About this tour
When Tom from our team ran this trip from Koh Samui, we found it a solid half-day escape to two quiet islands most tourists skip. A speedboat gets you to Koh Tan and Koh Madsum—close enough that you're not burning half the day in transit—where you snorkel a decent tropical reef, paddle a kayak around the shoreline, and laze on a genuinely peaceful white-sand beach. Thai lunch and soft drinks are thrown in. The islands stay refreshingly low-key because they're not on the standard Samui circuit. Six to seven hours total, including hotel pickup and drop-off.
Highlights
- Snorkel a tropical reef without fighting crowds
- Paddle kayaks through quiet coves around Koh Madsum
- White-sand beach genuinely feels empty, not manufactured
- Thai lunch included beats resort overpriced options
- Close islands mean minimal boat time, maximum beach time
- Small-group vibe—not a cattle-barge operation
- Hotel transfers from most Samui beaches included
What to expect
You'll get picked up from your Samui hotel in the morning and head to the pier for a speedboat ride—it's quick, so don't expect a leisurely cruise. Once at Koh Tan, the snorkelling window is decent; the reef has fish and colour, though don't show up expecting pristine corals. The water's warm and clear enough that even patchy visibility days work. After snorkelling, you'll kayak around Koh Madsum at a relaxed pace—guides stick to shallow, protected areas, so it's not technical.
Then comes the beach time, which is genuinely the highlight. The sand is soft, the shore slopes gently, and you won't see tour groups stacked shoulder-to-shoulder like you do on Phi Phi. Thai lunch arrives around midday—a set menu of curry, rice, fresh fruit—and it's filling. The day's rhythm feels unhurried, though you're never far from the group. Heading back, you'll dock mid-afternoon, allowing time to shower before dinner plans.

Good to know
These islands sit close enough to Samui that you're actually relaxing by mid-morning, not spending your day in a boat. The lack of cruise-ship crowds makes it feel like a proper escape rather than a box-tick. Snorkelling is straightforward—masks and jackets provided—and the reef has enough life to keep you interested. Thai lunch tastes fresh and isn't a token gesture. If you're based on the main beach areas (Chaweng, Lamai, Bophut), transfers are included; that convenience is real.
Minimum group size is 10 people, so last-minute bookings might get cancelled and rescheduled. If you're staying in Nathon or the west coast, you'll fork out an extra 700 baht each way—that stings. The reef is nice but not pristine; don't expect manta rays or hard corals. Not suitable if you're pregnant, have heart or spinal issues, or poor fitness. There's a 50-baht island fee (not listed upfront) that catches some travellers. Early start is non-negotiable. Bring sunscreen—the beach offers no shade.
