About this tour
When Em from our team booked Mr. Tu's speed boat snorkel day from Koh Samui, we got a full eight-hour loop hitting Koh Nangyuan and Koh Tao's quieter eastern bays. The vibe is mixed-nationality groups (guides speak English and Mandarin) heading out early to beat the afternoon crowds on the reefs. You're looking at decent snorkeling spots—the Japanese Reef Garden lives up to its name—plus a couple of beach stops and a proper Thai lunch onboard. It's the kind of tour that works best if you're after a straightforward island day without pretence: get wet, eat, get back by late afternoon.
Highlights
- Japanese Reef Garden snorkel site genuinely delivers colourful coral and fish
- Speed boat ride itself feels quick and purposeful, not leisurely
- Koh Nangyuan viewpoint offers postcard-worthy panorama of three islets
- Thai buffet lunch onboard beats most beachside tourist fare
- Hotel pickup included saves faffing with transport logistics
- Quieter eastern bays of Koh Tao less rammed than main beach zones
- Small-group feel means guides actually notice who's struggling
What to expect
You'll be picked up from your Koh Samui hotel in the pre-dawn dark—expect a 6 a.m. start or thereabouts. The speed boat ride to Koh Nangyuan takes under an hour; it's bumpy if the sea's up, smooth if it's not. First stop is the viewpoint (entrance fee your shout), then into the water for the reef garden swim. By mid-morning you'll dock for a break, then head to Koh Tao's eastern side where the cliffs rise steeply and the water stays clearer than the west-facing beaches. Lunch is served onboard—think rice, curries, fresh fruit—and reasonably tasty. The second half of the day is more snorkeling and beach time before the ride home. Most of the day is in the water or on a boat, so pace is brisk rather than lazy.

Good to know
This works well if you want to tick two islands in one day without renting your own boat. The snorkeling gear is included and serviceable, and the professional guides (English and Mandarin speakers) actually know the reefs. Hotel transfers save you navigating Koh Samui's chaotic taxi scene. Lunch is proper Thai food, not cheese sandwiches.
Koh Nangyuan entrance fees aren't included—budget an extra 100 baht or so. The early start rules out sleeping in. Sea conditions in the gulf can be choppy, so it's rough on sensitive stomachs and not suitable for pregnant travellers or anyone with serious back or heart issues. Eight hours on a speed boat means you'll be damp and salty by the end. Peak season (December–February) gets busy; shoulder months feel less cramped. Not accessible for cruise passengers due to time constraints. Bring reef-safe sunscreen and a rash guard if you burn easily.
