Its remote island location leads it to be so peaceful and untouched.

That’s not the only reason we love its location, though! Koh Tao sits amongst the action in the Gulf of Thailand and offers some incredible diving spectacles not to be missed on any trip to Southeast Asia.

Koh Tao Scuba Certification

Scuba Certification

In general, you aren’t required to be certified in order to scuba dive on Koh Tao. In fact, there are many tour operators that cater to those of all levels of ability, no issue for a first-time diver. There are plenty of beginner-friendly and easily accessible dive sites to get your flippers wet for the first time.

What’s more, there’s plenty of opportunities to get scuba certified while you’re on Koh Tao. It’s an ideal location to learn to scuba dive, with calm conditions and many beginner-friendly dive sites. Check out our recommended open water course below to get yourself scuba certified!

Having said that, it’s always recommended to get scuba certified to give yourself the best, most enjoyable diving experience possible. While you’ll have a great time scuba diving Koh Tao as a first-time diver, there’s a lot you can miss out on without the extra confidence and diving experience, such as the more challenging cave dives and wrecks.

In addition, becoming scuba certified will help you feel more comfortable and confident underwater. This leads to maximum enjoyment and safety from your diving experience and something worth considering.

Koh Tao Scuba Diving Requirements

Scuba Diving Safety

Koh Tao doesn’t have any specific laws or regulations with regards to diving. As always, tour operators state that you must be in good physical condition and have some swimming ability. Children must be at least 10 years old to scuba dive with a tour operator.

With that said, it’s always highly recommended to have a dive buddy when you’re out scuba diving in the waters of Koh Tao, as it is anywhere else. This is particularly the case if you’re out diving without a tour operator or guide. In this situation, it’s also good practice to make use of diver down flags.

Best Sites for Scuba Diving Koh Tao

Koh Tao offers plenty in the way of a luxury island getaway, with many bucket list items available to tick off here. Diving is one of its best traits, too. It’s arguably Thailand’s top spot for getting amongst the diving action, and probably one of the best in the world. Here are some of our favorite Koh Tao dive sites.

Sail Rock

Rock Wall Diving

Dive centers in Koh Tao may be biased, but they claim they have the best day trip diving sites in Thailand.

Sail Rock (Hin Bae) is arguably one of these and certainly a contender for world-class status.

More large rock than an island, Sail Rock juts only a few metres above the sea surfaces. This inconspicuous lonesome rock, however, hides some fantastic underwater scenes. Sheer rock walls plunge vertically to the seabed 30 metres below, which in turn slopes downward to a depth of around 50 metres.

Because of its location and tidal currents, Sail Rock hosts coral on its rocky walls, a great draw for a vast array of aquatic life, including pelagics and crustaceans.

Be sure to check out The Chimney, which you can swim straight through. And for more experienced divers, the Secret Pinnacle, which lies off the main dive site.

If this sounds ideal to you, be sure to check out our recommended experience below!

Southwest Pinnacles

Underwater Rocks

Often overlooked by intermediate and advanced divers, the Southwest Pinnacles are a jaw-dropping collection of granite blocks that form a pyramid shape. These pinnacles are easily as awesome as the better known but heavier-trafficked Chumphon Pinnacle.

Ranging in depth from six to 28 metres, the Southwest Pinnacles attract a diversity of marine life. Scorpionfish are there year-round, and in-season whale sharks like to cruise around too.

Year-round, the area’s species is staggering, with juvenile yellowtail barracuda schools almost taking over the entire dive site. Also abundant are fusiliers, snappers, scad, and rabbitfish. This dive spot is also one of the very few places to see coral shrimpfish.

Thanks to the jumble of rocky hiding places, the site is home to an abundance of fish like Potato Groupers and countless aquatic critters.

There is also a ‘secret pinnacle’ off the main site, but advanced divers can only attempt this in good conditions with enriched air nitrox.

Check out our recommended experience below, this one is not to be missed on any diving trip to Koh Tao.

Sattakut Wreck

Shipwreck

The 48 metre-long wreck is that of a US Navy ship deliberately scuttled in 2011 to become an artificial reef.

It sits off Koh Tao at a maximum depth of 30 metres. Over time it has become a haven for large schools of yellowtail barracudas, fusiliers, giant groupers, moray eels, as well as anemones and coral.

Much of the wreck is still easily discernible, including a 76 mm gun on the bow and a 40 mm Bofors cannon mounted on the stern. As it is a relatively new wreck, it is possible to penetrate the vessel via a range of doorways. However, the site is recommended only for intermediate and experienced divers.

The best times to go are February through until the start of October. After this, there’s monsoon season until December.

Scuba Diving Gear in Koh Tao

Scuba Gear

There are plenty of dive shops situated on the blissful Utopia of Koh Tao so renting equipment for your dives is an option.

It’s worth noting, you’re left with one less thing to think about when going with a guided tour operator as all equipment and gear are included.

However, buying your own gear might be ideal for you if you’re a more keen and experienced diver!
