About this tour
When Sarah from our team ran this snorkeling tour out of Koh Tao, we spent 6–7 hours island-hopping to spots like Shark Bay, Ao Leuk, and the postcard-famous Koh Nang Yuan. The boat's got the toys — water slide, climbing wall, diving board — and the crew knows the reefs. You'll see healthy coral, schools of tropical fish, and clear water. It's busy but well-organised, with lunch and kit included, and feels like the kind of outing that hooks both first-timers and seasoned snorkellers. The island itself is low-key, backpacker-friendly, and draws a mix of ages and nationalities.
Highlights
- Shark Bay and Ao Hin Wong reefs teemed with wrasse and parrotfish.
- Koh Nang Yuan viewpoint hike rewards with three-curved-beach vista.
- Onboard water slide and diving board beat sitting still.
- Lunch and cold drinks kept us fuelled between snorkel spots.
- Boat had air-con cabin and roof terrace to escape sun.
- All snorkel gear and life jackets provided; no rental faffing.
- Hotel pick-up and drop-off saved us the tuk-tuk hunt.
- Guide navigated currents well; felt safe the whole time.
What to expect
You'll be collected from your resort and ferried out early, joining a boat of around 15–20 mixed-nationality snorkellers. The first stop is typically a shallower bay where the guide does a quick safety brief and gear check — masks get sorted fast. You'll snorkel three or four sites over the morning and early afternoon, with 20–30 minutes in the water at each spot. The pace feels unhurried; no one's rushing you up. Around midday, lunch arrives on deck — simple but solid — and there's time to dry off and chat. The boat rocks gently between sites, and the air-con cabin is a godsend if the heat gets heavy. The highlight is usually Koh Nang Yuan, where you'll climb about 15 minutes uphill to a viewpoint that genuinely justifies the Instagram hype. By late afternoon, you're back on the beach.
What surprised us: the reefs are patchy in spots. You'll see good coral and fish, but it's not a pristine lagoon — the island gets a lot of traffic. That said, the guides know where the shy species hide, and the water clarity on calm days is genuinely lovely. The boat's designed for fun rather than serious diving, so expect a social vibe and some noise.

Good to know
This works for mixed abilities, from non-swimmers (shallow spots available) to confident snorkellers keen to roam further. The inclusions are generous — lunch, drinks, all kit, and transfers — so your only out-of-pocket is the 250 baht national park fee per adult. The boat has real amenities (toilet, air-con, music), which sounds silly until you're six hours on the water. Small groups feel personal without being lonely.
You need a minimum of 10 people or the tour may cancel (they'll rebook or refund). Pregnant guests, anyone with heart or bone conditions, or spinal injuries shouldn't go — the boat's movement and snorkelling pose genuine risk. The reefs aren't pristine, so expect moderate crowds and some seaweed. It's not a quiet experience; the water slide and music keep things lively, which some find fun and others find a bit much. The national park fee isn't included, which catches people off guard.
Wear reef-safe sunscreen or a rash vest; the sun's relentless. Bring a light towel and a dry shirt for the boat. Seasickness pills aren't a bad idea if you're prone. The tour includes all snorkel gear, life jackets, lunch, and hotel transfer (except from Mango Bay and Lighthouse Beach). Trips run daily, so booking the night before is usually fine.
