Lembeh strait is one of the most interesting marine habitats that I know, a real macro paradise and a great place to do scuba diving! I first dived here in 1994 but have come back many times and must have done over two hundred dives only here, so I know the place rather well. There are over 60 dive sites around the Lembeh strait, most of them are either sandy areas or small reefs. Don't expect spectacular walls or huge reefs, here you are doing so called muck diving - searching for the rare and the special (for more good places for muck diving look at Secret Bay and Padang Bai in Bali, Dauin in Negros, Cabilao in Bohol situated in the Philippines and Mabul in Borneo). I am a frogfish specialist and the Lembeh strait is just full of them (see video from Lembeh). But it's also a good place to see other shy critters such as the mimic octopus, the flamboyant cuttlefish, harlequin shrimps, wonderpus, skeleton shrimps and many nudibranchs. The fish at this place are also a collection of weirdoes: Ambon scorpionfish (Pteroidichthys amboinensis), stonefish, sea robins, stargazers, devil fish and even the weedy scorpionfish (Rhinopias frondosa). There are also beautiful seahorses (we counted at least 7 different species, pygmy and others), pegasus, ghost pipefish and the endemic Banggai cardinalfish. Special link: fishes of Bitung
Although most divers come here for the muck diving, Lembeh has much more to offer. Specially around Lembeh island there are some small but very beautiful coral reefs and at the northern tip at Batu Kapal the currents attract large pelagics like mackerels and sharks. There are also four beautifully covered wrecks, two of them large and all within limits for recreational diving. This area is not a national marine park unfortunately. Water temperatures can sometimes be a bit cold, in July-August it can be until 26 °C, the other months around 28 °C. The sheltered condition of Lembeh Strait makes for year-around diving.

The main town, Bitung can be reached by car (1 - 1 1/2 hour depending on traffic) from Manado. Bitung is a large, busy harbor full of containerships and fishing boats. In the last few years the town has prospered. In 2007 it was even awarded a price for being one of Indonesia's cleanest and healthest city. Situated on the eastern side of the tip of North-Sulawesi, the Lembeh strait (Selat Lembeh) runs between the Sulawesi mainland and Lembeh island to the east and is 22 km long and 2 km wide. There are some interesting white limestone walls and a few smaller islands or rocks (Batu Sandar, Sarena Kecil, Kai-nah) in the middle of the strait and a lava flow visible around Batu Angus (= burnt rock). Lembeh island is also an interesting place with some wildernes areas where Tarsias monkeys, large monitor lizards, birds and land turtles live.

There are 12 dive resorts on either on the mainland or on Lembeh island (2013). You can also organize day trips from Manado / Bangka. Another possibility is to stay on one of the liveaboards and spend a few days in Lembeh strait.

I noticed, that there are seasonal changes at the dive sites
in Lembeh. On one visit a dive site would be just full with nudibranchs eating
certain types of algae, an other time of the year they had all gone to some
other dive site. At one time ghostpipefishes or seahorses were everywhere, then
we had a hard time just finding one. So it is best to get a dive guide who has
recently dived around here, because he will know about these changes and the
best places to visit. Dive sites on the mainland have dark volcanic sand, those
around Lembeh island all have ligther sand. Click here
for a print version of this list of dive sites.
Police pier (No. 6): This dive site is a real muck
dive! There is a lot of garbage lying around, but among this garbage are real
treasures! Unfortunately this dive site is not so good anymore (2006), too many
ships on the pier. I found two harlequin shrimps (Hymenocera picta) on a Linckia
starfish, under the large columns of the pier there are special waspfishes,
many nudibranchs and there are a lot of Barramundi cods and the Banggai
cardinalfishes (Pterapogon kauderi). They seem to be hiding among the spines
of sea urchins and also joining the anemonefish hiding in anemones. The Banggai
cardinalfish is actually endemic to the Banggai islands and it was probably
introduced to Lembeh strait by dumping some aquarium specimens. Over the years
it has spread from here first to the islands in the strait and now to nearly
all dive sites on the west side of the strait! Since there are a lot of orange
sponges this dive site is a really good place for the orange painted frogfish
(A. pictus). On one of our dives we found a total of seven while diving here.
One of them was a female bloated with eggs with a smaller male guarding her.
Nudi Falls (No. 7): is a small vertical rock wall
and below that a slope with dark grey sand and rubble that ends at about 27m.
On one dive we went deeper and searched in between the sponges for the weedy
scorpionfish (Rhinopias frondosa) but didn't find it. Instead I saw some rare
spindle cowries (Phenacovolva tokioi) and a flamboyant cuttlefish. At the wall
there is a Muricella gorgonian where you find pygmy seahorses (we saw 7 of them)
and there is a crack with two flame file shells hidden. Sometimes there are
strong currents around the deep section on the rubble slope. A year later we
finally found the Rhinopias there
(read how to differ the main
Rhinopias species, photos). On a
dive a year later I finally found out, why this dive site is called Nudi Falls
- there were nudibranchs everywhere and some like Risbecia tryoni were mating
in large numbers.
Jahir (No. 14): A dive site with a large sandy
area and coral blocks. On my last visit this was an excellent place to see hairy
frogfishes. There were three around and to my amazement one was hiding between
a dozen of the longspined diadema sea urchins, one fin actually resting on the
spines! The other two were busily engaged in courtship. The larger female was
bloated with eggs and the smaller male was folllowing her and nudging her all
the time. I observed them for quite a long time hoping they would actually rise
to the surface and she would release her eggs but this didn't happen and a day
later they were still only courting.
Nudi Retreat (No. 17): This dive site is a small
and protected cove. On the top resides a pair of pegasus sea moths and a lot
of different nudibranchs. A few times we started our dive about 50m north on
a beautiful wall covered with soft corals, an other place to dive well worth
it. Apart from a several species of nudibranchs we also saw two Coleman shrimps
which live on poisonous sea urchins - a rare find!
Teluk Kembahu TK (No. 22): The mimic octopus was
first observed here in Lembeh Strait. A dive guide noticed, that an unknown
species of octopus sometimes looked like a flounder or like a mantis shrimp.
Further observation established, that through altering the position of its striped
arms, the octopus could also mimic lionfishes, sea snakes, crocodile snake eels,
stingrays and jellyfish. We found a mimic octopus while it was foraging for
crustaceans and fish by probing with its long arms down holes. When it espied
us, it started to mimic a flounder, pressing its arms together, all in one direction
and undulating to mimic the way a flounder swims. Later it looked like a sea
snake and just before disappearing in its lair like a mantis shrimp. It seems
to mostly imitate either poisonous animals or ones that are not particularly
tasty, so predators don't want to eat it. It is one of the only octopuses that
dares to swim in open water close to the surface - of course mimicking another
poisonous animal, a jellyfish! There is another octopus, the wunderpus that
looks similar but with a more distinguished color pattern.
Lettuce Surpriz U or Kuda Laut (No. 23) lies on a nice bay with a beautiful
view of the volcano - a good place for the lunch break. A lava flow on the northwestern
end of the bay forms a series of crater like depressions filled with lettuce
corals and other hard corals. The dive operators have given this dive site two
names - Lettuce Surpriz U for the lettuce corals where Mandarin fishes (used
to) live and Kuda Laut for the seahorses you find here. You dive on a flat slope
of black sand with patches of corals and sponges. On one dive we encountered
a flamboyant cuttlefish (Metasepia pfefferi) laying eggs. She had chosen an
overturned half of a coconut to hide her eggs. First she blew some water on
the sand under the edge of the coconut to form an opening. Then she stretched
her arms and neatly slid them underneath. She was changing colors and then retreated
having put her eggs inside the shell. We did also did one dive only in the upper
10m and found a pair of filamented ghost pipefishes (Solenostomus paegnius)
and crabs walking around with sea urchins on their back and the coconut octopus.
Hairball Two (No. 24): this site is close by and
is similar to hairball. On the top there are special sea urchins with cardinal
fishes and zebra crabs and large yellow and brown seahorses. These seahorses
are amazingly fast. I tried to make a photo and it would start moving really
fast so I nearly couldn't follow! I also encountered a juvenile batfish, that
looked like a brown leaf (Circular spadefish - Platax orbicularis) and another
with zebra stripes (Hump-headed spadefish - Platax batavianus).
Hair ball (No. 24): at this dive site there is
some of the world's best critter diving, a true muck dive site. A gentle slope
covered with black sand and algae. Since most of the dive is sand you need a
bit of patience, you might dive for a couple minutes and not find anything and
then you get surprised by truely rare animals. There are occasional patch of
sponges - those are the places to look for hidden animals like seahorses, frogfishes
or the Ambon scorpion fish. All these animals are extremely well camouflaged,
the frogfish we found was brown and gray with numerous appendages, the seahorses
brown or black with algea like growth.
Aw Shucks (No. 26):
This dive site is close to the pearl farms in the northern part of Lembeh
strait. I liked this dive site since we encountered several times a lot of beautiful
ghost pipe fish and two yellow double-ended pipefish that look like sticks of
whip coral. On the small reef on top there were two yellow leaffish and a large
Notodoris minor slug, also yellow.
Pantai (or Pante) Parigi (No. 45) lies on Lembeh
island just close to the huge white limestone formations. The name can be translated
with "beach with a well". You dive on light grey sand on a gentle
slope. This turned out to be a good place for the Ambon scorpionfish (Pteroidichthys
amboinensis) and frogfishes (Antennarius striatus and pictus). These animals
were hidden among the algae and some ropes that were lying on the sand. There
are also quite a lot of broccoli soft corals with tiny porcelain crabs and egg
cowrie snails living on them. On one dive there we saw the rare leafy filefish.
From far this filefish looks like a piece of seagrass or weed with its many
appendages. There are some patches of corals in the upper area of the dive site
with nudibranchs (for example sea hares) and sometimes a leaffish or frogfish.
a) Tanduk Rusa wreck (Mawali wreck): lies at 1° 26.778' N and 125° 13.536' E. This Japanese freighter burnt and sank in 1943. Rob Sinke from Divers Lodge Lembeh has found a fused compass and melted bottles. He thinks the reason why so much hard coral grows on the wreck is because all the paint was burnt off. It lies on the port side, large poles sticking out. You either start the dive from the propeller or you dive towards the cargo holds and the bow. It is nicely covered with beautiful hard corals. Depths start at 16m and go to 31m.
I visited this wreck first in 94 and we had to get a local fisherman
to find it, since there was no buoy attached. You can enter the large cargo
holds in front which is very interesting but watch out for your deco time! Don't
go into the machine room, this area is much too unstable! When there is a current,
the wreck is just chock a block with large lionfish, no place to really hold
on to the wreck, because they are everywhere. We also saw shonefishes, jacks,
batfish, cuttlefish, quite a few nudibranchs and mantis shrimps. There used
to be two frogfish sitting on the poles and a school of glasfish always around
them, but our dive guide told us they are gone.
b) Kapal Indah: this is a cargo boat about 45m
long and lies between 17 and 24m deep, upright on its keel. It is mostly covered
with bryozoans, hydroids and sponges and there are a lot of nudibranchs, some
very rare living there and on a large sponge on the top of the deck perched
a giant frogfish, ready to devour the fishes around him. After diving on the
wreck you can finish the dive on the small coral patches further towards the
shore. Close to Kapal indah lies Kapal Baru,
a boat that burned and sank recently and lies between 4 and 14 meters. This
is a nice place for night dives (only for small dive groups), you see a lot
of crabs, nudibranchs and perhaps a ghostpipefish.
c) Bimoli wreck: This is also a Japanese freighter
which sank during the second world war. It lies now close to Bitung in the middle
of the shipping area. You can sometimes hear ships going by, so it can be very
noisy and the visibility is not always very good - also be careful when you
surface! Unfortunately when I wanted to dive the wreck this year (2006) we encountered
people taking the metal from the wreck to sell for scraps. I wasn't able to
dive the wreck, but the police later stopped them from lifting up more material,
but large parts were already destroyed, mostly the upper parts but all the interesting
parts like the propeller, the gun and bull eyes were gone. I will try to have
a look at it next time I am there to see if it is still worth diving here. The
Bimoli is about 100m long and the deepest parts lie on 35m. The Bimoli (real
name not known) was torpedoed either from air or by submarine (the last is what
the locals say) and sank. The ammunition (Bakelite) is still there and I hope
nobody is stupid enough to try to lift that too up to the surface. The Rina's
wreck and Kapal Baru have also been destroyed
by people taking scrap metal from them.
Batu Kapal (No. 28): This dive
site is not so well known, but it actually was one of the highlights of my dive
vacation! Rob Sinke from Divers Lodge Lembeh is one of the persons that knows
this dive site well, so we dived there when currents were strong but not too
fierce. You dive on several large submerged rocks which are jutting up from
a plateau of about 22 to 27m. Everything is covered with yellow tube corals
(Tubastrea) - what a sight it must be during night when they all open - and
hard and soft corals. The amount of fish is just amazing, from small Anthias
and red tooth triggerfishes, bannerfishes to mackerels, Napoleon wrasses and
the occasional shark. The current carries you among the rocks, sometimes you
stop and watch the fish soup, sometimes you drift to another current pocket.
If strong currents or waves make it impossible to dive at the pinnacles you
might still be able to dive at the wall of the largest rock because it is somewhat
more protected there. At 15 meters at the foot of the wall there is a gentle
slope with large boulders. At about 22m it suddenly gets steeper with large
gorgonian fans and we found sharks, Napoleon wrasses and large schools of snappers.
Dante's Wall (No. 29): You start this dive in a
small bay a bit south of Batu Kapal. It is a slope covered with hard corals.
Sandy areas reach like long bands down between. Several times on our dive we
encountered a large group of barracudas and between we saw some rainbow runners,
a group of bumphead parrotfishes which were feeding on the corals and a turtle.
Pulau Putus and Californian dreaming (No. 32 and 33):
Most people come to Lembeh for the rare critters, but some dive sites
like these have beautiful rich coral growth and colorful reef fishes! Specially
look out for the cleaning stations here, apart from the colorful cleaning shrimps
you might find some leaffishes or frogfishes there also.
Angel's window (No. 35): This dive site is a large
rock with two peaks off the north coast of Lembeh Island that rises to just
a few meter below the surface. There is a large swim through at about 25m, and
around them are several gorgonian sea fans (Muricella paraplectana) with pygmy
seahorses (Hippocampus bargibanti) and outside there are other gorgonians with
the yellow Denise seahorse (Hippocampus denise). On the way along the wall we
saw many damselfishes mating and on top of the pinnacle we discovered a huge
stonefish covered with algae like growth. All around were anthias and damselfish,
all the stonefish had to do to get the next meal was to just open its mouth!
Southeast coast of Pulau Lembeh (No. 61 to 67): During
the northwest monsoon (November to April - map
with weather in Indonesia) it's also possible to dive on the eastern side of
Lembeh island. These dive sites are well worth a visit. Just close by is Pulau
Dua (No. 64), a small island with a nice beach where you can eat your
lunch. The dive site here is a large and steeply inclined ridge. There was some
current when we dived there and fish gathered a plenty, schools od fusiliers
and butterflyfishes as well as a occasional mackerel and Napoleon wrasse and
a white tipped reef shark was cruising back and forth underneath. On the several
dive we did there we always found two or three giant frogfishes perching on
the huge brown sponges that grow a plenty on the slope. On the rocky part on
the top live octopuses and scorpionfishes and in the crevices morey eels and
dragonets.
On the coast the coral is also very nice, specially at Jiko
I, II and III (No. 63). You dive on a steep slope covered with
mostly hard corals and many small animals such as orang utan crabs or nudibranchs
to be found. Check out the outcrop of corals in Jiko I (at 25 to 29m), it is
teeming with live, small reef fishes, angelfishes, butterflyfishes and groupers.
There is another dive site further north at Batu
Bunyan (hidden rock No. 67) there are sharks, eagle rays, bumphead
parrotfishes and large pelagic and the boat crew also saw a dugon during one
of our dives (but we didn't see it underwater...).
Of course night dives are also specially interesting in Lembeh.
As soon as night falls nocturnal critters like crabs, worms, feather stars,
cuttle fish and eels appear. Some animals like scorpionfishes are much more
active at night, but we also found some ghost pipe fishes and juvenile batfishes
on night dives. Most dive sites in Lembeh strait are also good for night dives.
I believe that a combination of reef and sand is best to encounter a large range
of nocturnal animals. Dive sites like Nudi Falls or Nudi Retreat are also just
beautiful, because the tube corals on the walls open their tentacles and the
wall becomes a yellow meadow!
Police pier (No. 6): During night you dive on the
sandy part and don't go under the pier. This dive site is full of surprises.
Not only did we find some of the frogfishes and humpback scorpion fishes that
can also be seen during day time, but our dive guide also discovered the rare
Bobbit worm. This worm is nocturnal and waits in its lair until a fish or some
other animal swims over his head that sticks out of the sand. Then it extends
its pincers and strikes, grabs the unfortunate fish and drags it down into its
lair. Apart from the Bobbit worm there are of course also a lot of nudibranchs,
crabs, shrimps to be seen.
Air Prang (No. 13): South of Air
Prang is a small beach with a flat sandy area in front which I found specially
good for night dives. Several bobtail squids, huge red and white nudibranchs
that bury in the sand during the day and emerge at night, small nocturnal scorpionfishes
and of course the usual - octopuses, slugs, frogfishes, shrimps and crabs.
Nudi Retreat (No. 17): This dive site is a small
and protected cove. We also did a night dive there and found a ghost pipefish
in one of the sponges. The highlight was a juvenile batfish with an orange fringe
that looked just like a flatworm! Amazing! We also encountered a sea snake and
a huge Pleurobranchus snail.
Divers Lodge Lembeh house reef (No. 59 and 60): Start
the night dive around half past five and first go to observe the Mandarin fishes
(Synchiropus splendidus) while they are mating. They live in rubble, mostly
broken staghorn corals and during the day they are very well hidden. But around
5 o'clock (dusk) they start to forage among the corals and it is easy to find
them. We went several evenings in a row and found, that once it gets dark they
start their courtship dance. The male (larger) displays his dorsal fins to attract
the female. Soon they rise together from their lair, side by side, and head
for open water to release spawn and eggs. After this spectacular experience
you can continue to the nocturnal seahorses (probably Hippocampus mohnikei)
which live in the staghorn corals close by. These seahorses are very agile and
climb around in the branches to search for food. There is plenty more to see
- featherstar crabs, nudibranchs, moray eels and with luck a sleepy ghost pipefish.
My recommendation: A great DVD with coverage of the rare animals living in the Lembeh strait by Shark Bay Films "The Critter Trilogy" (John Boyle). Filmed entirely in Indonesia's Lembeh Strait in open water. Great coverage of frogfishes feeding and much more! Sold by www.electricsky.com.
