About this tour
When Ben from our team ran this speedboat snorkel tour from Koh Samui, we spent a full day hitting two islands — Koh Tao and Koh Nang Yuan — to hunt for coral, reef fish, and whatever else was lurking underwater. The vibe is pure tourist-friendly island hopping: you're on a fast boat with a mixed crowd, gear's provided, and the pace is gentle enough that swimmers of all levels can join in. It's nine hours door-to-door, with breakfast and lunch thrown in, and it's the kind of day trip that works if you want to tick off snorkelling without the faffing around.
Highlights
- Speedboat jumps straight into Koh Tao's underwater life
- Second snorkel site at Koh Nang Yuan with shore access
- Viewpoint hike option to break up water time
- White sand beach and downtime built into the day
- Snorkel gear sorted; no need to hire separately
- Light breakfast and lunch included in the package
- Air-con minibus takes pressure off the heat
- Flat entry water makes it approachable for varied swimmers
What to expect
Your day kicks off early — there's a pickup from your Samui hotel and an air-con drive to the speedboat pier. Once aboard, you're zipping across to Koh Tao for the first snorkel session. The boat crew sets you up, you plunge in, and there's decent coral and schooling fish to keep you occupied. It's not a guided deep-dive vibe; more like you're let loose in a designated spot and left to explore. After that, you head to Koh Nang Yuan, where you wade in from the beach instead. This one's shallower and a touch more leisurely — some people use the time to climb the island's viewpoint or just sprawl on the sand. Lunch happens somewhere in the middle, and the crew keeps things moving but not rushed.
What works: the two-location approach stops the day feeling repetitive, and the break for food and beach time is genuine downtime rather than a speed run. The underwater stuff is real — we saw plenty of colour and life — but it's not a pristine house reef either. Water clarity depends on the season and recent weather, so manage expectations if you're picturing gin-clear tropical footage.

Good to know
Dead straightforward for snorkellers of any level, and the kit's included so you're not renting halfway through the day. If you've got a weak stomach, having meals sorted means no hunting for food in dodgy floating vendors. The island time lets you stretch out between water sessions, and the viewpoint option at Koh Nang Yuan adds a mild adventure angle if you're not pure-water folk. Suits families with confident swimmers, solo travellers, and couples after a no-stress island day.
Koh Nang Yuan charges a separate entry fee (around 250 baht per adult), which isn't included, so budget for that. Beach loungers and brollies cost extra too. You'll be in a group, so don't expect intimacy — this is proper tourist-volume operation. The speedboat means early starts and potentially choppy rides if the sea's rough; not ideal if you're prone to motion sickness. The snorkelling is casual, not structured teaching, so absolute first-timers might feel a touch adrift. Not suitable if you have back problems, are pregnant, or have cardiovascular issues — the source flags these clearly.
Bring reef-safe sunscreen, a rash vest or light shirt, and a towel. The gear's included. Typically 20–40 people on the boat. Peak season (November–February) gets busier. Expect nine hours total; you're mostly in water or beach, so pace yourself.
