Why Learn to Dive on Koh Tao?

Koh Tao is more than just a beautiful tropical island in the Gulf of Thailand. Not only is it one of the best places to learn to dive in Thailand, it’s also one of the most popular places in the world to learn to dive. Every year, more people earn their first diving certification here than anywhere else on the planet.

So, what makes this little island such a big name in the diving world?

First, location plays a huge role. Koh Tao sits right on the classic backpacker route through southern Thailand, which means it’s pretty easy to fit a trip to Koh Tao into a travel itinerary. And with the variety of available scuba courses on Koh Tao, you can choose a course based on how long you’ll have on the island.

Second, the island’s underwater topography creates almost perfect learning conditions for beginner scuba divers. The Gulf of Thailand is relatively shallow, averaging just 45 meters in depth, with a maximum depth of 80 meters in the centre of the Gulf channel. This produces calm, sheltered waters that can be more like a giant bathtub than the wave and current-exposed sites you’ll find on Thailand’s west coast.

Because of these two reasons, Koh Tao offers fairly stable and comfortable diving year-round. Whether you’re planning your trip in peak season or the quieter months, you can count on warm water and a safe environment for learning to dive.
One of the other big advantages of choosing to learn to dive on Koh Tao is affordability. Courses here are typically much cheaper than in other parts of the world, without compromising on safety or instructor quality. This makes Koh Tao a world-class yet budget-friendly destination to begin your scuba journey.

Koh Tao Scuba Diving for Beginners

Koh Tao has earned a reputation as one of the best places to learn to dive in Thailand, offering a wide range of scuba courses that make it easy for anyone to get started. Whether you want to simply try scuba diving in a controlled environment or earn a full certification that allows you to dive worldwide, Crystal Dive has training perfectly suited to your needs and goals.

Here’s an overview of all the scuba course options at Crystal Dive Koh Tao:

SSI Try Scuba

This is an easy and relaxed basic introduction to scuba diving, ideal for anyone curious about what it feels like to learn to dive on Koh Tao. Conducted in confined water (like a swimming pool or shallow bay) to a maximum depth of 5 meters, you’ll get a taste of using scuba gear and breathing underwater.

Try Scuba is a non-certification activity designed for beginners who want to explore scuba in a safe and supportive environment.

SSI Basic Diver

If you’d like to experience scuba diving for beginners in the open ocean without committing to a full course, the Basic Diver program is a great choice. After a short confined water session and a touch of theory to learn the essentials, you’ll join your instructor for at least one guided dive in the open ocean (to a maximum depth of 12 meters). While this is still a non-certification option, it’s a fantastic way to find out if learning to dive is right for you. Even better, the Basic Diver can be credited toward the SSI Open Water Diver, the most popular scuba course on Koh Tao, as long as you complete it within 6 months.

This is also a great time for new divers to complete certification courses since conditions are generally decent, and there’s more flexibility in scheduling. Most overseas visitors find the water temperature quite comfortable and dive in just a bathing suit (although our staff may show up in wetsuits on some days).

If you want fewer crowds but still great visibility, this shoulder season might be the best time to dive Koh Tao for you.

SSI Scuba Diver

The Scuba Diver course is a “halfway” certification designed for people who want more than a one-day learning to dive experience but aren’t ready to complete the full Open Water course. Over 2 days, you’ll learn the basics and complete training dives that will bring you down to 12 meters under instructor supervision.

Many divers later build on this by continuing to the full Open Water course when they’re ready.

SSI Open Water Diver Course

The SSI Open Water Diver course is the most popular choice for those who want to learn to dive on Koh Tao. Over 3 days, you’ll combine theory sessions, confined water practice, and four open water dives. By the end, you’ll be a certified scuba diver able to dive to 18 meters anywhere in the world.

This is the go-to beginner scuba diving option for travelers who want a globally recognized scuba certification and a solid foundation in recreational diving.

The Best Dive Sites for Beginners on Koh Tao

One of the reasons Koh Tao is such a popular place for scuba diving for beginners is its huge range of calm, shallow dive sites that are perfect for training and building confidence. When you’re learning to dive, having gentle conditions and great visibility makes all the difference, and Koh Tao delivers on both.

Best of all, even as a beginner, you could be treated to incredible underwater surprises. Koh Tao gets visits from whale sharks all year-round. While it’s not guaranteed, it’s also not unheard of for brand-new divers to see one of these incredible creatures during a training dive.

Mango Bay is a large, sheltered bay with sandy bottoms and shallow coral reefs, making it an ideal first open water dive. It’s easy to practice basic skills here while enjoying colorful reef fish and vibrant corals in the calm water. Lucky learners might even spot a sea turtle cruising around the coral patch.

Japanese Gardens is another favorite for beginners, located next to the Insta-famous Koh Nang Yuan island. With shallow depths, generally great visibility, and loads of tropical reef fish, it’s like swimming in a giant natural aquarium.

Twins is a must-visit for both new and experienced divers. With three distinct pinnacles at three different depths, this site offers a mix of sandy patches and hard coral formations that often hide moray eels and stingrays. If you become an advanced diver, Twins is an excellent site to see octopus and cuttlefish during a night dive.
