Overview

Thailand is one of the most frequently discussed Southeast Asian dive destinations in the Wetpixel archive, appearing across liveaboard trip reports, video showcases, conservation articles, and community discussions. The country’s diving is split between two distinct bodies of water: the Andaman Sea on the west coast, home to the premier sites favored by underwater photographers, and the Gulf of Thailand on the east coast, known primarily as a diver training hub.

The Andaman Sea sites — particularly the Similan Islands, Richelieu Rock, and the Surin Islands — are consistently ranked among the world’s best dive sites by Wetpixel community members. In a 62-reply “Top Ten Dive Sites” thread, multiple members listed Richelieu Rock, Similan Islands sites (Tachai Pinnacle, East of Eden, Elephant Rock), Hin Muang/Hin Daeng, and Koh Bon among their all-time favorites (^[1] — forum). One member described Richelieu Rock as their “number 1” site “when the star attraction is around,” referring to whale sharks, while another listed a Koh Bon night dive alongside it (^[2] — forum). Alex Mustard ranked East of Eden as his eleventh-best dive site worldwide (^[3] — forum). Another member listed Richelieu Rock, Elephant Rock, and Hin Muang among their top ten, though noting that Hin Muang “unfortunately got destroyed in 2007” (^[4] — forum).

Thailand also certifies more PADI divers and instructors than any other country in the world, as noted in Drew Wong’s 2007 ADEX report (^[5]).

Dive Sites

Andaman Sea — Similan Islands

The Similan Islands are a chain of nine granite islands in the Andaman Sea, approximately 65 km off the coast of Phang Nga province. Accessed primarily by liveaboard from Khao Lak or Phuket, the islands offer dramatic underwater topography with large granite boulders, soft coral-covered walls, and diverse reef fish life.

Key sites documented in the Wetpixel archive include:

• East of Eden — One of the most popular Similan sites, known for healthy hard coral formations. Nick Hope shot video here on January 4, 2005, just nine days after the tsunami, documenting hard corals in “great condition along with other marine life including reef fish, octopus, stingray and a green turtle” — providing evidence to counter inaccurate reports of total reef devastation (^[6] — forum). Alex Mustard ranked it eleventh on his personal list of the world’s best dive sites, noting “That said, this week I have been diving in a mucky lagoon in France (1-4m viz) and have been loving it” (^[7] — forum).

• Tachai Pinnacle — A submerged pinnacle near Koh Tachai, listed among the world’s top ten dive sites by forum members for its large schools of fish and pelagic encounters (^[8] — forum).

• Elephant Head (Elephant Rock) — A dramatic granite rock formation, one of the signature Similan dive sites. Multiple community members listed it among their favorites (^[9] — forum).

Forum member “caveman” described the Similans in December 2004 as strong on wide-angle subjects — sea fans, dramatic topography — but noted limited macro opportunities compared to Indonesian sites like Lembeh (^[10] — forum). Alex Mustard commented on the “fantastic” colors in the resulting wide-angle images (^[11] — forum).

Andaman Sea — Richelieu Rock

Richelieu Rock is a submerged pinnacle near the Surin Islands, widely regarded as Thailand’s premier dive site for underwater photography. Jason Heller described it as “a pinnacle in about 120 feet of water, which at high tide is exposed by about 10 feet, and during low tide is totally submerged” (^[12]).

The site is famous for whale shark encounters and dense schools of fish. Forum member Freelio described diving there in November 2022: “Most of the clips are from Richelieu Rock… I was amazed at how great the diving was.” Other members responded that “the fish life is mind blowing,” and Freelio noted: “I wouldn’t have thought Thailand would have made it into my top 10 dive sites but it did.” He took a liveaboard “out of Kao Lak” and noted that liveaboards “normally did 2 dives at Richelieu Rock where most of the action was, first dive not many people around but second dive we were in the water with all of the day boats.” He later disclosed his equipment as “a Sony A1 with a 28-60mm behind a WWL-1b” aboard the MV Andaman liveaboard (^[13] — forum). Community members praised the vibrant colors, thriving reef, and glassfish scenes (^[14] — forum).

Forum member Namton posted wide-angle photos from a 2021 New Year trip covering Richelieu Rock, Koh Tachai, Koh Bon, and the Similan Islands over 4 days and 14 dives, using a Sony A7RIII with Canon 8-15mm fisheye in a Nauticam housing with dual Sea & Sea YS-D3 strobes (^[15] — forum).

Andaman Sea — Southern Sites

• Hin Daeng / Hin Muang — Deep southern Andaman sites known for manta rays and vibrant soft coral walls. Frequently mentioned alongside Similan liveaboard itineraries and listed among top ten worldwide dive sites by multiple forum members (^[16] — forum, ^[17] — forum). One member noted that Hin Muang was unfortunately “destroyed in 2007” (^[18] — forum).

• Koh Haa — An archipelago south of Phuket near Koh Lanta, described as “pretty, few divers” with 25-meter visibility (^[19] — forum).

• Phi Phi Islands Marine Reserve — Featured in multiple Earth Touch Wild Oceans episodes filmed in the Andaman Sea. The marine reserve yielded 4K footage of scribbled filefish, bigeye snappers, mating leopard sharks, cuttlefish laying eggs, tiger-tail seahorses, and “bizarre pufferfish behaviour” (^[20], ^[21]).

• Shark Point — A dive site near Phuket with variable visibility (as low as 15 meters) (^[22] — forum).

• Racha Noi / Racha Yai — Islands south of Phuket offering day-trip diving with good conditions (^[23] — forum). Koh Racha Noi, located thirty miles off the southwest tip of Phuket, was featured in an Earth Touch Wild Oceans episode showcasing mantis shrimp, bearded scorpionfish, powder blue surgeon fish, redtail butterflyfish, and pufferfish in “ultra HD” — described as “like diving in an aquarium” (^[24]).

Andaman Sea — Phuket Area

• Kata Reef — A shore-accessible site near Phuket featured in Earth Touch’s Wild Oceans series. Underwater cameraman Nicolas Lurot captured footage of a mimic octopus evading a lionfish, a giant frogfish walking along the seafloor, a pineapplefish, bluestriped fangblennies, and a rare paddle-flap rhinopia (^[25]).

• King Cruiser — A wreck dive near Phuket with “very random” visibility (as low as 7 meters) (^[26] — forum).

Gulf of Thailand — Koh Tao

Koh Tao, on the east coast in the Gulf of Thailand, is primarily known as a diver certification hub rather than a photography destination. Drew Wong described it bluntly: “If you’re into young people partying and diving in urchin fields and broken coral, it’s fine” (^[27] — forum). Multiple forum members characterized it as “a divers factory” that provides the greatest number of certifications in Southeast Asia at budget prices, with one member noting “I sometimes felt I was grandpa at the beach” (^[28] — forum).

Two sites near Koh Tao were noted as exceptions worth visiting:

• Chumphon Pinnacles — Known for shark sightings, including bull sharks at the base of the pinnacle. Wong noted it has “the occasional whaleshark and sailfish.” Forum member luko confirmed seeing “those large bulls at the bottom of the pinnacle even though at this time everybody on the island thought they were grey reefs on steroids” (^[29] — forum).

• Sail Rock — A site with a swimthrough that is “nice when there’s schooling fish around” (^[30] — forum).

The community consensus was clear: “Koh Tao is very good destination for learning how to dive but it is not top class diving comparing to the Andaman sea sites” (^[31] — forum). Forum member khunneal recommended: “If you want to party and go scuba diving, I’d suggest Phi Phi instead. If you just want to dive, stay in Phi Phi or Phuket” (^[32] — forum).

2004 Indian Ocean Tsunami

The December 26, 2004 Indian Ocean tsunami was the single most devastating natural disaster covered in the Wetpixel archive, and Thailand was at the center of the community’s experience. Several Wetpixel members and their friends were in the affected areas, and the forums became a focal point for sharing information and confirming safety. Eric Cheng posted a call for donations to Save the Children and the American Red Cross on December 29, 2004 (^[33]).

Eyewitness Accounts

Jason Heller was diving at Richelieu Rock when the tsunami struck. Underwater, he experienced the wave as an abnormally strong current: “I literally had to pull myself across the bottom of the ocean floor, hand over hand, to keep from being washed into the current.” Upon surfacing, extreme tidal anomalies were visible — Richelieu Rock, which Heller said normally protrudes about 10 feet at high tide, was exposed by more than 15 feet, then “disappeared under the sea” as a whirlpool formed. His crew cut their mooring rope and spent a harrowing night at sea receiving warnings of further waves. He described the night: “Every 10 or 20 minutes for the next 3 hours, we received frantic warnings of the eminent wave coming our way. Passengers were saying their last goodbyes” (^[34]).

Heller and his fiancee subsequently documented the devastation at Khao Lak, the area hardest hit in Thailand, where destruction extended more than a mile inland. He described makeshift morgues, monks accompanying scuba divers searching a lake where a bus of tourists had been washed, and “the stench of decomposing bodies” everywhere. His account was published on Wetpixel on January 4, 2005, introduced by Eric Cheng as written by “my good friend Jason Heller” (^[35], ^[36]).

On the forums, community member Leslie started a “Tsunami: any word from our friends?” thread on December 27, 2004, which became a clearinghouse for information. Herb Ko sought news of friends on a Similan liveaboard, and community member “marjo” reported that divers on boats at sea “did not understand what had happened, because at sea they didn’t notice a thing,” though some divers at the Emerald Caves apparently died (^[37] — forum). John Williams of Siam Divers posted a detailed account confirming that “as far as we know, there have been no accidents at sea involving divers” and that “the people who were killed or injured were on the beach or close to shore at the time the wave hit, as there was little or no warning,” calling it “Phuket’s first ever tragedy in the 17 years that Bent and I have been here” (^[38] — forum).

Impact on Reefs and Dive Industry

An “Effect of Tsunami on Marine Life” thread sparked debate about the ecological impact. The liveaboard operator Ocean Rover, which assisted CBS News crews to the Similan Islands, was furious when CBS produced a misleading report about coral damage: “The CBS piece is damaging to our reputation and business. It paints the wrong picture about the true level of coral damage in the Similans.” Ocean Rover’s cruise director Hans Tibboel had described only one dive site at Surin Island where “it looked like a giant sandblaster was used,” while noting the “actual lack of damage at other places.” CBS used the footage in a deceptive “before & after” presentation where “all the beautiful ‘before’ footage shown by CBS was actually filmed AFTER the tsunami” (^[39] — forum).

Community member Leslie provided scientific perspective, noting the reef damage was compounded by “several meters of mud & debris laced with sewage and chemicals” and that recovery would depend on proximity to healthy coral populations, with the shortest recovery time ever reported being about 20 years (^[40] — forum).

Nick Hope uploaded post-tsunami video from the Similans on January 15, 2005, showing hard corals in good condition at East of Eden. He described his video as “an attempt to counter inaccurate tales of total devastation with a bit of hard evidence” (^[41] — forum). Drew Wong, who was on the ground helping with cleanup, reported that the damage was “pretty much consistent with strong surge/storm damage” and that a coral-righting effort had been stopped “since it was doing more damage than good.” Wong noted “there are enough dive sites not badly affected by the tsunami in the similans and surins” (^[42] — forum).

Ocean Rover emphasized the economic importance of continuing tourism: “The last thing Phuket needs right now is an economic meltdown caused by tourists staying away as a result of inaccurate news coverage. Thousands of ordinary Thais are employed in the resorts that are now damaged and closed” (^[43] — forum). The liveaboard continued its Thailand-Myanmar cruise schedule without changes, with the sole exception of a special Andaman Islands cruise cancelled because “the Indian Government closed the area for foreign flagged shipping” (^[44] — forum).

Post-Tsunami Recovery and Ecotourism

In the wake of the tsunami, conservation-oriented projects emerged. At ADEX Bangkok 2007, the Ecotourism Training Center (ETCTH), founded by Reid Ridgway, was highlighted for training local Thais for eco-tourism jobs including dive mastering. Wong noted a persistent issue: “One of the biggest sore points of the Thai diving industry is that most of the dive masters and guides are foreigners” despite Thailand certifying more PADI divers than any other country. Ridgway “started this project after the devastating tsunami hit the west coast of Thailand in 2004” (^[45]).

Coral Bleaching and Conservation

Thailand’s reefs have been repeatedly affected by coral bleaching events documented on Wetpixel:

• 2010: Bleaching struck 90 percent of coral reefs around Phuket, with 10 to 40 percent suffering irreversible damage due to warmer-than-normal water temperatures. The entire Andaman region’s reefs were at risk. Scientists measured reef temperatures at 30.5 degrees Celsius (^[46]). Adam Hanlon questioned whether the cause was El Nino rather than “hot sun” as initially reported (^[47]). This was part of a region-wide event identified as “certainly being the worst since 1998,” with sea temperatures rising by as much as 4 degrees above normal from the Seychelles to the Philippines. Dr Andrew Baird of James Cook University warned that “coral cover in the region could drop from an average of 50% to around 10%” (^[48]).

• 2011: In response to the 2010 bleaching, seven coral reef sites off Phuket and the Andaman Coast were closed to divers on January 21, 2011, with closures intended to last up to five years. Affected sites included Mo Koh Surin Island, Mo Koh Similan (East of Eden, Ao Faiwab), Phi Phi (Hin Klang), and sites in Krabi, Satun, and Chumphon provinces. Penalties ranged from 1,000 to 10,000 baht (^[49]). In the comments, a reader questioned the value of banning divers, and Hanlon explained that “bleached corals within Marine Protected Areas recover faster than coral outside MPAs where diving, fishing and other human activities occur” (^[50]).

• 2016: Thirty-two dive sites in both the Gulf of Thailand and the Andaman Sea were closed to divers after water temperatures of 29.2 degrees Celsius to 31 degrees Celsius were recorded at shallow depths — “significantly higher than normal” (^[51]). Also in 2016, Exposure Labs (makers of “Chasing Ice”) sought volunteer underwater photographers to document coral bleaching globally, including in “Thailand - Andaman Sea” (^[52]).

Shark Conservation

In 2011, the organization Dive Tribes announced the Great Shark Release, scheduled for September 3, aimed at releasing sharks rescued from restaurants and pet stores in Thailand back into the ocean. Dive Tribes described it as potentially “one of the largest shark releases ever staged,” with RF trackers fitted to each shark and a team of marine biologists and shark specialists ensuring no harm during the release (^[53]).

Underwater Film and Video

Thailand — particularly the Andaman Sea — has been a prolific location for underwater video production featured on Wetpixel.

Nick Hope / Bubble Vision

Nick Hope, a Thailand-based Wetpixel member and videographer, produced “Reef Life of the Andaman,” a 116-minute documentary filmed over the course of more than 1,000 dives at the Similan Islands, Phuket, the Phi Phi Islands, Hin Daeng/Hin Muang, the Mergui Archipelago, and the Burma Banks. The film featured marine life “from seahorses to whale sharks.” It was released on YouTube in 2012 and was also available on DVD at 14.95 GBP. Hanlon called it “a top class DVD” (^[54]).

Hope also posted a showreel in April 2012 featuring stock footage from Thailand, Myanmar, Indonesia, Fiji, and Tonga, shot with a Sony HVR-Z1P camera in 1080-50i and 1080-60i HD. Hanlon noted “the images are spectacular” (^[55]).

Earth Touch Wild Oceans Series

The Earth Touch Wild Oceans television series produced multiple episodes filmed in Thailand’s Andaman Sea, all featured on Wetpixel:

• Kata Reef, Phuket — mimic octopus, giant frogfish, rhinopia, filmed by Nicolas Lurot (^[56])
• Phi Phi Marine Reserve — filefish, bigeye snappers in 4K (^[57])
• Phi Phi Islands — mating leopard sharks, cuttlefish, tiger-tail seahorse (^[58])
• Koh Racha Noi — mantis shrimp, bearded scorpionfish, pufferfish in ultra HD (^[59])
• Lionfish footage by Stewart Whitehead (^[60])

Note: The lionfish episode article states it was filmed “in Thailand’s Sogod Bay.” Sogod Bay is geographically in Southern Leyte, Philippines, not Thailand. This appears to be an error in the original Wetpixel article.

Community Video Showcases

Forum member OliveB posted video from a March 2022 mixed diving trip (half dive center, half liveaboard) covering Krabi, Koh Lanta, Koh Haa, Phuket sites, Similans, and Richelieu Rock. Shot with a Canon 1DX Mark II in a Nauticam housing with Sigma Art 20mm lens and no additional lights, the video drew praise for color reproduction. OliveB described being most impressed by “the diversity of the coral, the colors, the underwater landscapes, hunting scenes and Richelieu Rock.” He confirmed achieving the color results without any filter, doing “the white balance manually by filming a white board down there” (^[61] — forum).

Forum member “Aquatic Images” posted a 4K promotional video for a Similan Islands liveaboard company in 2020, which drew praise as “a piece of art” from other community members (^[62] — forum).

Mergui Archipelago (Myanmar, accessed from Thailand)

The Mergui Archipelago in Myanmar, typically accessed via liveaboard from Thailand, was the subject of a comprehensive photography preparation guide by Franck and Camille Fogarolo of The Smiling Seahorse liveaboard, published on Wetpixel in 2020. The Smiling Seahorse has been “the only liveaboard operating exclusively in Myanmar since 2012.” The archipelago offers diving from October to May with water temperatures of 27-30 degrees Celsius and visibility ranging from 10 to 40 meters. The guide noted that “you rarely cross paths with another dive boat” and that “Myanmar is the place where you will enjoy being alone on every dive site” (^[63]).

Key sites include Black Rock — described as “probably the best spot in Asia to see Oceanic Manta rays” — Western Rocky, the Burma Banks (underwater mountains with 40-meter visibility and large sharks), and numerous macro sites with harlequin shrimp, pygmy squid, and ornate ghost pipefish. The guide recommended a DSLR or mirrorless camera with macro (60mm or 105mm) and wide-angle (10-17mm or 10.5mm) lenses, plus external strobes (^[64]).

Nick Hope’s “Reef Life of the Andaman” documentary also covered the Mergui Archipelago and Burma Banks (^[65]).

Dive Expos and Industry Events

Thailand hosted two competing dive expos covered on Wetpixel:

• ADEX (Asian Dive Exposition) — Held at BITEC convention center in Bangkok in 2007, featuring exhibitors from across Asia. Drew Wong organized a Wetpixel party at AD Maker bar in Lang Suan Road. The show included Gates video housing prototypes (FX7 and HC7), Seatool housings brought by founder Kenji Ohmura, and multiple Wetpixel community members including Tony Wu. Nick Hope was photographed with the new Gates HC7 housing and lights system. However, the inconvenient BITEC location drew criticism — Wong noted “the general feeling was that ADEX wasn’t as good at BITEC as when it was held in Central Bangkok” — and community member PeterBKK noted ADEX was competing with TDEX, to be held at the more central Queen Sirikit Convention Center (^[66]).

• TDEX (Thailand Travel & Dive Expo) — The 7th TDEX was held July 8-11, 2010, in Bangkok. Tony Wu and Eric Cheng both spoke on the mini stage at 2pm and 5pm on July 10-11, with a Wetpixel / Tony Wu meet-up planned at Baan Khanitha restaurant on Friday evening (^[67]).

• Dive Guide Thailand Photo Competition — A free monthly competition launched in 2009, hosted on Flickr, with Thailand dive trip prizes. Judged by Alex Mustard (^[68]).

Publications

• Pocket Guide: Dive Thailand 2011-12 — Written by underwater photographer Paul Lees, covering each diving destination with dive site maps, descriptions of popular sites, and featured dive centers. Available in print and as a free PDF download (^[69]).

Liveaboard Operations

Multiple liveaboard operators serving the Similan-Surin-Burma route were discussed on the Wetpixel forums. Recommended boats included:

• Ocean Rover — Described by one member as “absolutely the best liveaboard in Phuket.” The boat was at the center of the post-tsunami media controversy and continued operations without schedule changes after the disaster (^[70] — forum, ^[71] — forum).

• Mermaid boats — Recommended by forum member stewsmith (^[72] — forum).

• West Coast Explorer, Black Manta, Colonna VI, Genesis — Drew Wong provided detailed comparisons, rating the Black Manta as “upper mid range and the nicest of this lot if you get the master cabin” and noting that the Explorer and Genesis had shared bathrooms. He characterized them as “good and safe” (^[73] — forum).

• Similan Diving Safaris — Operating from Khao Lak, recommended as “on the cheaper side but excellent” (^[74] — forum).

• Pawara — Described as “aiming at the Ocean Rover / Philkade market, but prices still midrange” by forum member taxgeek, who noted it featured universal electrical outlets and let experienced divers “stray a bit from the dive group” (^[75] — forum).

• MV Andaman — Used by forum member Freelio in 2022 (^[76] — forum).

• Deep Andaman Queen — Used by forum member Namton on a 2021 New Year trip covering Richelieu Rock, Koh Tachai, Koh Bon, and the Similan Islands (^[77] — forum).

Standard liveaboard itineraries run from Khao Lak or Phuket and cover the Similan Islands, Koh Bon, Koh Tachai, Surin Islands, and Richelieu Rock over 4-7 days. The diving season runs roughly from October/November through April/May (^[78] — forum, ^[79]). Drew Wong advised booking before arrival rather than seeking on-the-ground discounts: “unless you are there and sitting around until you can hop on a boat… it’s not worth the hassle of running around looking for boats” (^[80] — forum).
