What a wonderful experience!
A friend and I booked the open water certification having no prior experience with scuba. Our instructor, Roni, was clear and helpful when preparing us for our sessions in the water. Once we did our first water session all worries I had about diving faded away and by day 3 I was so thankful I chose to dive in Koh Tao!

Koh Tao Divers truly offered one of the best learning experiences I've ever had. The XR Sidemount Course was organized professionally, maintaining a perfect balance between education and enjoyment. I must mention my instructor, Naomi, who demonstrated commendable expertise and patience throughout the course. Kudos to the entire KTD team for creating such an amazing environment. Highly recommended!

Vera and I completed the best Kiss Sidewinder CCR training we could have wished for with Mikko Paasi. Mikko prepared us well for all possible scenarios. His teaching methods were always memorable and effective. A special thanks goes to the entire team at Koh Tao Divers - KTD.

Thank you for the great training! We are coming back to Thailand to embark on new adventures with you.

Koh Tao diving FAQ


Why is Koh Tao a top destination for diving?

Koh Tao offers a unique combination of year-round diving conditions, a welcoming island vibe, and a community of like-minded divers. The island’s long diving season, with calm seas and excellent visibility, makes it ideal for underwater adventures any time of the year. Koh Tao is also home to a wide variety of dive sites, from shallow coral reefs to deep pinnacles and wrecks, catering to all skill levels. Beyond the water, Koh Tao’s relaxed atmosphere and close-knit community create a special charm that’s hard to find anywhere else. Whether you’re a beginner or an experienced diver, Koh Tao is the perfect place to explore, learn, and connect with others who share your passion for diving.

When is the Best Time of Year to Dive on Koh Tao?

Koh Tao offers diving year-round, with each season bringing its own unique appeal. The best conditions are typically from March to September, when the seas are calm, visibility is excellent, and marine life is abundant.

The monsoon season generally occurs in October and November, with heavier rains and rougher seas. By December, conditions begin to improve, but diving may still depend on daily weather patterns. While not the prime diving season, Koh Tao’s welcoming atmosphere and variety of dive sites ensure there’s always something to enjoy, whether you’re diving or simply soaking up the island vibe.

No matter the season, Koh Tao’s range of dive sites—from shallow reefs to wrecks and pinnacles—offers something for everyone. Let us know your plans, and we’ll tailor the perfect diving experience for your visit!

How Do I Book a Dive Course or Fun Dive?

We recommend confirming availability first by contacting us via email, WhatsApp or phone. Once availability is confirmed, you can secure your spot with a deposit, and pay the remaining balance upon signing up at our office. This ensures a smooth booking process and guarantees your place for your diving adventure.

Can I Fly After Diving?

For safety reasons, it’s essential to wait at least 18–24 hours after your last dive before boarding a flight. This time allows your body to safely off-gas the residual nitrogen absorbed during diving, reducing the risk of decompression sickness.

If you’re planning to fly shortly after your diving activities, let us know in advance. Our team will work with you to schedule your dives accordingly, ensuring you have ample time to meet the recommended surface interval. Whether it’s arranging your last dive earlier in the day or planning around your travel itinerary, we’re here to help make your experience both safe and convenient.

Do I Need Insurance for Diving with Koh Tao Divers?

While Koh Tao Divers provides basic accident insurance for incidents that occur during our dive trips (valid for 30 days), it’s important to note that this coverage has limitations compared to plans like those offered by Dive Assure.

We highly recommend obtaining comprehensive dive insurance.

YOU CAN BUY YOUR  INSURANCE HERE: https://app.diveassure.com/da2/en/registration/main/process/0/int/0/12416

Included Insurance for Koh Tao Divers Customers

Your included basic insurance provides:

  1. Accident Coverage: Up to 1,000,000 THB for loss of life, dismemberment, loss of sight, or permanent disability.
  2. Medical Expenses: Coverage of up to 500,000 THB per person for each accident, including hyperbaric chamber treatments for diving accidents.
  3. Exclusions: Evacuation costs are not included.
  4. Reimbursement Process: Patients must pay treatment costs upfront, and the insurance company will reimburse within 2–3 weeks.

For greater protection, including evacuation costs, we recommend comprehensive dive insurance. Plans like those from Dive Assure start at €70/year for most EU citizens and provide additional benefits, including emergency evacuations, trip cancellations, and extensive medical coverage.

Having comprehensive insurance ensures you’re fully covered, especially if you’re planning multiple dives or engaging in technical diving. Contact us for advice on choosing the best insurance option for your diving.
