About this tour
When Ben from our team tried this Koh Chang scuba day out, we hit the water for two solid dives across eight hours. The operator runs two main routes depending on conditions: a dive on Thailand's largest shipwreck (the HTMS Chang) plus coral sites, or the mellower option of two shallow coral dives in Koh Rang National Park. Either way, you're with a pro guide, kit's sorted, and lunch shows up on the boat. The vibe is mixed — some days you'll spot serious divers keen for the wreck challenge, other days it's more relaxed coral pottering. What matters: you need proof of dive cert to join, and the operator's flexible about routing based on weather and what you're after.
Highlights
- Thailand's largest shipwreck dive — genuinely dramatic site for certified divers
- Two coral reef options mean flexibility if conditions aren't wreck-friendly that day
- Hotel pickup and drop-off saves the faff of getting to the boat
- Lunch and drinks on board — no surprises or hunger mid-day
- Shallow Koh Rang dives suit steady swimmers after a break from diving
- Option to add a third dive for 1000 baht if you're keen for more
- Operator asks your prefs upfront — not a rigid cookie-cutter route
What to expect
You'll get picked up from your hotel in the early morning, then head to the boat. Ben's experience was straightforward: brief check-in, gear fitting, safety rundown, then into the water for dive one. If the HTMS Chang is on the plan that day, expect to descend into a proper wreck — lots to see, takes focus. If it's National Park coral instead, the vibe is gentler, shallower, and packed with fish and anemones. Surface interval mid-morning means a rest, snacks, and a chat with your guide before dive two. Lunch (usually rice and curry) shows up on deck. The whole thing feels unrushed, though eight hours on a boat in tropical heat isn't everyone's jam. Weather can shift the plan — guides know the sites and swap routes if conditions turn dodgy.

Good to know
The outfit genuinely tailors the day to conditions and your vibe. Wreck diving is a proper draw for cert-holders; if that's sold out or choppy, coral dives are a solid fallback and less mentally taxing. Full kit hire means you don't lug gear from Australia. Lunch and drinks included cut down on nickle-and-diming. Pickup from your hotel is a timesaver, especially if you're not staying near the pier.
You must carry proof of dive certification — lapsed or rusty? You won't go. National park fees are extra and aren't flagged in the headline price. Pregnant travellers and anyone with cardiovascular worries shouldn't book — medical screening isn't thorough, so read the health notes carefully. Eight hours on a boat can feel long if you're prone to seasickness; bring meds. Peak season (Nov–Mar) crowds up the boats. Third dives cost extra (1000 baht). Wheelchair-accessible means the boat meet point; getting on the boat itself may be tricky depending on the vessel.
Bring reef-safe sunscreen, a light rash guard, and anti-nausea tablets if you're prone. The package includes all kit and refreshments. Group sizes vary. Best booked in advance, especially high season.
