On the day of diving you will start the morning with a diving and safety briefing from your instructor at our office here on Lanta, followed by a fast boat journey to one of the amazing coral reefs in the Andaman Sea such as Koh Haa Lagoon or Koh Rok for example. At the beginning of the first dive, you will learn some basic diving skills in shallow water with your instructor, and then you're off exploring the same coral reefs as certified divers. You'll have a dive instructor with you at all times and can dive to a maximum depth of 12m, around 39 feet. After a delicious lunch on the boat and some time for snorkeling, we move the boat to a different coral reef where you'll go on the second dive with your instructor. If you really loved the Discover Scuba Diving introductory dives then your next step is to get certified with the PADI Open Water Diver course. We ask that all DSD participants check-in with us at our office at Castaway Beach Resort on Long Beach the day before diving before 5pm to complete the paperwork, diver medical statement, check equipment sizes, etc. This process will normally take around 30 - 40 minutes.

Open Water Course Koh Lanta

The Open Water Diver course on Koh Lanta opens up a whole new exciting underwater world of adventure with an internationally recognised diver certification. If you have ever wondered what its like to explore coral reefs, swim with turtles and possibly even spot sharks hunting in the shallows, the Open Water Diver course is for you. Certifying divers up to 18m, the many islands and coral reefs around Koh Lanta are the perfect location to learn scuba diving.

Scuba Refresher on Koh Lanta

Not dived for a while? We can help you back into the water with a Scuba Skills Refresher. Keeping your knowledge and skills up to date is a very important part of diving safely. Over time however, skills and knowledge are forgotten, resulting in problems remembering how to check equipment properly, taking a long time to descend, equalising ears, properly adjusting buoyancy and so on.

Advanced Course Koh Lanta

Move your diving skills up to the next level with the PADI Advanced Open Water Diver course. This great course not only certifies divers to depths of up to 30 meters, it’s also a fantastic opportunity to improve buoyancy, air consumption, and confidence in the water, leading to longer and more relaxed dives.

Koh Lanta Nitrox Course

Dive deeper for longer and feel less tired with your PADI Nitrox Certification. During your Open Water Diver course, you learned some of the limits of diving on normal air, and how nitrogen affects the body when we go scuba diving. During our dives, nitrogen is absorbed into our body tissues and this limits our diving depth and time. As you learned in your Open Water Course, too much Nitrogen can be a bad thing. Enriched Air gas mixtures contain more oxygen and less nitrogen which means that during a dive, our tissues are exposed to a lower partial pressure of nitrogen. This lower nitrogen partial pressure results in less nitrogen being absorbed by the body during a dive. During your course with us, you will normally be diving with 32% Enriched Air Nitrox, that is approximately 32% oxygen and 68% nitrogen. Many Nitrox divers also claim to feel much less tired after diving on Nitrox, and for those of you who are feeling a little less fit than you used to be, less nitrogen in your body can only be a good thing - especially if planning several days diving. The Nitrox theory typically takes 2 or 3 hours and is completed the day before your Nitrox dives. You'll also analyse your own tanks for 2 dives on 32% Nitrox. During your course, you'll also learn how to use a Nitrox diving computer, how to set and check the computer. If you don't have your own Nitrox dive computer, we'll give you one to use during the course for free.

Emergency First Response Course

A key part of being able to help other people, particularly with an adventure sport like scuba diving is being able to provide emergency first aid to an injured or sick person, and this is even more important when diving, often in remote areas with no emergency healthcare or hospitals close by. The Emergency First Response (EFR) course teaches both divers and non divers how to deal with life threatening problems and how to help maintain a person's life until professional medical help arrives.

Rescue Diver Course Koh Lanta

The PADI Rescue Diver course is both a challenging and rewarding courses which will change the way you look at diving forever. You will learn not only how to spot and deal with problems both underwater and on the surface calmly and with confidence, you will learn valuable self-rescue skills and develop a new sense of awareness of any potential problems with other divers around you. The PADI Rescue Diver Course is possibly the most rewarding course you will ever do. Save a life and change the way you look at diving forever. Diving, like any other adventure activity requires a great deal of attention to safety, and as you progress through the PADI courses from PADI Advanced Open Water Diver to PADI Rescue Diver, you will gain new skills which help you to deal with problems and help you to look after other divers.

Why Koh Lanta?

Scuba diving around Koh Lanta is relatively easy. Most dive sites are in the 5m - 25m depth range where we have the most sunlight, best colours and widest diversity of marine life on the coral reefs.

The dive sites, marine life and coral reefs are far more extensive, diverse and healthier in the Andaman Sea compared to the Gulf of Thailand. The perfect environment for teaching all PADI courses.

Visibility at Koh Lanta's dive sites is usually pretty good, often at least 5 - 15m around Koh Bida/Koh Phi Phi and usually more like 15 - 20m around Koh Haa for example. Sometimes visibility can be amazing, at certain times of year extending beyond 30 - 40m around Koh Haa.

The easy dive sites and good underwater conditions around Koh Lanta are fantastic for teaching scuba courses, from the beginner level PADI Open Water Diver, and PADI Advanced Open Water Diver, through to the more challenging Rescue Diver course.
