About this tour
When Jake from our BugBitten team took this full-day island cruise from Koh Samui, he hopped between Koh Nang Yuan and Koh Tao — two islands renowned for snorkelling and marine life. The day runs 7–8 hours and centres on exploring coral gardens, spotting tropical fish, and if you're patient, sea turtles. You'll also hike to a viewpoint for views across the archipelago. Breakfast and a Thai buffet lunch are included, along with gear and hotel transfers from most Samui beaches. It's a solid option for swimmers and snorkellers who want to venture beyond the resort.
Highlights
- Two islands in one day — Koh Nang Yuan's coral gardens and Koh Tao's marine biodiversity covered
- Snorkelling gear and life jackets supplied; English-speaking guide keeps things moving
- Viewpoint hike rewards you with unobstructed island vistas at mid-morning
- Breakfast before departure and proper Thai buffet lunch included
- Hotel pick-up from six Samui beaches removes transport headache
- Sea turtle sightings possible, though never guaranteed
- Uncrowded feeling compared to Samui beach day-trips
What to expect
Jake's crew met at their hotel early morning for the transfer to the pier. Once aboard, you'll get breakfast and a briefing before heading out. The boat ride to Koh Nang Yuan takes roughly an hour — it's calm water if you're prone to seasickness, though you'll be on a passenger ferry-style vessel. First stop is snorkelling among the coral and tropical fish. The reef here is intact and busy with life. Around mid-morning, there's a guided hike to the viewpoint — it's short but steep in places, and you'll want decent footwear. Lunch is back on the boat or ashore, Thai-style buffet with fresh options. Afternoon pivots to Koh Tao, where you'll snorkel again at different sites. Jake noted the pace felt unhurried — plenty of water time rather than rushing through tick-boxes. The return to Samui takes another hour-plus, arriving mid-afternoon.
What travellers say

- Snorkel gear and breakfast included — fewer hidden costs up front
- English guide with local reef knowledge keeps you safe and informed
- Hotel pick-up from main Samui beaches cuts out taxi stress
- Unhurried pace — genuine time in the water, not a box-ticking blur
- National Park fees and extra transfers add cost if you're outside main zones

Good to know
Snorkelling gear is decent and included, so you don't need to hire separately. The guide speaks clear English and knows the reefs. Hotel transfers mean no scramble to book a taxi. The two-island format gives variety — different coral formations, different fish populations. Lunch is genuine Thai food, not tourist resort fare.
National Park fees (250 baht adults, 150 baht kids) aren't in the base price — budget for those. If you're staying outside the six listed hotel zones, transfers cost extra (700 baht one way). The hike to the viewpoint has some steep steps and loose footing; not ideal if you have dodgy knees or poor fitness. Early starts aren't everyone's cup of tea. Pregnant travellers, those with heart conditions, spinal injuries, or high blood pressure should skip this. The boat can feel crowded if it's a busy day. Sea turtles are rare these days — don't bank on spotting them. Snorkelling ability and swimming comfort are assumed, so if you're new to it, mention this to the guide. Bring reef-safe sunscreen and a rash guard to reduce UV exposure and protect the coral.
