About this tour
When Charlie from our team ran this full-day snorkel tour from Koh Samui, we shot across to Koh Tao and Koh Nang Yuan by speedboat—two islands that genuinely deliver on the underwater front. You're talking vibrant reefs, schools of tropical fish, and the chance to climb Nang Yuan's viewpoint for proper island views. The tour hits multiple snorkel spots, feeds you a local lunch, and bundles in gear and an English-speaking guide. It's 9.5 hours door-to-door, and the boat ride itself is part of the charm: proper tropical theatre getting there and back.
Highlights
- Speedboat crossing feels quick, gets you out to the islands fast
- Multiple snorkel sites mean variety—coral gardens and fish abundance
- Koh Nang Yuan's three-island sandbar and clifftop viewpoint genuinely stunning
- Local lunch included beats grabbing food on your own
- Professional gear and English-speaking guide takes stress out
- Suitable for swimmers of any ability—reefs are accessible
- Quiet enough to spot turtles if you're lucky
What to expect
You'll get picked up from your Samui beach resort in the morning and driven to the pier—timing varies, but they confirm the night before. The speedboat ride out is exhilarating and takes maybe 45 minutes. First stop is Koh Tao, where you'll spend a couple of hours in the water with the guide pointing out coral and fish. The reefs are genuinely colourful, and even modest swimmers can stay comfortable in the shallows.
You'll move to Koh Nang Yuan mid-morning for snorkelling again, then get time to climb to the viewpoint—the path is steep but only takes 15 minutes, and the views across three islands connected by sandbars are worth it. Lunch happens at a casual beachside spot, nothing fancy but filling. The afternoon brings a final snorkel session before the boat heads back. Expect to be tired but not wrecked—it's full-on but paced reasonably.

Good to know
This is a solid, no-fuss way to see two of Thailand's best snorkel sites in one day. The reefs are properly alive, and the mix of water time and island exploration keeps it interesting. If you're a decent swimmer or even novice, you'll be fine—guides are attentive and reefs are close to shore. The speedboat adds a bit of adventure to the journey itself, and lunch keeps you fuelled without blowing your budget.
The pace is brisk, so if you're after a leisurely day, this isn't it. Koh Tao charges a 300 baht entrance fee you pay in cash on arrival—easy but easy to forget. The boat can get bouncy in choppy seas. You'll need to bring cash for this (no ATMs on the islands, no card machines), and sunburn is real—the sun reflects hard off water and sand. Early-ish start, so not for night owls. Pickup applies only to main Samui beaches; if you're elsewhere, expect extra charges or to meet at a hotel.
Bring sunscreen, hat, sunglasses, and a dry bag for your phone and camera. Snorkel gear is provided. Lunch is included, but any extras or drinks beyond what's given are on you. Minimum two people to book. Not suitable for wheelchair users. Don't expect to confirm exact pickup time more than a day ahead.
