Why Koh Tao is Perfect for Scuba Diving for Kids
Calm, Warm Waters
Year-round water temperatures of 26-30°C provide comfortable conditions for young divers without thick wetsuits.
Abundant Marine Life
Colorful fish, sea turtles, and coral reefs create exciting underwater experiences that captivate young minds.
Experienced Instructors
Koh Tao’s dive centers employ instructors specifically trained in teaching children and family groups.
Shallow Dive Sites
Multiple sites under 10 meters depth provide perfect training grounds for young divers.
Safety Infrastructure
Medical facilities, hyperbaric chamber access, and established emergency protocols ensure safety.
Family-Friendly Environment
Many dive centers offer family packages and activities for non-diving family members.
Year-Round Diving Season
Koh Tao’s warm tropical climate allows children to learn scuba diving throughout the year, with generally calm conditions.
Excellent Underwater Visibility
Visibility often ranges from 10 to 30 meters, making it easier for children to see their instructor, marine life, and dive equipment underwater.
Best Kid-Friendly Dive Sites in Koh Tao
Koh Tao’s most popular training and family sites are shallow, sheltered, and rich with marine life, making them ideal conditions for young divers. Here are the best shallow dive sites in Koh Tao for beginners:
1. Mango Bay
A sheltered bay on the north coast with a sandy bottom and coral gardens on both sides. Depths range from roughly 2 to 15 meters. It is one of the calmest and most beginner-friendly bays on the island, home to giant clams and barrel sponges.
2. Japanese Gardens
A shallow coral cove near Koh Nang Yuan with depths rarely exceeding 12 meters and minimal current. It is known for its variety of hard and soft corals, sea turtles, and clownfish, making it a favorite for first open water dives.
3. Twins
Two shallow pinnacles around 12 meters deep, home to a resident clownfish (“Nemo”) family, moray eels, and stingrays. It is a classic training site that is calm enough for young divers while remaining interesting enough to hold their attention.
4. Aow Leuk
A sheltered bay on the southeast coast with a gentle sloping bottom, coral bommies, and frequent sightings of butterflyfish and juvenile blacktip reef sharks.
Best Time of Year for Family Diving in Koh Tao
Koh Tao is diveable year-round, but conditions vary:
- December to May (dry season): The calmest and clearest time of year, and generally the most comfortable for first-time and young divers. Gentle currents, warm water, and stable weather make it easier to build confidence early.
- June to September: Winds pick up, so instructors often shift to the sheltered east coast sites during this period. The island is still very diveable, but conditions require more day-to-day adjustment.
- October to November: Koh Tao’s rainiest period, with more variable diving conditions.
Every season offers a different diving experience; it is important to learn in detail about the best time to dive in Koh Tao before you go with your kids for diving.

Frequently Asked Questions
What makes scuba diving for kids Koh Tao different from other destinations?
Scuba diving for kids Koh Tao stands out due to consistently warm water temperatures (26-30°C), calm conditions, shallow training sites, and dive centers with extensive experience teaching children. The island’s compact size and family-friendly infrastructure make it ideal for young divers.
What’s the youngest age for scuba diving for kids Koh Tao programs?
Children can start with Try Dive experiences at age 8. These introductory programs are conducted in shallow, controlled environments with maximum depths of 2 meters, providing a safe first taste of underwater breathing and movement.
Do kids need to be strong swimmers to learn scuba diving?
While advanced swimming skills aren’t required for introductory programs, children should be comfortable in water and able to float or swim short distances without assistance. Basic water confidence is more important than swimming speed or technique.
How do La Bombona’s instructors ensure child safety during diving?
La Bombona maintains strict 1:2 instructor-to-student ratios for children, uses age-appropriate equipment, conducts thorough skill assessments before advancing, and follows conservative depth limits. All instructors receive specialized training for teaching young divers.
Can parents dive with their children during courses?
Parents with diving certification can often participate in family dives, but children’s training dives are typically conducted with professional instructors to ensure proper skill development. Family fun dives can be arranged after course completion.
What happens if a child feels scared or uncomfortable underwater?
Instructors are trained to recognize signs of discomfort and will immediately surface with scared children. No pressure is applied to continue if a child feels uncomfortable. The goal is building confidence gradually through positive experiences.
Are there medical restrictions for children learning to dive?
Children with asthma, ear problems, heart conditions, or other significant health issues require medical clearance before diving. A standard medical questionnaire must be completed, and some conditions may require doctor approval before participation.
What is the "120 rule" in diving?
The “Rule of 120” isn’t a children’s diving guideline. It is an older general dive planning shortcut where depth in feet plus no-decompression time in minutes equals approximately 120, based on outdated US Navy dive tables. Modern dive computers and agency tables have replaced it. It has no direct application to kids’ shallow, depth-limited programs like Bubblemaker or Junior Open Water, which use their own fixed depth limits.
Who is not allowed to scuba dive?
Anyone with uncontrolled asthma, certain heart or lung conditions, or other significant unresolved health issues typically needs medical clearance before diving. For children specifically, this is why La Bombona requires a completed medical questionnaire before any first dive.
What is the minimum age for scuba diving in Koh Tao?
The minimum age is 8 years old for introductory programs like Bubblemaker (pool or confined water only, maximum depth of 2 meters). Full Junior Open Water certification, which allows ocean diving to 12 meters, starts at age 10.
Can beginners learn scuba diving as a family in Koh Tao?
Yes. Koh Tao’s calm, shallow bays and warm water (26–30°C year-round) make it one of the world’s most popular places to learn as a family. Children as young as 8 can join introductory programs while parents or older siblings pursue Open Water certification alongside them. Many dive centers also offer family-friendly boat facilities for non-diving family members.
What safety measures are followed for kids' scuba diving?
Kids’ scuba diving programs follow strict safety standards, including:
- Low instructor-to-student ratios (typically 1:1 or 1:2) for close supervision.
- A gradual introduction to diving, starting in shallow water before progressing to deeper dives.
- Child-sized scuba equipment that is properly fitted for comfort and safety.
- Medical clearance for children with asthma, ear problems, heart conditions, or other health concerns.
- A buddy system with certified adult supervision where required.
- Continuous skill and comfort assessments before moving to greater depths or open-water dives.
What should children bring for a scuba diving trip in Koh Tao?
For the diving day itself, children should bring a swimsuit (worn under the wetsuit), a towel, reef-safe sunscreen, a hat, water shoes or sandals, a change of dry clothes, and any completed medical clearance paperwork if required. For everything else you’ll need for the wider trip, see our full Koh Tao packing checklist.
How long does a kids' scuba diving session last?
A Try Dive or Bubblemaker session is typically run as a full-day experience, though actual time breathing underwater is short and closely supervised. The Junior Open Water course runs over 4 days with 4 ocean dives, each dive typically lasting 30–45 minutes depending on air consumption and conditions.
What is the difference between Bubblemaker and Discover Scuba Diving for kids?
Bubblemaker (age 8+) takes place in a pool or confined water only, with a 2-meter depth limit and no certification issued. Discover Scuba Diving (age 10+) can take place in open water, either in a sheltered bay or from a boat, and is also non-certifying. Many dive centers apply its cost toward a full Open Water course if a child continues.
Are private family scuba diving tours available in Koh Tao?
Family and private group sessions can typically be arranged on request. It’s worth confirming directly with your dive center whether a fully private (just your family) booking is available or whether you’ll join a small mixed group, as this varies by season and availability.
