About this tour
When Em from our team took this speed boat jaunt from Koh Samui, we hit Koh Tao and Koh Nang Yuan for a solid 8-hour snorkeling mission. Koh Tao (Turtle Island) lives up to its rep — the Gulf's clearest water, vibrant reefs, and fish life that actually justify the hype. Koh Nang Yuan is the scenic bonus: three islets joined by sand, brilliant for a beach lunch and afternoon explore. The speed boat cuts travel time and keeps the day zippy. It's a straightforward, well-worn route that works because it delivers what it promises: good visibility, decent coral, and enough downtime to actually enjoy yourself without feeling rushed.
Highlights
- Koh Tao's visibility genuinely stands out — coral detail visible beyond typical snorkel depth
- Koh Nang Yuan's three-island setup and white-sand connector beach are visually striking
- Lunch beachside with uncluttered ocean views — beats eating on a boat
- Speed boat shaves hours off travel compared to standard ferry pace
- Snorkel gear provided; no rental hunt or extra cost on the day
- Afternoon window to trek the viewpoint or laze between swims
- Mix of reef and sandy-bottom sites suits varying snorkel confidence levels
- Round-trip transfer from Koh Samui removes the logistical friction
What to expect
You'll depart Koh Samui early and cross to Koh Tao in about 90 minutes by speed boat — quicker than a standard ferry but you do feel every wave. First stop is the main snorkel site off Koh Tao where the water clarity is genuinely impressive; reefs are busy with fish and the seabed is visible even from the surface. You get a solid couple of hours in the water here, which is enough to explore without overthinking it.
After Koh Tao, the boat motors to Koh Nang Yuan where lunch happens on the beach (buffet spread, soft drinks included). The afternoon is yours — snorkel the shallows around the connected islands, swim, or hike the short trek to a viewpoint overlooking the three-island cluster. It's relaxed pacing; no herding or tight schedules. The boat ride home is gentler, and you're back on Samui by late afternoon. Fair warning: the speed boat does pitch in any chop, and the day hinges on decent weather; rough seas can shift the itinerary.

Good to know
The clarity at Koh Tao is legitimate — worth the trip if you've done murkier reefs elsewhere. Koh Nang Yuan's scenery is genuinely photogenic, and the afternoon beach time breaks up the day nicely. Snorkel kit is sorted, lunch is included, and transfers from your Samui hotel save logistical hassle. Suits anyone comfortable in water; no extreme fitness needed, though a basic level of swimming confidence helps.
Entrance fees (250 baht adult at Koh Nang Yuan, 80 at Koh Raham if weather allows) aren't included — budget an extra 330 baht or so per person. Beach loungers and umbrellas at Koh Nang Yuan cost extra, so bring a hat or embrace the shade shuffle. The speed boat can be rough if seas are choppy; not ideal for anyone prone to motion sickness or with back issues. Early start required (typical pickup 7–8 a.m.). Groups are mixed nationality and size — expect company. Not recommended if pregnant, recovering from spinal injury, or dealing with cardiovascular concerns. Peak season (Nov–Mar) draws crowds; consider shoulder months for fewer bodies in the water.
