About this tour
When Em from our team did the PADI Open Water Diver Course in Thailand, she went from zero diving experience to certified in three days flat. Day one's all theory and pool work in shallow water; days two and three ship you out to Koh Chang and Koh Rang National Park for four proper open water dives at coral reefs. Small groups mean you're not herded around like a school group, and the outfit throws in kit, transfers from your hotel, meals, and drinks. By the end you're signed off to dive to 18 metres anywhere on the planet.
Highlights
- Pool training first — no sink-or-swim approach here
- Four reef dives over two days with real marine life
- All gear provided, no expensive rental surprises
- Hotel pickup and lunch included in the package
- Koh Rang National Park backdrop is genuinely stunning
- Small groups mean guides actually know your name
- Worldwide certification — not just a local piece of paper
What to expect
Day one is classroom and pool — you'll learn the theory, practice basic skills like clearing your mask underwater, and build confidence in shallow water before anything serious happens. Em reckoned it felt thorough without being rushed. Days two and three, you're on a boat heading out to the reefs. The guides take you down in pairs or small groups, walking you through skills on the reef floor itself, then letting you explore once they're confident you've got it. The coral and fish life around Koh Chang and Koh Rang is genuinely colourful — not Caribbean-level dramatic, but enough to keep your eyes busy. The pace is steady rather than frantic, which matters when you're learning to breathe underwater for the first time.
Weather is the wildcard — Thailand's tropical, so rough seas can shut things down. The outfit offers alternative dates or refunds if conditions tank. Most people find three days doable without being wrecked, though Em flagged that the early boat times and full days of concentration take it out of you.

Good to know
If you're keen to dive but intimidated by the prospect, this is properly structured. You're not chucked in the deep end (literally) — progression is logical. Small groups genuinely make a difference; Em's guide caught when her buoyancy was off and fixed it before it became a problem. Everything's included except the national park entrance fee, so no hidden costs for kit hire or transfers. The certification is PADI-standard, so it works globally.
Three days is intense if you're not used to early starts and concentration underwater. Weather delays happen — keep flexible dates if you can. The early-morning boat departure isn't negotiable, so night owls will struggle. Transfers are only from West coast hotels on Koh Chang, so check your location. You need to fly in at least 18 hours before diving (nitrogen in your blood), and a bunch of health conditions rule you out — asthma, heart stuff, pregnancy. Fill out the health form honestly; guides won't let you go if something's dodgy. Not one for little kids.
Bring a swimsuit, towel, and sun protection. The course is three solid days. Best times are November to February (dry season); avoid May to October if you can.
