Diving in Thailand: The Top 7 Dive Sites to Explore

Apart from picturesque stretches of tropical beaches, streets lined with food stalls, gilded temples, and world-renowned Thai hospitality, Thailand is also home to some of the most sought-after dive spots in the world.

We delve beneath the surface to discover the best scuba diving sites in Thailand, whether you are a well-seasoned, advanced diver, or just beginning to dip your toe into the exciting world of diving in the deep blue.


Where to Find the Best Scuba Diving in Thailand

Thailand is strewn with balmy, palm-lined islands, and numerous world-renowned dive sites. How do you choose which ones to explore? You either find yourself lucky in one of these top dive locations or keep this list handy when planning an upcoming diving holiday.


1. Hin Daeng (Mu Koh Lanta National Park)

Also referred to as ‘Red Rock’, Hin Daeng clings to the edges of the Mu Koh Lanta National Park, a marine park spanning over several islands. Sharing the spotlight with Hin Muang, Hin Daeng is one of the most famous dive sites in all of Thailand.

Hidden below the surface, an eruption of colour emanates from the red and purple corals below. This deep rocky pinnacle in the southern Andaman Sea is the perfect place to encounter an array of reef fish, rainbow runners, barracudas, trevallies and scorpionfish.

If you are an intermediate to advanced diver, and can endure the sometimes choppy waters and challenging currents, then this dive will afford you the chance to swim alongside reef sharks, manta rays and whale sharks. Navigated by speedboat from Phi Phi or Koh Lanta, this is definitely one for the bucket list.

2. Hin Muang (Mu Koh Lanta National Park)

Otherwise known as ‘Purple rock’, this prime diving spot and Thailand’s tallest wall dive, is littered with purple-hued corals, anemones and macro marine life. This rocky underwater ridge connects to Hin Daeng a few hundred metres deep below the surface of the Andaman Sea.

Surrounded by open water, intermediate to advanced divers are better equipped to handle the weather-dependant conditions and strong currents of this dive site. Traverse up to 30 metres below the surface and you’re likely to find schools of barracudas, tuna and jack fish alongside whale sharks and feeding manta rays below.

As part of southern Thailand’s Krabi province, Hin Muang can be accessed by liveaboard or a short, sometimes choppy ride by speedboat from Koh Lanta.

Other dive sites near Mu Koh Lanta National Park: Koh Haa Yai


3. Chumphon Pinnacle (Koh Tao)

The most notable dive locale in Koh Tao (or ‘Turtle Island’), Chumphon Pinnacle, is better suited to the advanced diver. The pink anemone-encrusted pinnacles in the Gulf of Thailand are home to an array of marine life, which share the 45-metre depths with an equal abundance of eager scuba divers.

Koh Tao is renowned for spectacular coral reefs and varied marine life, as is Chumphon Pinnacle, from chevron barracudas, trevallies, big eye jacks, to scorpion fish, giant grouper and batfish lying in wait near the bottom. Keep an eye out as the site is occasionally visited by whale sharks too!

Other dive sites near Koh Tao: Sail Rock, HTMS Sattakut shipwreck, Shark Island, Japanese Garden and Koh Nang Yuan


4. HTMS Chang (Koh Chang)

Located in the Gulf of Thailand, Koh Chang (or ‘Elephant Island’) is the country’s second largest island and home to its longest shipwreck. On-land, the Koh Chang National Park is a thicket of rain forest, while the surrounding waters in the National Marine Park are rich with corals and marine life.

A once warcraft, HTMS Chang dates back to the Second World War, but now forms part of an artificial reef that spans over some hundred metres of the seabed. Accessible by all experience levels, this recreational dive site can be better navigated by advanced divers, who can explore the barnacle-laden ship nestled 30 metres deep.

A leisurely boat trip from Koh Chang sees you swim alongside barracudas, batfish, scorpionfish, squid, shrimpfish and the occasional octopus.

Other dive sites near Koh Chang: Hin Luk Bat (3km southwest of Koh Chang), Koh Rang


5. Shark Point (Phuket)

Referred to as the ‘Pearl of the South’, Phuket is host to one of the most well-known dive spots in Thailand. Aptly named after the abundance of leopard sharks that inhabit its waters, Shark Point is the epitome of Phuket diving.

Located within a marine sanctuary, the seemingly small, rocky outcrop in the Andaman Sea reveals a vibrant reef below. Shark Point is most ideal for divers who have open water experience.

A reef clustered with sea fans and plush corals in pink and purple, the main of three dive sites is littered with tropical fish, from trevallies and jack fish to scorpion fish, groupers, cuttlefish, moray eels and squid. The star of the show, leopard sharks are accompanied by reef sharks, and on occasion, whale sharks.

Regular day visits from Phuket are navigated by boat, and exploring all of this dive site may take several visits.

Other dive sites near Phuket: Anemone Reef, Koh Racha Yai, King Cruiser Wreck


6. Richelieu Rock (Surin)

An archipelago in the Andaman Sea, the Surin Islands dive sites are some of the best in Thailand and form the Mu Koh Surin National Park. Most notably, iconic Richelieu Rock is famed for its position in deep, open water, which attract a myriad of marine life to the plankton-rich site.

Regarded as the best place in Thailand to spot the often elusive whale shark, Richelieu Rock, is also the perfect place to dive with other pelagics too. While submerged during high tide, the rocky pinnacle regularly pops above the water’s surface to reveal just a glimpse of the horseshoe-shaped site.

Due to the depth and strong currents, only open water students and advanced divers can access Richelieu Rock and meet the whale sharks, manta rays, barracudas, ghost pipefishes, groupers, moray eels, harlequin shrimp and other creatures that call the area home.

Although there are no islands closely located to the site, it can be easily accessed by way of liveaboard or a day trip by boat from Surin or Khao Lak.

Other dive sites near the Surin Islands: Hin Rap, Koh Chi


7. Elephant Head Rock (Similan Islands)

Set near to the eighth of nine Similan Islands, in an open stretch of the Andaman Sea, this well-visited dive spot is prone to strong currents and a seasonal monsoon-swept sea. Part of the greater Mu Koh Similan National Park, these granite islands are spectacular.

The contours of this uber-popular reef are decorated with hard and soft corals around arches, caverns and swim-throughs. Advanced open water divers can negotiate the challenging currents to discover the local pelagic inhabitants, including barracudas, trevallies, tuna, leopard sharks, manta rays and more.

A little closer to the corals hide groupers, moray eels, sweetlips, mantis shrimp and hawksbill turtles. Best accessed by liveaboard or boat, the journey to Elephant Head Rock is typically made from Khao Lak or Tap Lamu Pier.

Other dive sites near the Similan Islands: Christmas Point, Boulder City, Shark Fin Reef

Top Tips for Diving in Thailand

Thanks to the perennially warm water, diving in Thailand is a year-round attraction. With that said, many top dive sites are located in open water, and exposed to the elements, making them challenging at times.

A few tips for diving in Thailand:

  • Know your limits and try not to dive beyond them
  • A PADI Discover Scuba Diving course teaches you the basics of diving and prepares you for exploring shallow waters around Thailand
  • A PADI Open Water Diver course is recommended for exposed, open water dive sites and can be completed over three days while in Thailand
  • Use the PADI dive shop locator to find certified centres at locations around Thailand
  • Average water temperatures range between 26℃ and 30℃, so you can get away with a rash vest
  • To preserve the vibrant underwater landscape, avoid stepping on the reefs or touching the corals
  • Although they are used to seeing divers, marine animals can be shy, so approach them respectfully and try not to scare them off by making lots of bubbles with your equipment
