinds different kinds in the park, white-tip reef sharks, tuna is often seen, plenty of blue-fin trevally, large bumphead parrotfish, large schools of chevron barracuda, solitary greater barracuda schools of big-eye travelly, giant trevally, large schools of triggerfish, surgeonfish, fusiliers and schooling batfish, eagle rays and sometimes manta rays.

Bunaken Island Snorkeling

From the mangroves a 2m deep fringing reef extends about 50m into the ocean ending in a spectacular drop into the deep. Snorkeling around the island is excellent, the shallow fringing reef allows for shallow snorkeling for anybody starting on the shore. The shallow water, sunlight and plenty of coral species create a beautiful garden for snorkeling with plenty of species of smaller tropical fish, we saw some big bumphead parrot fish in shallow water and a couple of big turtles. The drop-off close to shore allows for great free diving on this amazing reef and diving into the deep on the drop-off I saw plenty of turtles, jacks and massive Napoleon wrasse.
