Description of dive sites.....

Koh Mak is very close to national marine park Koh Rang, the divesites there offer great coralreefs and colourful dives. We head out to the national park most days. On other days we dive the local sites around Koh Mak, good coral reef and interesting rock dives. During dry season the visibility is good to very good, the sea is calm and flat. The dives are quite shallow and easy, perfect for relaxed dives and enjoying the beautiful reefs.

Once or twice a week we head to the Koh Chang wreck combined with other sites around the HTMS Chang wreck. The wreck offers spectacular diving so at times we stay there for 2 dives. On this day we make 3 dives a day. The schedule is flexible, depending on weather and customer requests.

Quite often we make a special trip to Koh Kood where we make 2 dives, have lunch in a nice local restaurant with seaview and we take you up the river to visit the beautiful Klong Chao waterfall. This is a great day out diving and snorkeling combined with visiting Koh Kood Island.

Koh Mak dive sites

Koh Phe

10 - 18 m, 

Lovely divesite with nice variety of coral reef and rock formations. Quite a lot of fish around, mostly small coralfish. 

Koh Rayang

6 -16 m

Easy relaxed dive with good coral reef. Great snorkeling site as well.

Koh Rang National Park sites

Hin Ga Daeng (Koh Rang pinnacle)

  • Depth: average 15 m / max. 30 m.

This spectacular pinnacle is the deepest dive around Koh Rang, a great multilevel site. The rock itself has a very special structure, looks like an underwater cathedral. There are plenty of fish around it, not so much coral though. Things to see are big barracuda, porcupine, groupers, triggerfish, turtle, nudibranches, sweet lips, and schools of batfish. The currents here can be quite strong and unpredictable, but it is certainly worth the effort! Great site for photography.

Koh Tien West

  • Depth: average 10 m, max. 16 m.

Sadly enough on one side of the island the coral is mostly destroyed by anchoring fishing boats and dynamite fishing, but it is a good spot to see how the reef is recovering. On the southside of the island there is the biggest formation of staghorn coral you re likely to see, forming a stunning view and protection to an abundance of fish. Also great snorkeling site.

Hin Kuak Ma (or three finger reef)

  • Depth: average 10 m, max. 16 m.

This is one of the greatest dives here. The south side is a rock wall, good to spot eels, nudibranches, stone fish etc. The backside of the rock is a slope, covered in coral, and with an abundance of fish. Sometimes we spot a bamboo shark or turtle, every dive we see blue spotted stingrays, moray eels, blue ringed angelfish, parrotfish. Good snorkeling if there is no current.

Koh Yak and Koh Laun

  • Depth: average 8 m, max. 1 2m.

These small islands are ringed with a very beautiful coral reef with a rich abundance of different coral fishes. Both islands are small enough to dive around; because of the shallow depths we have plenty of dive time. Many divers' favourite…


Koh Chang dive sites 

HTMS Chang Ship wreck

On the 22nd of November 2012 the HTMS Chang has been sunk. The wreck quickly turned into a great artificial reef thriving with marine life. It is truly a spectacular wreck dive, the bottom is on 30m, the topdeck on 21m, captain's cabin and mast on 12 meter and reaches close to the surface. The ship is 100m long, making it the biggest shipwreck in Thailand.

Many fish have taken refuge at the Chang, batfish, filefish, scorpionfish, barracuda, giant groupers, squid and octopus,  shrimpfish,... interesting diversity of marine life. The HTMS Chang is lying close to Koh Chang, so it is perfect to combine with either Hin Luk Bath or Hin Raab.

Hin Luk Bath

  • Depth: average 11m / max. 25 m.

This is one of the prime dive sites around Koh Chang. Hin Luk Bath is a pinnacle that offers refuge to plenty of shoaling fish. There are moray eels, stingrays, parrotfish, snappers, fusiliers, big groupers, butterfly fish, banner fish, barracuda, angelfish, and many more. On the way to the dive site we sometimes see dolphins. The pinnacle is surrounded by huge uw boulders that offer some great swim throughs. The deepest point is 25 metres, however, most of the dive we spend from 5 to 16m. This dive site has an abundance of Christmas tree worms, which makes it very colourful. Great for night diving.

Hin Raab South (locals call it Hin Laab)

  • Depth: average 11 / max. 16 m.

This is a rocky site with good variety of coral around it. There are actually 3 dive sites in this area: one is a dive around the rock, a good place to spot turtle, batfish, stonefish, porcupine fish, stingrays, moray eels, often we see big barracuda. We also had quite a few whale shark spottings here. There is an abundance of soft coral. The second one off to the north is a bit deeper and richer in coral and has a lovely small canyon, called secret reef. Here we often see rays, morays, angelfish, groupers, triggerfish, anemone fish, parrotfish. Once in a while we spot a turtle. The third one is the T11 small shipwreck...

T11 Shipwreck

This smaller wreck was sunk for diving in 2013 and is very close to Hin Raab. This gunship is about 30m long, maximum depth at 16 meters. It was sunk in a vertical position but has been used as target practise by the navy so is now in bits and pieces. We often dive this site in combination with Hin Raab.

Hin Tai Nam (Blueberry Hill)

  • Depth: max. 16 m.

This site is located close to Hin Raab, a bare rock full of fish. Only the southside has coral. Great place for spotting nudibranches, batfish, stingray, eels, groupers.

Hin Rua Tek (Banana Rock)

  • Depth: average 10m, max. 16 m.

A rocky dive site, with nice crevices to search for shrimp, lobster, nudibranch, et cetera. There are big table corals, gorgonian fans, soft corals, sponges and more. No abundance of coral, but a dive most people love because of the general surroundings.

Hin Saam Sao

  • Depth: average 11m / max 16 m.

Towards the northwest of Koh Chang, this dive site has some nice corals, rich fish life, but sometimes has poor visibility because of its closeness to land. One side of the reef was destroyed by dynamite, it is recovering though. Max. depth 16m.
