Koh Tao Diving Price at a Glance

Prices below combine the published list of Koh Tao Divers with ranges quoted by other island schools. Treat them as indicative, because each school sets its own rates. Prices checked November 2026.

What Affects the Price of Diving on Koh Tao

Group size is the biggest lever. Koh Tao Divers caps its groups at 4 divers, and smaller groups usually cost more to run. Agency matters less than people expect. PADI, SSI and RAID Open Water courses are generally priced in the same ฿9,000–11,000 band, and the school drives most of the gap. Course length also shifts the total. Open Water takes 3 days at Koh Tao Divers and 3.5 or 4 days at other schools. Bundled beds, e-learning, boat versus shore diving and photo packages add further variation.

Try Dive vs Open Water vs Advanced: Which Fits Your Time and Budget

A Try Dive suits one free day and no certificate. Koh Tao Divers lists it at ฿3,800 for 2 dives. If you love it, upgrading to Open Water costs ฿8,100 more, which brings the total to ฿11,900. Ask any school whether your Try Dive credits toward certification, since terms differ. Open Water certifies you to 18 m, and the SSI Open Water program sets out the structure. Advanced adds depth and variety in 2 days and 5 dives for ฿10,900 at Koh Tao Divers. Choose Try Dive for one day, Open Water for 3–4 days, and Advanced if you are already certified.

• One day free: Try Dive, about ฿2,500–3,800
• Three to four days: Open Water, ฿9,000–11,900
• Already certified, two days: Advanced, ฿8,500–10,900

Fun Dive Prices and Packages

Certified divers pay about ฿800–1,000 per fun dive. Multi-dive packages and bundled courses usually lower the per-dive rate, so ask for a package quote before booking singles. Advanced courses include night and deep dives, which is where many divers first see sites like those in our night diving guide. Our overview of Koh Tao Marine Life: What You'll See, Where and When shows what those dives can turn up.

What's Included and What Costs Extra

Course packages normally include gear, instructor fees and boat trips. Extras add up, so ask for a written list. One school charges a mandatory ฿100 insurance fee. Koh Tao has no marine park fee, according to the same school.

• Included: rental gear, instructor, boat dives in course packages
• Extra: optional second Try Dive dive, ฿1,000 at one school
• Extra: underwater photo and video packages, sold on the final day
• Extra: tips for boat crew and instructors
• Extra: ferry, bed and food, covered in the trip budget below

Gear: Rent, Buy or Bring

First-timers rent everything, and course packages cover it. Occasional divers can buy their own mask and fins for roughly ฿1,000–3,000, which improves comfort on repeat dives. Regular divers may add a dive computer, with entry models from about 150–200 USD. Wetsuit thickness depends on conditions, so check Koh Tao Water Temperature by Month: What to Wear Diving before buying anything.

Cheap vs Good Value: How to Compare Dive Schools

A ฿1,000 saving disappears fast if the group is large or the gear is tired. Compare these points in writing before you pay. If you are still weighing the island itself, read whether Koh Tao suits divers.

• Instructor-to-student ratio and group cap
• Boat capacity and gear age
• Briefing language
• Accident and chamber cover
• Cancellation and no-show terms
• Pricing mistake: comparing a 3-day course with a 4-day one
• Pricing mistake: forgetting insurance, photos and tips
• Pricing mistake: booking the cheapest quote with no group cap

Season and Price: When Diving Costs Less

One school's guide says December to March beds cost 50–100% more. It puts October–November and late January–February 30–50% cheaper, with beds from ฿300 a night. Koh Tao Divers describes October and November as monsoon months with heavier rain and rougher seas. These accounts conflict, so weigh savings against sea conditions. Our best time to dive page covers the trade-off. The Thai Meteorological Department publishes forecasts.

Total Trip Budget: Sample Scenarios

These totals are illustrative. They add course fees to beds at the ฿300 minimum, and leave out ferry, food, tips and insurance because those costs vary. Stay-and-dive bundles are covered in our dive resort guide.

Booking, Cancellation and Flying Rules

Koh Tao Divers asks you to confirm availability first, then pay a deposit and settle the balance at sign-up. It allows free rescheduling with 24 hours' notice. A no-show within 24 hours is charged in full. Wait 18–24 hours after your last dive before flying. Divers Alert Network publishes flying-after-diving guidance. Basic school cover at Koh Tao Divers lasts 30 days, pays up to ฿500,000 in medical costs including chamber treatment, and excludes evacuation. Patients pay upfront. Dive Assure plans start from €70 a year for most EU citizens. Read our hyperbaric chamber guide before choosing cover.

Where to Save Money, and What Is Worth Paying For

Save by bundling Open Water with Advanced, renting gear and traveling in shoulder months. Pay for small groups, sound gear and proper insurance. Skip liveaboard planning until you are certified, then see the liveaboard guide. Comparing islands? Our Koh Tao and Koh Phangan comparison helps.
