Thailand Whale Shark Diving expedition, March 2026 North and South Andaman
A special 8 days/ 7 nights North and South Andaman cruise to know more about whale sharks in Thailand
Who are our partners for this new discovery cruise?
Thailand Whale Shark project:
Started in 2017, Koh Tao Whale Sharks was started by Marine Biologist and Conservationist Kirsty Magson to assess and monitor the population of whale sharks around Koh Tao and the surrounding area. After the success of the project and will over 280 positively identified individuals found, Koh Tao Whale Sharks became Thai Whale Sharks. The goal of Thai Whale Sharks is to build on the success and begin to monitor and map the movement of individual, understand more about the habitat use and time at location and to distribute code of conduct and learning resources for businesses that interact with these animals. Thai Whale Shark aims to record all whale shark sightings in Thailand in partnership with the worldwide database of The Wildbook for Whale Sharks photo-identification library. They are looking to understand more about these animals and their populations around Thailand by using Citizen Science to help them to gain information. Any person that spots a whale shark and has a photo to go alongside it, is able to submit their sighting to either their Facebook page or their email. Once these images are submitted they are then able to run the image through their database as well as the global database of whaleshark.org to find a match.
These matches are only possible due to the unique spots and stripes along the body of the whale shark. These patterns are much like human finger or thumb prints and enable them to identify the animal to an individual level. Photos of the left hand side of the animal in between the gills and the dorsal fin is the ID Location as well as any distinguishing scare or blemishes, the estimated size of the animal and the dive site it was seen. |
The library is kept up to date by an army of Marine biologists researcher to gather and dissect whale shark locating information to get familiar with these stunning animals.
The Wildbook utilizes photos of the skin designing behind the gills of each shark, and any scars, to recognise singular creatures. Forefront programming upholds quick recognisable proof utilising design acknowledgment and photograph the board devices. You also can help with whale shark research, by submitting photographs and locating information. The data you submit will be utilized in imprint recover studies to assist with the worldwide preservation of this compromised species. |

In the North Andaman, we will visit Surin and Similan National parksSIMILAN NATIONAL PARK:
Koh bon is a well known cleaning site for Manta Rays and the site most frequented by them in Thailand. There is also a good chance to spot a Zebra Shark on the pinnacle. Koh Tachai Pinnacle is a very fishy dive: beside Whale sharks and Manta rays, we can see schools of barracudas, giant trevally, blue fin trevally, sweetlips, batfish, tunas in the blue.
We will also visit some dive site in the south of the Similan National Park. Your cruise director will choose from a variety of dive sites and we will keep in touch with other boat if Whale sharks have been sighted in the last few days. If some are gentle giants are sighted, we may stay put to spend a few dives with them. The visibility is usually excellent around the Similan islands and we hope to spot leopard sharks, blue spotted stingray, school of snappers and fusiliers, emperor fish, clown trigger fish and more tropical colourful fish as well as some Moray eels, turtles and mantis shrimps living in the rocky areas. Whale sharks are also commonly spotted there so keep an eye being your head for a gentle giant passing above! |
SURIN NATIONAL PARK:
Less know but unmissable! Especially Richelieu Rock, still listed in the top 10 dive sites in the world! And you will quickly understand why! Not only is it a great place to see Whale Sharks but it can also be described as a big aquarium with more or less everything … from seahorses to jack fish and plenty of kinky cuttlefish action and we hope again a sighting of something big in the blue... The rest of Surin Island, not dived by many other boats but it is a very good spot for macro life such as ghost pipe fish, frog fish and nudibranchs and the first place where we can see Whale Sharks and Mantas. There are also many Jenkins Stingray, sweetlips and Barracudas around and the regular sighting of Humphead Parrotfish, Eagle Ray and Reef Sharks. |
In the South Andaman, we will visit:
- Hin Daeng and Hin Muang (Red rock and Purple rock), not far from Malaysian border, are amazing dive sites, offering steep walls, big fish and colourful soft coral. Both Mantas and Whale sharks are sighted there regularly next to many smaller pelagics such as tunas, schools of Jack, barracudas and Leopard sharks.
- Koh Haa is more famous for its massive cavern systems (in which you can even see massive stalactites)
If we hear of whale Shark sighting near Koh Lipe, we may also take our boat in this direction!
Our boat: MV Smiling Seahorse, the newest liveaboard around!
Built by and for divers in 2018, the MV Smiling Seahorse is the newest dive boat currently cruising the Andaman sea
The Smiling Seahorse has been operating since 2012, we organize dive cruises from 3 to 14 days from Ranong both in Thailand and Myanmar. MV Smiling seahorse, was built by and for divers and took its maiden voyage in November 2018.
We added all the "little extras" you may want on a new liveaboard: a spacious dive platform, a camera room, lovely lounge areas, a massive sun deck, 8 cabins for only 16 guests all with large windows and doors to the ocean.
We keep dive small groups and organize each group to stagger their gear-up and entry times to ensure that the already spacious dive deck never has too many bodies moving around at once. While your group is ready to jump in for a dive, the next group will be doing safety checks and the following group is still upstairs taking their last sips of water during their dive briefing. Everyone is a VIP on the MV Smiling Seahorse!
