About this tour
When Jake from our BugBitten team ran this day trip from Samui, we jumped on a speedboat and hit two islands in one hit. Koh Tao's Mango Bay gave us proper snorkelling time in clear water, followed by lunch on the island itself. Then it was across to Koh Nang Yuan — the smaller, quieter sibling — where you can swim, snorkel again, or hike up for views across the gulf. It's a solid full-day loop: van pickup, boat, two islands, food sorted, back by evening. The crowd varies depending on season, but it feels purposeful rather than rushed.
Highlights
- Clear waters at Mango Bay packed with actual fish and coral
- Lunch cooked on Koh Tao, not pre-made plastic container job
- Full hour to swim and snorkel without being herded on
- Koh Nang Yuan's mountain hike rewards with genuine vista
- Speedboat itself is nimble and genuinely quick between islands
- Snorkelling gear provided, no surprise rental costs
- Small enough groups to not feel factory-conveyor touristy
- Soft drinks on board beats paying triple-markup island prices
What to expect
You'll be picked up from your Samui hotel in a van and driven to the pier — pretty standard stuff, air-con works. Once on the speedboat, it's maybe 20–30 minutes to Koh Tao. Mango Bay (Ao Muang) is where the real day starts: you get a full hour in the water. Some of our team snorkelled, others just floated and read. The water's genuinely clear, and you'll see wrasse, parrotfish, small reef stuff — nothing dramatic, but honest snorkelling. Around noon you eat on the island itself, which breaks up the day nicely and tastes better than you'd expect.
After lunch, it's another short boat ride to Koh Nang Yuan. This island is smaller and feels less commercialised than Tao. You can swim, snorkel the same waters, or tackle the hike up the middle — Jake did the hike and reckoned the 20-minute climb and the view were worth the sweat. The whole operation wraps by late afternoon, and you're back on Samui by early evening. Weather and tides can shift things around, so don't plan anything tight afterwards.

Good to know
If you're based in Samui and want to see two islands without booking separate trips, this stacks them efficiently. The snorkelling is genuine — not a marketing angle. Lunch and soft drinks included save you blowing money at island cafés. Small-group vibe means your guide remembers you, not just a face in a crocodile. The hike option on Nang Yuan is legit for anyone wanting something beyond floating.
Weather and tides run the show — your itinerary can shuffle. National park fees (THB 250 per adult) aren't included, so budget that separately. The boat ride suits most people, but if you've got spinal issues, pregnancy, or dodgy cardiovascular health, this isn't the tour. Early-ish start (no exact time given, but typical is 7–8am) and eight-plus hours out means late lunchers will struggle. Bring proper trekking shoes if the hike appeals — flip-flops will do you in. Sunscreen is essential; the sun on water is ruthless.
Pack towel, swimwear, sunscreen, hat, sunglasses, flip-flops, trekking shoes, camera. Snorkelling mask provided. Van pickup from your Samui hotel included. Lunch and drinks on board included. Group size typically 15–25 people. Peak season (Nov–Feb) gets busier; shoulder months are quieter.
