Similan Islands
The Similan Islands are one of the most beautiful destinations that you will find in Thailand.
We have outlined activities that are available, including diving and snorkelling, plus information about the sites you will see both underwater and above. There are details about liveaboards and about sailing in the Similans, with some accommodation options too. All you need to know about these stunning islands on the west coast of Thailand.
WHO ARE WE?
Thai Dive Sail offer Liveaboard diving trips to the Similan Islands in Thailand and the Mergui Archipelago and Burma Banks in Myanmar (Burma).
When planning a trip to the Andaman Sea you will encounter dozens of boats, hundreds of dive centres with one big question:
“Which one is the right one for me?“
TDS is a lot more than just a dive centre, our team work on a vast array of liveaboards for many different companies every single day, so we are able to give you individual advice and provide first hand information whether you are looking for holiday diving, wanting to charter a boat for a dive club trip or simply for an afternoon out on the Islands.
Feel free to contact us if your plans are more ambitious, such as private charters, research trips, diving for the handicapped or if you’re a professional underwater photographer in need of ‘the shot’.
We have over 15 years local experience and work only with reputable, environmentally friendly partners to ensure your perfect trip.
We are happy to arrange your trip but you can also come dive with us on a liveaboard.
Rooted with a deep devotion to the Andaman region we also run our Manta ray research expeditions and our own community projects with the goal of improving the quality of life for local indigenous populations so we can work together to create a sustainable future for the area’s environment.

“Spot on! I booked a Similan liveaboard with Thai Dive Sail and it all worked out perfectly. Their expert local knowledge shaped the whole experience into something unforgettable. In the past I used a large liveaboard booking site and turned up ill informed for my trip. Not with Thai Dive Sail, their attention to detail is clear and precise”

“I consider myself very lucky to have been on a specialised manta ray research expedition with Ric and the team. It was an experience of a life time and with so many unforgettable memories. My dreams came true when I got to dive with manta rays, not just 1 or 2 but well over 30 in a few days. Magnificent.”

Similan Diving 2018 – 2019 Report
The 2018-2019 Similan diving season had much to cheer about, been roundly observed as one of the most consistent and productive in recent years. Most notably was the coral regrowth and recovery shown in wide spread areas of the Similan Islands National Park. So what is this due too? Several key factors seem to playing a part in the recovery of this much loved national park.
Magnificent Manta Rays March 2015
Magnificent Mantas – Once Again on the MV Hallelujah. In just a few weeks Ric Parker will be heading into the Similan Marine National Park for his third presentation of See and Sea's 'Magnificent Mantas'. The Magnificent Manta Project was started by See and Sea in April 2014.
Visiting the Moken in 2015
The Ray of Hope Expedition is just around the corner and we are preparing for the See and Sea projects that will take place while visiting the Moken in the Mergui Archipelago. The Moken are a seafaring nomadic community, often referred to as Sea Gypsies.
