About this tour
When Alex from our team took this speed boat snorkel tour from Samui, we were heading out to Koh Tao and Koh Nang Yuan — two islands that genuinely live up to the hype for clear water and coral. The 9-hour loop includes a proper hike up to Nag Yuan viewpoint (one of Thailand's best vistas), time exploring the reefs around Koh Tao, and lunch on the beach. It's a full-on day that pulls you well away from the Samui tourist drag, and you're sharing the boat with other travellers rather than going private. Light breakfast at the pier gets you started early, and the outfit handles hotel pickups with air-con cars.
Highlights
- Speed boat cuts travel time — you're snorkeling within an hour or two
- Nag Yuan viewpoint hike pays off with genuinely stunning panoramic shots
- Coral reefs around Koh Tao host colourful fish and reasonable turtle spotting odds
- Thai buffet lunch beats the usual tour-group sandwich fare
- English-speaking guide handles safety and points out reef creatures
- Equipment, life jacket, and insurance all sorted — no extra hassles
- Share-transfer model keeps costs down versus private alternatives
What to expect
You'll get picked up from your hotel early, reach the pier for a quick breakfast, then board a decent-sized speed boat with maybe 20–30 other travellers. The ride to Koh Nang Yuan takes roughly an hour and it can be choppy if the ocean's up. Once there, you'll snorkel the shallower reefs around the islands — the water is genuinely clear and fish are plentiful, though sea creatures aren't guaranteed. The hike to Nag Yuan viewpoint is short but steep in the tropical sun; most people manage it fine, and the view really is the postcard version of Thailand.
After the viewpoint, you'll head to Koh Tao for more snorkeling and lunch at a beachside restaurant. The food is hearty Thai buffet — nothing fancy, but filling. You'll have time to swim and rest before the boat heads back. The whole day feels active rather than rushed, and the guide keeps an eye on snorkelers. Weather and sea state can shift the schedule slightly, and the shared boat means you're with strangers — some fun, some quiet.

Good to know
This tour genuinely gets you to two of the region's best islands without a hefty price tag. The snorkeling is solid for Southeast Asia standards, the viewpoint hike is a real highlight, and lunch at the beach beats generic tour food. You'll see a mix of families, couples, and solo travellers. It's suitable for most fitness levels, though the hike has steps and sun exposure.
The 9-hour day means an early start, and sea conditions can make the boat ride uncomfortable for anyone prone to motion sickness. The shared transfer model means you might wait for other hotel pickups. Island entrance fees (250 Baht for adults, 125 for kids) are not included and payable on arrival. The tour isn't suitable if you're pregnant, have spinal issues, or poor cardiovascular health. Infants must sit on an adult's lap, which isn't ideal on a bouncy boat. Peak season (Dec–Feb) gets busy.
Bring sunscreen, a light cover-up, and motion sickness tablets if you're prone. Included: water, snorkel gear, life jacket, breakfast, lunch, and hotel transfer. Not included: entrance fees and any extra drinks or snacks. Groups typically run 20–30 people. Book a day or two ahead.
