About this tour
When Lily from our BugBitten team booked this speedboat snorkel run from Koh Samui, we were after something close by that wouldn't feel rammed with other tourists. Koh Tan and Koh Madsum, just a short blast offshore, delivered on both counts. The day mixes proper reef time with a sprawl on genuinely white sand, wraps in Thai lunch, and runs about 6–7 hours door-to-door with hotel pickups included. It's the kind of half-day that doesn't require you to wake before dawn or sacrifice your whole schedule.
Highlights
- Speedboat ride itself is quick and smooth—no slog to distant reefs
- Koh Tan reef has decent coral and tropical fish, genuinely worth the snorkel
- White sand beach on Koh Madsum feels uncrowded compared to main Samui spots
- Fresh Thai lunch included, not some sad bento box scenario
- Hotel transfers from most Samui areas remove logistical faff
- Relaxed pace—snorkel, laze, eat, done. No rushing between ten stops
- Small-group feel; this won't be 80 people crammed on one boat
What to expect
You'll get picked up from your Samui hotel (morning departure, exact time depends on your location), then head to the speedboat. The ride out takes maybe 20–30 minutes, so no epic commute. First stop is snorkelling at one of the islands; the water's warm, visibility is decent, and you'll see proper reef life without fighting for space. Lily found the fish variety solid—parrotfish, snappers, small groupers—though it's not a pristine wall dive, just a genuinely pleasant tropical reef.
After a couple of hours in the water, you'll beach on white sand for a breather and lunch. This is where the tour lets you properly decompress; the beach is quiet, the pace is yours. Lunch is a proper Thai set—rice, curry, protein, veg—not some hastily assembled sandwich. You'll get soft drinks and fresh fruit too. The whole vibe is low-key; there's no pressure to do another snorkel session if you're knackered. By afternoon, you're heading back to Samui. Total time away is 6–7 hours, so it fits around other plans.

Good to know
This is genuinely non-touristy compared to Phi Phi or Ang Thong snorkel runs. Koh Tan and Koh Madsum stay quiet because they're close and overlooked. If you want reef time without feeling like you're in a theme park, this works. The speedboat is efficient—no dragging; you're there and back in a sensible window. Hotel transfer is a real perk if you're based in Chaweng, Lamai, or Bophut. Lunch is included and actually palatable. It suits anyone fairly fit; no advanced fitness required.
There's a 50-baht island admission fee not flagged in the price. If your hotel is in Nathon, Taling Ngam, or the west side, you'll pay an extra 700 baht each way for transfer—worth knowing upfront. A 10-person minimum means there's a (rare) cancellation risk; the operator will offer reschedule or refund if it doesn't fill. Not suitable if you're pregnant, have spinal issues, poor heart health, or high blood pressure—the speedboat does bounce. Early start typical of Samui tours. Bring reef-safe sunscreen; the midday sun out there is brutal. Water shoes help on the beach.
