A quick speedboat day beats planning. This Koh Tan and Ko Mat Sum snorkeling trip from Koh Samui is built for an easy morning: hotel pickup, a fast ride out to two islands, time with snorkel + kayak gear, and a fresh-cooked Thai lunch on Ko Mat Sum. I like that it keeps the pace simple (you show up, they move you), and I also like the practical inclusion of life jackets and snorkeling masks so you are not scrambling for gear. One thing to consider: the experience can include long road transfer and waiting time depending on where you’re picked up, and Ko Mat Sum is also known for pigs—fun for some, messy for others.

You’re usually on the water early, with a speedboat hop from the Samui side toward Koh Tan (about 15 minutes), then you spend the rest of the morning doing water time and island time before lunch. The reef viewing and staff energy are real bright spots in the feedback, and you’ll also want to plan for a short, scheduled snorkeling window rather than all-day reef drifting.

Key Highlights at a Glance

• Hotel transfers from many Koh Samui areas, including Lamai, Chaweng, Bophut, Maenam, Bangpor, and more
• Koh Tan snorkeling + kayaking time with mask and snorkel provided
• Ko Mat Sum (often called Pig Island) with beach lounging, sunbeds, and kayak time
• Thai lunch on Ko Mat Sum with soft drinks and fresh fruit included
• Small island-day pacing (max 30 people) with a ride cap of about 5–6 hours total
• A small admission charge (50 THB per person) that is not built into the base price

Koh Tan and Ko Mat Sum: why this speedboat loop works

This is one of those Koh Samui tours that makes the island-hopping part feel effortless. You’re not negotiating boats, not chasing meeting points in the heat, and not figuring out which pier is the right one. The day is designed around a straightforward rhythm: pickup, speedboat to Koh Tan, then time on Ko Mat Sum.

The best part is that the islands are close together. Koh Tan is where you get your reef-and-fish snorkeling time, and Ko Mat Sum is where you slow down with kayaking, swimming, and beach time. If you are trying to sample both islands without turning your whole day into logistics, this fits.

Price and value: what about $50 really includes

At about $50.15 per person, this trip can feel like a bargain because so much is bundled. You’re getting hotel pickup from a wide list of areas, a speedboat transfer, and the core water activities supported with gear.

Included basics that matter in real life:

• Snorkeling mask and life jacket
• Kayak and sunbed
• Soft drinks (water and cola) plus fresh fruit
• Accident insurance
• A meal while you’re on Ko Mat Sum (Thai lunch is the key piece)

The one extra cost you should plan for is the admission fee: 50 THB per person. It’s a small number, but I’d rather you show up knowing it exists than be surprised mid-day.

If you are comparing to DIY: private boats can get expensive fast on Samui, and group tours usually come out cheaper. This one hits a sweet spot if your priority is getting on the water early without paying private-boat prices.

Morning logistics from Koh Samui: pickups, piers, and time on the road

This tour starts in the morning around 9:00 am. Pickup coverage is broad—Lamai, Butterfly Garden, Chaweng, Bangpor, Maenam, Bophut, Cheongmon, Bangrak, and more. That’s important because transfers are a big part of your comfort level. You want your day to start with less stress, not more.

Still, here’s the reality check: some feedback points to long waiting and a lot of road time before the boat portion. That can happen with shared transfers when the route has multiple hotel stops. If you hate sitting around in traffic, you’ll want to set expectations that the schedule may feel slower than the speedboat portion suggests.

Also note the extra transfer charge: 700 Baht per person, per way, for areas like Nathon, Taling Ngam, Pagka, Lipanoi, and Lipayai. If you’re outside the included pickup list, that can change the value.

Speedboat to Koh Tan: reef time with masks and life jackets

Once the boat portion begins, the pace feels like what you paid for. You ride from the Samui side toward Koh Tan in about 15 minutes. When you reach Koh Tan, you get your snorkeling slot and kayaking time, with snorkeling mask gear provided and a life jacket for safety.

What you should expect underwater: clear, fish-filled water and coral you can actually enjoy during a timed session. In the strongest feedback, people called out lots of fish and amazing coral, and they also said the staff helped them get confident in the water quickly.

This part of the day is also the most weather-sensitive. The operator requires good weather, and if conditions fail, you’ll be offered a different date or a refund.

Thong Krut Beach: what it means in the real flow of the day

You’ll also see Thong Krut Beach show up in the route details. In practice, this usually means it’s part of the transfer-to-pier flow on Samui’s south side rather than a major standalone attraction. Think of it as a piece of the machine that gets you from hotel to boat—not a separate excursion you should mentally plan around.

If you’re the type who likes a clear, predictable itinerary, this can feel vague. But it also means you’re not spending extra energy deciding where to go. You follow the group, and they handle the handoff points.

Ko Mat Sum (Pig Island): beach time, sunbeds, and kayaking

Ko Mat Sum is where the day turns into island-time. You typically travel over after Koh Tan and then spend a chunk of time on Ko Mat Sum for kayaking, swimming, and relaxing. You also get sunbed access here, plus the meal portion.

This is also the island most associated with the Pig Island vibe. One review described it as a circus of sorts, because pigs are a big part of the experience and can get fed by day-trippers. If you like animals and don’t mind a more chaotic scene, it can be entertaining.

If you prefer nature quiet, you should know the other side: pigs mean mess. It’s not “disgusting every moment,” but you should expect smells and poop where people keep feeding them. Plan accordingly by not getting too close, keeping your distance from pig food zones, and treating it as an animal encounter you watch, not something you get up in.

Lunch on Ko Mat Sum: the meal break that people remember

The lunch is part of why this tour earns decent ratings. Feedback repeatedly points to the meal as delicious and a real highlight of the day.

You’re looking at a Thai lunch on Ko Mat Sum, typically served with soft drinks (water and cola) and fresh fruit. That combination matters because you’ll likely work up an appetite from sun and water time.

This is also a practical win: you don’t have to hunt for lunch while the group is at sea or between islands. Your day is set up so you can eat when you land on Ko Mat Sum, then return to beach time.

Snorkeling time: a short window, good planning, don’t overthink it

A key theme in feedback is that snorkeling can be limited to a timed window—people reported around 40 minutes of snorkeling time. That’s not full-day snorkeling, but it’s enough time to enjoy fish and coral if you’re paying attention and moving at the right pace.

Here’s how I’d approach it:

• If you’re a beginner, the short slot is actually a plus. You don’t have to stay in the water until you get tired.
• If you’re an experienced snorkeler hoping for long reef sessions, you may feel a bit rushed.

The good news: the reef quality seems worth the effort based on the strongest comments. The main variable is not the snorkeling itself—it’s how clear the water is and how the day’s schedule lines up with your group.

Group size and comfort: max 30, shared transfers

This tour caps at 30 travelers. That’s big enough that it will feel like a group day, not a private escape. But it also keeps it far from mass-tour chaos in most cases.

The other comfort factor is the shared transfers. If you want minimal waiting, go in with a “flexible schedule” mindset. If you’re traveling from an included pickup area and not too far from the route, your day usually feels smoother. If you’re near the edge of coverage, it can add extra time.

Safety and who should skip it

The tour includes accident insurance, plus life jackets and snorkeling gear. That’s the practical side.

Health-wise, it’s explicitly not recommended if you’re pregnant or if you have high blood pressure, heart disease, or bone diseases. That isn’t a small detail—you should treat it as a real safety flag.

Also, this activity isn’t recommended for guests arriving by cruise ship or large boat, likely because of transfer logistics and timing constraints.

Who this trip is best for (and who it isn’t)

This is a solid choice if:

• You want Koh Tan snorkeling + Ko Mat Sum beach time in one morning
• You’d rather rely on hotel transfers than arrange a private boat
• You enjoy short, scheduled water sessions and a clear plan

It’s less ideal if:

• You hate shared transfers and could be upset by long road waits
• You’re turned off by the Pig Island animal-feeding atmosphere and mess factor
• You’re expecting hours of nonstop snorkeling

For families, there’s a child ticket age range of 4–11 years. Just keep in mind the same schedule and water timing applies to everyone.

Tips to make the day smoother (no surprises)

1. Arrive with water shoes if you have them. You’ll be in and out of water zones and on beachy areas.
2. Bring sunscreen and a dry bag. The trip includes multiple water moments, and sun is the one thing you can control.
3. If Pig Island affects your mood, set your mindset: watch from a comfortable distance and keep your expectations realistic.
4. Consider where your pickup is. If you’re far from the included pickup list, check whether the extra 700 Baht per person per way applies.
5. Plan for a timed snorkeling session, not a long floating reef cruise. If you want more time underwater, you’ll likely need a separate snorkeling plan later.

Should you book this Koh Madsum and Koh Tan speedboat trip?

I’d book it if you want a simple, morning-focused Koh Samui day: Koh Tan for snorkeling and reef viewing, then Ko Mat Sum for kayaking, beach lounging, and lunch—without private-boat costs.

I would hesitate if:

• You’re very sensitive to delays from shared transfers
• You dislike Pig Island’s animal-feeding chaos and mess
• You’re expecting long snorkeling durations without schedule pressure

If you match the trip style—structured morning, short snorkeling slot, island time after—that $50-ish price can feel like good value for a two-island day. If your ideal day is quiet and unhurried, you may want a more flexible alternative.
