Dive sites

Popular dive spots and more… The BB Divers’ boats typically head out to local sites around Koh Chang, featuring the popular HTMS Chang wreck, or to the great coral sites in Koh Rang National Park. The dive site selection depends on bookings, weather conditions, currents, and visibility. Both divers and snorkelers can join the same boat, as most coral sites are great for both activities.

HTMS Chang Shipwreck

Koh Chang dive sites

On 22 November 2012, the HTMS Chang was intentionally sunk. The wreck rapidly became the most popular dive site of Koh Chang, suited for open water divers to experienced wreck divers and underwater photographers’ favorite. It now is an impressive artificial reef teeming with marine life. The wreck offers a spectacular diving experience, with its bottom resting at 30 meters, the top deck at 20 meters, the captain’s cabin and mast at 12 meters, and reaching close to the surface at around 5 meters. Spanning 100 meters in length, it stands as Thailand’s largest shipwreck.

Numerous species of fish have found sanctuary at the Chang, including batfish, filefish, scorpionfish, barracuda, giant groupers, squid, octopus, shrimpfish, and more. Regular visits from whale sharks delight both divers and snorkelers, adding to the site’s diverse marine ecosystem. Situated near Koh Chang, approximately a half-hour boat ride away, the HTMS Chang pairs perfectly with either Hin Luk Bath or Hin Raab dive sites.

Hin Luk Bath

Koh Chang dive sites

One of the premier dive sites around Koh Chang, Hin Luk Bath boasts a pinnacle that attracts an abundance of shoaling fish. Divers may encounter moray eels, stingrays, parrotfish, snappers, fusiliers, large groupers, butterfly fish, banner fish, barracuda, angelfish, and more. Surrounding the pinnacle are massive underwater boulders, offering thrilling swimthroughs. While the deepest point reaches 25 meters, most of the dive occurs between 5 and 16 meters. This site is renowned for its colorful array of Christmas tree worms, enhancing the underwater landscape. Additionally, it is an ideal spot for night diving.

  • Location: Approximately 3 km southwest of Koh Chang
  • Depth: Average of 12m / Maximum of 25m
  • Visibility: Ranges from 3 to 20m; excellent for snorkelling as well

Hin Raab South (locals call it Hin Laab)

Koh Chang dive sites

This rocky site boasts a diverse array of coral. Within this area, there are actually three distinct dive sites. The first involves diving around the rock, offering excellent opportunities to spot turtles, batfish, stonefish, porcupine fish, stingrays, moray eels, and occasionally, large barracuda. We’ve also had several sightings of whale sharks here. Soft coral abounds in this location. The second site, situated to the north, is slightly deeper and features richer coral formations, including a charming small canyon known as “Secret Reef.” Here, encounters with rays, morays, angelfish, groupers, triggerfish, anemone fish, and parrotfish are common, with occasional turtle sightings. The third site is the T11 small shipwreck…

  • Location: 5 km south of Koh Chang
  • Depth: average 11 / max. 16
  • Visibility: varies from 3 to 20m, often very clear water and great for snorkelling.

T11 Shipwreck

Koh Chang dive sites

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 horizontal position but has been used as target practice by the navy so is now in bits and pieces. We often dive this site in combination with Hin Raab, it is still nice to see the T 11 even if tattered, the dive towards the reef afterwards makes the site quite interesting.

Hin Tai Nam (Blueberry Hill)

Koh Chang dive sites

This site is located close to Hin Raab, a bare rock full of fish, on the southside there is a nice coral garden. For divers it is a great place for spotting nudibranchs, batfish, stingray, eels, groupers… less interesting for snorkelers.

  • Location: 5 km south of Koh Chang
  • Depth: max. 16m
  • Visibility: 3 to 20m

Hin Rua Tek (Banana Rock)

Koh Chang dive sites

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. We do not dive this site often since the visibility is less good than other sites around there, but on a clear day it is a brilliant site to explore.

  • Location: 3 km south of Koh Chang
  • Depth: average 10m, max. 16m
  • Visibility: from 2 to 15m, OK for snorkelling

Hin Saam Sao

  • Depth: average 11m / max 16m
  • Visibility: from 2 to 10m.

Hin Ga Daeng (Koh Rang pinnacle)

Koh Rang National Park sites

This spectacular pinnacle is the deepest dive around Koh Rang, a great multilevel site. The rock itself has a very special structure, it looks like an underwater cathedral. There are plenty of fish around it, not so much coral. Things to see are big barracuda, porcupine, groupers, triggerfish, turtle, nudibranchs, 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.

  • Location: 1 km northwest of Koh Rang
  • Depth: average 15m / max. 30m
  • Visibility: 5 to 30m

Koh Thien West

Koh Rang National Park sites

This island has recovered nicely after a lot of its coral was destroyed many years ago. It is actually nice to see how the coral reef can recover once it catches on again and comes back better then before.  On the southside of the island there is the biggest formation of stag horn coral you’re likely to see, forming a stunning view and protection to an abundance of fish. A great snorkeling site.

  • Location: just northwest of Koh Rang
  • Depth: average 10m, max. 16

Hin Kuak Ma (or three finger reef)

Koh Rang National Park sites

This is one of the greatest dives in Koh Rang national park. The south side is a rock wall, good to spot eels, nudibranchs, 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.

  • Location: about 1 km northeast of Koh Rang
  • Depth: average 10m, max. 16m

Koh Yak and Koh Laun

Koh Rang National Park sites

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’ favorite…

  • Location: about 1 km northeast of Koh Rang, in the south
  • Depth: average 8 m, max. 12m
  • Visibility: 5 to 20m

Koh Tong Lang and Koh Kra

  • Location: about 1.5 km northeast of Koh Rang, north
  • Depth: average 7m, max. 12

Koh Wai

This lovely paradise island south of Koh Chang is great for a half day trip or overnight stay, beautiful snorkeling, although for diving the reef is quite shallow. Some diving is done on the pinnacles close to Koh Wai, and also on the rocky side of the island. It is a good spot for trainings dives or protected diving when the weather turns bad in rainy season. It offers nice protected dives for discover diving.

Thonburi wreck

This is also called the Koh Chang wreck and was sunk in a fight over Koh Chang between the Thai and the French navy. It is mentioned in many dive guides, but it is in silt water, creating zero visibility most of the time. We just mention it here because it is in some dive sites books, but not fit to dive.

Koh Phe

Diving at Koh Mak area

Koh Phe is a lovely small island with a ring of coral around, max depth about 15 meters. It offers healthy coral reef and a nice variety of fish life and critters.
