About this tour
When Mia from our team took this speedboat snorkel run, we headed out to Koh Madsum and Koh Tan — two quiet islands off Koh Samui's east coast with rocky reefs teeming with coral and colourful reef fish. The five to six hour trip bundles hotel pickup, kayaking, two snorkel stops, a Thai lunch, and plenty of beach time on white sand. It's the kind of outing that feels properly remote despite being close to Samui, and the boat moves fast enough that you're not spending half the day getting there.
Highlights
- Rocky reefs packed with coral gardens and tropically bright fish life
- Kayak paddling around Koh Madsum's quieter coves and rocky outcrops
- Small-village island feel — genuinely unspoiled, maybe 30 locals living there
- White sand beaches for lounging between snorkel sessions
- Fresh Thai lunch included; soft drinks and fruit throughout the day
- Direct hotel transfers from most central Samui spots
- Compact group size keeps it intimate rather than cattle-boat chaos
- Barracuda sightings possible on good reef days
What to expect
You'll be picked up from your hotel mid-morning and driven to the speedboat dock. The boat ride itself is quick and bouncy — expect about 20 minutes across open water with decent swell sometimes. Once at Koh Madsum, you hit the water in a snorkel group; the reef here sits close enough that you're spotting fish within minutes. The rocky coastline is more interesting than a sandy slope, so the marine life clusters tightly. After an hour or so in the water, there's time to either kayak around the island's quieter edges or just sprawl on the beach. The second island, Koh Tan, follows a similar rhythm. Lunch arrives mid-afternoon — properly cooked Thai, not just a sad sandwich — eaten in a sheltered spot on the sand. The return trip to Samui happens in late afternoon, landing you back at your hotel by early evening.

Good to know
The reef here genuinely delivers. Fish density and coral health beat a lot of the heavily trafficked Samui day-trips. The islands feel genuinely quiet — it's not a conveyor belt of tourist boats. Kayaking is a nice bonus if you want to paddle rather than just snorkel. Thai lunch is a cut above the usual tour fare. Hotel transfers save you sorting a taxi.
Minimum 10-person group means occasional cancellations in low season; you'll get advance notice and can rebook. The islands aren't wheelchair-accessible and involve clambering on and off boats, so mobility needs matter. Early starts suit most people better than late risers. Rough sea days happen — this is a speedboat, not a luxury catamaran. Kids aged 4–11 get a discounted ticket, but younger kids might find the boat ride tiring. A 50-baht park fee hits you on arrival (not listed upfront). Extra hotel transfers from the western side of Samui cost extra. The activity rules out pregnant travellers and anyone with heart or bone conditions — take that seriously. Not suitable if you're cruising in; speedboats and large ship schedules don't mix.
