About this tour
When Charlie from our team ran this snorkeling tour out of Koh Tao, we hit five different bays across a 6–7 hour day on a decent-sized boat with proper facilities. The route takes in Shark Bay (where blacktip sharks actually show up), Leuk Bay, Hin Wong, Mango Bay, and the standout climb up Koh Nang Yuan's viewpoint — all anchored by a buffet lunch aboard and swimming among healthy coral and tropical fish. It's a solid island-hopper if you want to see multiple spots without renting your own boat, and the vibe stays fairly relaxed because the crowds thin once you're on the water.
Highlights
- Blacktip sharks at Shark Bay — real sightings, not a guarantee but genuine.
- Koh Nang Yuan viewpoint hike rewards you with proper panoramic island views.
- Five separate snorkeling drops mean coral variety and better fish encounters.
- Lunch on board (buffet style) saves you hunting for food mid-tour.
- Large boat with toilet facilities — no squatting ashore between stops.
- Morning snacks and fruit beverages keep energy up without extra cost.
- Hotel pickup/drop within Koh Tao removes the hassle of getting to port.
- English-speaking guide handles safety briefing and spot history clearly.
What to expect
You'll start with hotel collection (unless you're staying far north), then board a spacious catamaran-style vessel with other tourists — expect 20–40 people on most days. The boat runs a circuit: first bay typically within 30 mins, then 45–60 mins snorkeling per stop with a guide briefing and 10–15 min surface intervals between dives. Water clarity varies seasonally, but we saw healthy corals and schools of jacks and snapper most dives. The Koh Nang Yuan climb takes about 15 mins up and is steep-ish but short; the viewpoint payoff is genuine. Lunch happens mid-tour aboard (buffet curries, rice, veg — nothing fancy but hot and filling). Afternoon slots tend quieter than morning ones; peak season (Nov–Feb) can feel crowded at anchor, but water time itself stays manageable because not everyone gets in simultaneously.
Weather is the wild card: rough seas flatten some bays, and the boat skips stops if conditions turn. We experienced one reschedule due to swell; the operator offered an alternative date without fuss. Pacing is leisurely rather than rushed, which suits mixed-ability groups.

Good to know
Real value if you're based on Koh Tao and want to sample multiple reefs without chartering privately. The shark bay is a genuine draw (blacktips are common, harmless, and a proper moment). Snorkeling gear is included — no surprise rental fees — though they don't provide fins, so bring your own or hire on arrival (often 100–200 THB locally). Buffet lunch and fruit breaks keep you fuelled. Hotel transfers within town are genuinely convenient. Insurance is baked in. Works for kids aged 7+ and all fitness levels, though the Koh Nang Yuan climb will test anyone with knee or ankle issues.
National Park fee (250 THB adult, 150 THB child) is a sneaky extra not in the advertised price. Early start (usually 8–9 a.m.) means an alarm if you're sleeping in. The boat holds 40–50 people, so don't expect an intimate group — you'll share anchor points. Not suitable if you're pregnant, have spinal injuries, heart issues, or high blood pressure (rules are strict for liability). Mango Bay stop doesn't include return transfer, which is odd. Fins aren't provided, so budget for hire or BYOD. Sea state can cancel or reroute the tour with minimal notice. Peak season sees busier departures.
