Two islands, one simple speedboat morning. You get a structured day out to Koh Tan and Ko Mat Sum, with snorkeling, kayaking, beach time, and a Thai lunch—without having to bargain for a private boat. The big win here is the included hotel transfer from several popular Samui areas, which saves you from the usual pier-planning headache.

I also really like that the snorkeling setup is practical: life jacket on, and mask/snorkel provided, so you can focus on seeing fish and coral instead of hunting for gear. The only real drawback to keep in mind is that the day can involve extra road time—so if you hate waiting in vans before the boat, this might test your patience before you even hit the water.

Key Things To Know Before You Go

• Hotel pickup from many Samui areas: Lamai, Butterfly Garden, Chaweng, Bangpor, Maenam, Bophut, Cheongmon, Bangrak, and more.
• Speedboat transfer to the snorkeling area: about 15 minutes from Tong Grood to Koh Tan.
• Snorkeling gear included: mask and snorkel plus a life jacket.
• Kayak and sunbed time on Ko Mat Sum: included for relaxing and getting out on the water.
• Thai lunch plus soft drinks and fruit: served during the Ko Mat Sum portion of the day.
• Small admission fee: 50 THB per person, payable separately.

Koh Tan and Ko Mat Sum: Quiet Water Time You Can Do Without Booking a Boat

This trip is built for people who want an island-and-snorkel morning on Koh Samui, but don’t want to spend their holiday price-shopping boats. Koh Tan and Ko Mat Sum sit off Samui’s southern edge, and that matters because the day feels like a true getaway instead of just a beach stop.

What you’re paying for is structure. You show up at pickup, get transported to the pier, and then the crew runs the sequence: speedboat hop, snorkeling, kayaking/beach time, and food. It’s the kind of plan that works especially well if you’re traveling with friends, family, or anyone who doesn’t want to handle timing, tickets, and logistics.

Getting There From Samui: Transfer Time Is Part of the Deal

The day starts with hotel pickup, typically around 8:30–9:00 am, with a morning departure (start time listed as 9:00 am). From there you head toward the pier, then take a speedboat transfer—about 15 minutes—to Koh Tan.

Here’s the one thing to mentally budget for: Samui pickup routes. Some people end up spending longer in vehicles before reaching the departure point, and the experience can feel like more driving than boating before the fun starts. If you’re the type who gets antsy waiting around, bring patience (and a small snack if you can).

Snorkeling Setup That Doesn’t Waste Time

You don’t need to bring your own snorkel kit. The tour provides life jackets and a snorkeling mask and snorkel, which makes it much easier to jump in and start watching fish.

Snorkeling is part of both the Koh Tan and (later) Ko Mat Sum portions of the day. Koh Tan is your first reef session, and Ko Mat Sum includes more beach time plus chances to swim and snorkel again depending on what the schedule allows that day.

Timing matters, and the snorkeling stop is set up to be manageable. In practice, you’ll get a focused window in the water rather than a vague, all-day free-for-all. One review noted that about 40 minutes is plenty to see plenty of coral and fish, which matches the overall idea of this being a structured morning activity—not a drifting, uncertain snorkel day.

Koh Tan: Reef Views Plus Kayaking-Style Water Time

Koh Tan is where the day gets started on the water. The speedboat hop is quick, which helps you feel like you’re earning your beach time right away.

On Koh Tan, you’ll have a chance to snorkel and also use a kayak. This combo is smart. Snorkeling lets you look at the reef and fish up close, while kayaking helps you get that “island day” feeling even if you don’t stay in the water the whole time.

If you’re hoping for a calm, easy start, Koh Tan tends to deliver that. The focus is reef viewing and getting your bearings, not rushing between a bunch of unrelated stops.

Ko Mat Sum: Beach Time, Kayaks, and Lunch That Makes It Worth the Boat Ride

Ko Mat Sum (also written as Koh Madsum) is where the day shifts into relaxing mode. You’ll spend about 3 hours here, with swimming, snorkeling opportunities, and a real chunk of beach time.

This is also where the tour handles the food. You get a Thai lunch on Ko Mat Sum, along with soft drinks (water and cola) plus fresh fruit. One of the strongest themes around the meals is that they’re actually tasty and filling, not just a token sandwich situation before the next activity.

You’ll also have sunbeds and the kayak available here. That matters because it gives you options:

• Stay on the sand and cool off between water sessions
• Paddle around without needing to be a pro
• Swim and snorkel when the water feels right

Thong Krut Beach Stop: A Short Pause Built Into the Day

The trip includes a 1-hour stop at Thong Krut Beach. Depending on how your route lines up, this can feel like a breather—time to stretch, reset, and shake off the earlier travel.

It’s not the main event, but it helps break up the day’s movement. If you’re doing this as a single big activity on your Samui itinerary, that extra hour can make the whole experience feel less rushed.

Cost and Value: Why This Tour Works at Around $50

At about $50.15 per person, you’re paying for far more than a boat ride. What’s included is the real value: hotel transfer (from multiple areas), snorkeling gear support (mask/snorkel and life jacket), kayak, sunbed, and lunch with soft drinks and fruit.

Then there’s the small catch: an admission fee of 50 THB per person that you pay separately. It’s not huge, but it is one more thing to plan for. Also note the extra transfer charge of 700 Baht per person per way if you’re picked up from areas outside the listed transfer zone (Nathon, Taling Ngam, Pagka, Lipanoi, Lipayai).

The overall value makes sense if you’re not trying to build your own boat day. If you compare this to arranging a private boat plus gear plus lunch, this starts to look like a budget-friendly way to hit the highlights without turning your morning into a logistics project.

Group Size and Timing: Small Enough to Feel Organized

This isn’t a massive cattle-call tour. The group size has a maximum of 30 travelers and it also has a minimum of 10 people to run.

That usually means you’ll get a day that feels organized rather than chaotic. You still share the experience with a group, of course, but it’s set up for normal human pacing: pickup, boat transfer, snorkeling sessions, then beach time with food.

There’s also accident insurance included, which is comforting for something involving water time.

A Note on the Pig Island-Style Stop You Might Encounter

One thing I’d watch for is that some versions of this outing include a time at a pig island style stop (named that way by guests). In one description, it was a longer island period with kayaking and lunch, followed by snorkeling.

That can be fun if you enjoy oddball travel moments and wildlife-photo opportunities. But if you’d rather keep the day focused strictly on reef snorkeling and beach relaxation, the pig portion can feel like a detour.

If you know you’re not into animal-centric photo stops, ask the operator what the day’s exact stops are before you go, or choose a different island itinerary.

Practical Tips for a Smoother Day on the Water

This is a morning trip, and it’s water-based, so your comfort depends on a few small choices.

• Pack a light layer for boat breeze and a change of clothes for after.
• Bring cash for the 50 THB admission fee.
• Use reef-friendly habits if you have them (simple things like not touching coral help everywhere).
• If you’re picky about timing, plan your expectations around group pacing, not private-boat freedom.

Also keep in mind the weather rule: it requires good weather. If it’s canceled due to poor conditions, you’re offered another date or a full refund.

Who This Trip Fits Best

You’ll likely enjoy this most if you:

• Want a structured Samui island day with snorkeling and kayaking
• Prefer included transfers over DIY pier planning
• Like the idea of having lunch and amenities handled for you
• Are comfortable in a shared group setting (up to 30)

It’s also a reasonable option for kids with a ticket age between 4–11 years, assuming everyone in the group is comfortable with the water time.

On the other hand, this is not recommended for pregnant guests or people with high blood pressure, heart disease, or bone diseases. It’s also not meant for cruise-ship arrivals by large boat.

Should You Book Koh Madsum and Koh Tan From Samui?

I’d book it if you want the easiest path to Koh Tan and Ko Mat Sum with hotel pickup, snorkeling gear support, kayaking, and a real lunch, all for a price that’s usually hard to beat when you factor in logistics.

I wouldn’t book it if long transfer delays before the boat would irritate you, or if you’d be unhappy with the possibility of a pig island-style stop. This trip is a mix of water time and island time, but the day runs on a group schedule, so you don’t get total control.
