Diving Tours to Koh Tao

In Koh Samui, scuba diving tours to Koh Tao are most popular due to the great diving conditions, array of fascinating dive sites and awe inspiring underwater natural beauty.

Whether you’ve just passed your Open Water course or you’re a seasoned diver, diving tours to Koh Tao have something for everyone.

With unique boulder formations and soft & hard coral, Koh Tao is much further away from the main land than any other island, and it’s surrounded by deeper water. That means all the sediment flowing from rivers to ocean has a chance to sink to the bottom and that’s why Koh Tao has the best visibility in the Gulf of Thailand.

Interested in a long relaxing shallow dive? Japanese Gardens, Aow Leuk, Mango bay and Hin Wong bay may be for you. Twins and White Rock could be the ticket if marine life or underwater photography is your thing. Or do you like exploring swim-throughs and caves? There’s plenty to be found at Laem Thian, Green Rock and Red Rock dive sites. Then there’s a few special sites: a purpose sunk shipwreck, the HTMS Sattakut, a Thai navy frigate just south of White Rock and Chumphon Pinnacle where depths reach down to 40m and frequent visitors include whales sharks, bull sharks and reef sharks.

All of these dive sites and more are on offer with our diving tours to Koh Tao. The service you choose really depends on your budget, the time you have available and where you’d like to dive. Speed boats can often go further afield from side of the island to the other to take in the best diving spots – small numbers on the boats means you are able to do that and moor up close. The larger boats are less able because of speed but there are still plenty within easy reach, the slow pace is conducive to a more relaxed day and lots of space on the boat makes for a better overall experience.

Whatever service you choose, all are professionally operated. You’ll have experienced dive guides with you and be supplied with all the necessary equipment and a tasty Thai buffet for lunch.

What more can we say? A Koh Samui diving tour to Koh Tao will be an experience not soon forgotten. Book today with Samuipedia – these tours have heavy demand so be sure to book a few days in advance.

About Diving in Koh Tao

Second only to Cairns in the whole world for new scuba diving certifications issued, Koh Tao is packed full of dive sites that suit all levels of scuba diver from beginner to advanced.

Koh Tao, or Turtle Island, together with Koh Nang Yuan (Seagull Island) a stones throw to the north west of Koh Tao, is located 70km north of Koh Samui and takes approximately 1 hour and 30 minutes by speed boat, the best and most convenient way to get there. It is due to its position further away from the mainland and being surrounded by deeper water than Koh Samui or Koh Phangan that gives Koh Tao the best water visibility in the Gulf of Thailand, where the underwater visibility ranges from 5m up to 30m, depending on time of year, local weather and lunar cycles.

The sites visited by our scuba diving service change depending on the time of year. From October to March, the tour stays to the west and south coasts of Koh Tao. From April to September, you will tour the more undeveloped north and east coasts of Koh Tao, which present beautiful, untouched mountainous scenery and lesser visited scuba diving sites. In November, the visibility is typically reduced due to monsoon season weather however this is not always the case as in recent years the monsoon has either been absent or has shifted, so please contact us for the weather outlook at this time of year or see the weather forecast for Koh Samui.

Our scuba diving tours from Koh Samui by speed boat specialize in tailoring the scuba diving to your needs and interests.

  • All over Koh Tao, there are sites ideal for both snorkeling and diving, with crystal clear water and beautiful coral, teeming with stunning and friendly marine life. This is perfect if you have a group where some of you want to dive and some of you want to snorkel.
  • There are some sites more suited to underwater photography, that have more colorful or more interesting coral and a variety of marine life that is easy to come upon and photograph.
  • Koh Tao typically consists of boulder fringed bays, some of which are perfect for finding small caves and swim-throughs to navigate.
  • There are a couple of wrecks around Koh Tao, the easiest to get to and most impressive is the HTMS Sattakut, a Thai navy frigate sunk in the middle of 2011.
  • There are also sites that are simply more fun, one such site, Twin Peaks, has several features such as a buoyancy park (series of hoops and loops to swim through to test your buoyancy) and concrete sculptures in the shape of various creatures (turtle, shark, godzilla(!), batfish, octopus) which are part of a project to attract new coral growth and relieve stress from the main dive site.

About the Diving Service to Koh Tao

Our scuba diving service owns their own speed boats where many do not, as such control where they go. Koh Tao gets very busy around some of the dive sites, so the speed boat has the versatility to go elsewhere.  A lot of scuba diving operators make the journey from Koh Samui to Koh Tao everyday, however most do not own their own speed boat, using chartered speed boats specifically for scuba diving, where there will be several diving companies all on the same speed boat and going to the same dive sites every day.

The speed boats used by our scuba diving service, are use as a vessel for transfer from Koh Samui to Koh Tao & Koh Nang Yuan for our snorkeling and scuba diving customers. When the speed boat arrives in Koh Tao, both parties split up to do their respective activities. The snorkelers go on to the islands to go sightseeing and snorkeling from the beaches, leaving the speed boat completely free for the scuba divers. Typically there are between 2 and 8 divers each day, which means there is plenty of space on the boat and the diving is much more personal.

Also as our snorkeling and scuba diving customers go on the same boat together to Koh Tao and Koh Nang Yuan, groups where there are snorkelers and scuba divers can stay together.

We have worked closely with our preferred scuba diving operator for a long time and personally know each of their scuba diving instructors and tour guides, who have lived and worked in Koh Samui for a few years, so we can say with some level of authority that they are the most experienced and knowledgeable on Koh Samui.

Can I Dive in Koh Samui

There are actually some fantastic things to see underwater around Koh Samui. They are often quite different from what you might see in Koh Tao, which makes the diving in Koh Samui very interesting and some schools do offer this service. Also as the dive sites are on our doorstep, the scuba diving is much cheaper as there is no gasoline to pay for a long journey.

The problem is the visibility and the predicting of it. The best visibility to expect around Koh Samui is 6-8m but is usually 1-3m. This is due to its relative proximity to the mainland of Thailand and the relatively shallow depth of the water between Koh Samui and mainland Thailand, meaning sediment from rivers carries a lot further reaching Koh Samui. At certain times of the year, March to October, there is more likely to be better underwater visibility around Koh Samui but this is frequently not the case, thus why we recommend Koh Tao for our customers.

What if I don't have a Diving License?

The first question you will always encounter from any PADI or BSAC dive center is: "Are you certified?". If you aren’t, don’t worry, we just need to know this so we can arrange for a PADI or BSAC instructor to go scuba diving with you. Also if you aren’t qualified yet, it means PADI instructors can only take you to a maximum of 12m, rather than 18m for qualified scuba divers. If you’re already qualified, skip to the "I Have a Scuba Diving License" section.

If you don’t have a scuba diving license, check out our Scuba Diving for Beginners page.
