An In-Depth Look at the Koh Tao Open Water Course

Starting with Confidence: Pool Sessions and Classroom Learning

The course kicks off with an afternoon orientation at 4:00 PM, giving you a chance to meet your instructor and get a feel for the schedule ahead. The following day begins at 10:00 AM with a classroom session. Here, you’ll learn the fundamentals, like how diving affects your body and essential safety procedures. We loved how clear and approachable the explanations were—especially appreciated by those new to the sport.

Next up is the pool session, where you’ll practice basic skills like mask clearing, regulator retrieval, and emergency procedures. The small group size (often just 4 participants) ensures you get personalized guidance, making it easier to master these skills. As one reviewer noted, “Theory and exam were easy enough, so don’t stress about that.” This structured approach helps build confidence before heading into open water.

Transitioning to Open Water: The First Dives

On the third day, after a morning classroom session on how diving influences the human body and navigation techniques, you’ll head out on the boat for your first open water dives. These dives are typically to a maximum depth of 12 meters, ideal for beginners. Expect to see stingrays, pufferfish, moray eels, and a vibrant array of reef fish that will leave you amazed.

The boat rides themselves are smooth, with many reviews highlighting the professionalism of guides like Julián and Martín. One reviewer from Spain mentioned Julián’s exceptional teaching style and personal approach, which made the experience memorable. The boat typically departs around 9:30 AM, giving you a full day of underwater exploration.

Exploring Deeper and Larger Marine Life

Your final day begins early at 7:45 AM, with two more dives at slightly more advanced sites. Here, you’ll encounter larger marine animals, such as barracudas, queenfish, and, with a bit of luck, whale sharks. Although sightings of the latter are rare, the possibility adds a sense of anticipation.

This day allows you to apply everything you’ve learned—navigating, managing buoyancy, and handling potential issues—under the supervision of skilled instructors. Completing these dives means you’ll earn your Open Water Diver certification, valid up to 18 meters anywhere in the world.

What Makes This Course Stand Out?

Expert Guides: The reviews consistently praise guides like Julián, Martín, and Joe for their patience, knowledge, and personable approach. Their ability to explain complex safety procedures clearly is a big plus.

Stunning Marine Environment: Koh Tao’s waters are known for their diverse marine life and clear visibility. You’ll love the chance to see stingrays, moray eels, and reef fish during your first dives, with the possibility of spotting bigger creatures on later dives.

Value for Money: For a comprehensive 4-day course—including classroom, pool, open water dives, and certification—the price offers solid value. The convenience of a local, experienced operator like LBD Diving Koh Tao, who also offers free hotel pickup, adds to the overall experience.

Flexible Booking and Cancellation: With options to reserve now and pay later, and full refund if you cancel 24 hours in advance, planning your trip becomes less stressful.

Practical Aspects and Logistics

The schedule is quite compact, with the entire course lasting about 3.5 days. This means you’ll need to dedicate significant time over these days but can still enjoy other island activities afterward. The small group size enhances the learning experience and ensures you get plenty of attention.

Transportation is straightforward, with hotel pickup included in many packages, making logistics hassle-free. The instructors speak Spanish, English, and Catalan, accommodating a diverse range of travelers.

Reviews: Authentic Insights from Past Participants

Many reviewers, such as Alex from the UK, noted that the instruction was patient and knowledgeable. Alex mentioned that “The 4-day course definitely seemed worth it over the try-diving experience,” emphasizing the value of a full course over quick introductory sessions.

Another traveler from Australia highlighted the positive atmosphere created by Martín, calling him “incredible” and appreciating how well he explained everything. The small group size and personalized attention clearly make a difference.

One reviewer from Denmark called the experience simply “Mega positiv”, capturing the general enthusiasm for the course and guides. Many expressed surprise at how accessible and enjoyable the learning process was, even for complete beginners.
