Koh Samui: Koh Tan and Koh Madsum Half-Day Tour by Catamaran
Book on GetYourGuide →Operated by One Asia Corporation · Bookable on GetYourGuide
Speed, sea, and pigs in one run.
This half-day Koh Samui catamaran tour is a fast way to hit Koh Tan snorkeling and Koh Madsum Pig Island without a full day commitment. I like the mix of active water time plus easy downtime on the islands, and I also like the practical onboard setup (snorkel gear, life jackets, and a crew focused on keeping things safe and smooth). One thing to consider: snorkeling can be hit-or-miss for fish depending on conditions, so don’t plan your day around guaranteed big sightings.
The boat ride itself is part of the fun.
You get a comfortable, speedy catamaran with plenty of space to lounge, plus refreshments and snacks during the trip. In reviews, the inflatable slide, time in the water, and the overall friendliness of the crew come up again and again. A possible drawback is that the schedule can feel tight if you’re hoping for long, quiet beach time, and in at least one case there was little to see at the snorkel spot.

Key things I think you’ll notice right away

- Two island stops in four hours so you get variety without travel fatigue
- Koh Tan coral-reef snorkeling with provided gear and a full water-focused plan
- Pig Island time at Koh Madsum (including feeding and petting in shallow water)
- Inflatable slide on the catamaran that turns the trip into a day-boat party
- Onboard comfort like multiple seating zones and even an air-conditioned room
- Food included (lunch and dinner), plus seasonal fruit, drinks, and water
A four-hour catamaran loop that actually fits real schedules

This is the kind of half-day tour that works when you’re short on time on Koh Samui but still want more than just beach hopping. You’re out on the Gulf of Thailand on a power speed catamaran for a 4-hour block, and the plan is built around water time: snorkeling, paddling, swimming, and an onboard slide.
What makes this tour appealing is that it layers experiences. You start with the coral island snorkeling side (Koh Tan), then switch to the playful, photo-friendly animal encounter at Koh Madsum, often called Pig Island. That change of pace is smart. After coral-water activity, you don’t have to keep doing the same thing—you get a beach break and pig time.
If you’re the kind of traveler who likes to go-go-go, you’ll probably enjoy the packed flow. If you want slow, scenic wandering with no motion, this may feel too busy.

From Koh Samui pickup to Ocean King pier: how the trip starts

Pickup is included, and the operator serves several Koh Samui areas. You can be collected from Mea-Nam, Bophut, Bangrak, Choeng Mon, Nathon, Chaweng, Chaweng Noi, Lamai, and Hua Tanon. The pickup windows depend on your location—typically a morning run from about 7:45 AM to 8:30 AM, or an afternoon pickup in the 12:00 PM to 2:00 PM range.
Here’s how to use that info wisely: show up prepared for a bit of waiting. One traveler noted getting to the boat area nearly an hour early. That’s common with shared transfers and multiple pickup points. If you’re hungry, sun-sensitive, or easily bored, plan for it—bring sunscreen, water in your own bottle if you prefer, and keep your sunscreen accessible.
Once you reach the pier, you board the catamaran and your day really kicks in. The trip is designed to run on a shared timetable, so if you’re going to change plans last minute, don’t. You’ll get the smoothest experience if you keep your morning or afternoon schedule flexible.
The catamaran ride: space, comfort, and how to enjoy the wind

Catamaran days live or die on the boat. In this case, the boat checks a lot of boxes. Expect a setup with seating in multiple areas—front, middle, and top—so you can choose shade or sun depending on your mood. Reviews also mention an air-conditioned room, plus plentiful lounge space like sofas and beanbag-style comfort. Even the bathroom situation impressed some travelers: more than one toilet onboard and generally good facilities.
The slide and “time in the water” parts matter, too. When the day hits the coral/snorkeling area, the crew sets up the inflatable slide for splash time. So you get a natural rhythm: move, snorkel, paddle/swim, then break the tension with a playful moment right off the boat.
Practical tip: if you get motion sick, this is still a catamaran with speed. That can be great (short ride, quick stops) but not always ideal for sensitive stomachs. The tour’s medical guidance says it isn’t suitable for people with heart problems or pre-existing conditions, and it specifically flags people who should avoid the tour due to health risks. If you’re unsure, take it seriously.
Koh Tan (Coral Island): snorkeling and kayaking with real expectations

Koh Tan—often called Coral Island in this context—is your first major stop. This is where the tour focuses on snorkeling with provided equipment and life jackets. The plan also includes kayaking time.
Here’s what to expect underwater, based on the experience people reported: you’ll see colorful fish and coral formations, and the possibility exists of larger wildlife like sea turtles. That’s the dream scenario, and it’s why snorkeling trips are so popular. At the same time, one traveler specifically noted that fish weren’t visible at the snorkel stop on their day.
So how do you set yourself up for success? Go in expecting clear water and coral structures, but don’t anchor your entire satisfaction to seeing a long list of fish. Your best strategy is to focus on the water clarity, the act of snorkeling itself, and the overall chance to spot something interesting.
Kayaking is another layer. Some travelers found kayaking available as an optional activity and noted that it can carry an extra fee (one mentioned 300 baht). If your priority is paddling, ask your provider on the day or confirm ahead of time what’s included in your exact departure. Better to know before you’re already on the boat.
Also, remember you’re on a half-day timeline. The snorkeling stop is about one hour, so you’ll want to be ready when you’re called. Sunscreen matters here—coral water time still equals sun time.
Koh Madsum / Pig Island: feeding pigs, quick beach time, and photo moments

After Koh Tan, the tour heads to Koh Madsum, known as Pig Island because of the friendly pigs that spend time in and around the shallows. You’ll get about an hour of break time on the island, plus food elements later in the flow.
What makes this stop memorable is the interaction. You can wade in shallow water and feed and pet the pigs. This is one of those activities where you’ll likely end up laughing, even if you’re not the “animal person.” It’s also an easy photography setup: pigs congregate near people, and the light often makes for clear, playful shots.
A couple of practical considerations:
- Respect the animals and keep your distance when asked. Don’t treat it like a zoo ride.
- Expect sand and splashes. Plan footwear and clothes accordingly.
- If you’re sensitive to animal contact, you’ll need to decide quickly whether this stop fits your comfort level.
There’s also an alternative: some people just relax on the beach, walk the shoreline, and enjoy the scenery without getting too hands-on. That flexibility helps families and mixed groups.
One review called out the amount of pig time as a standout and mentioned there were a lot of pigs during their visit. If your goal is maximum pig interaction, arrive ready for a hands-on portion and don’t spend your whole hour just searching for the “perfect” moment.
Snacks and meals at sea: lunch, dinner, fruit, and drinks included

Food on boat tours often ranges from “fine” to “survival food.” This one lands more firmly in the good camp. Lunch and dinner are included, along with seasonal fruits, drinking water, and soft drinks on board.
From reviews, the lunch spread looked like a mix of Thai dishes plus familiar comfort foods. Some travelers mentioned options such as fried chicken and rice/noodle dishes. Fruit was described as fresh. One person even flagged that there should be more vegetarian options, while another mentioned their vegetarian spouse enjoyed the food.
So here’s the practical takeaway: if you’re vegetarian, you may do better with a short heads-up to the operator before your day. The tour doesn’t claim a full vegetarian menu, but the fact that a vegetarian traveler reported enjoyment suggests you’re not guaranteed to be stuck with nothing—still, don’t assume.
You’ll also appreciate that drinks and water are included. When you’re in sun and salt air, dehydration sneaks up fast. If you don’t like drinking plain water, remember soft drinks are included too.
Timing and pacing: how the half-day stays packed but not chaotic

This trip is built to move. You’re on the catamaran for the sea travel, you’re snorkeling and kayaking in set windows, and you’re on Koh Madsum for a break before you head back to Koh Samui.
The flow is generally:
- Transfer from your pickup area to the pier
- Koh Tan stop for snorkeling and kayaking
- Koh Madsum stop for pig island time and scenic breaks
- Food moments on board
- Return to Koh Samui
What makes this feel manageable is the mix of activity types. You’re not stuck doing one thing for hours. Even if snorkeling isn’t amazing that day, you still have the inflatable slide, paddle options, and pig island interaction to carry the experience.
That said, you should still consider how you handle motion and switching activities. If you’re the type who gets frustrated by schedule changes, this might not feel relaxing. But if you like organized adventure, it’s well paced for a half-day.
Price and value: is $70 per person worth it?

At $70 per person for a 4-hour catamaran tour, you’re paying for three things at once: transportation from your hotel area to the pier, a boat day with multiple water activities, and onboard meals and drinks.
What pushes the value higher than a basic boat ride:
- Snorkeling equipment and life jackets are included
- Lunch and dinner are included, plus fruit and soft drinks/water
- The boat experience includes entertainment like the inflatable slide
- Round-trip transfer to the pier is included
What could affect value for you personally:
- The national park fee is not included
- Some activities may have extra charges depending on what’s available on the day (kayaking is an example people mentioned)
- Fish sightings for snorkeling can vary
For many people, the included meals and the variety of activities are what make the price feel fair. If you’re planning to pay separately for snorkeling gear, a tour guide, and a boat, this is often the more cost-effective way to pack in two islands plus a sea-activity boat day.
What to bring for Koh Tan and Pig Island (so you’re comfortable fast)
The essentials for this tour are basic, but don’t skip them because you’ll get wet and you’ll be in sun.
Bring:
- Sunglasses
- Swimwear
- Sandals (that won’t instantly slide off when you step into the shallows)
- Camera
- Sunscreen
- Comfortable clothes / beachwear
- Cash
That last one matters because the tour notes that cash may be needed for personal expenses, and some add-ons can have extra fees. Also keep your phone secure during splash moments and bring a towel if you have one you trust.
If you forget sunscreen, you’ll pay for it here. The combination of sun + wind on the catamaran can fool you into thinking you’re not getting burned.
Safety, insurance, and health limits you should respect
This isn’t positioned as an extreme sport tour, but it does include speed on the water and time in and around the sea. The tour provides insurance, and it includes life jackets and snorkeling gear.
Still, the “know before you go” info is clear about limitations. The tour isn’t suitable for:
- Pregnant women
- People with back problems
- People with heart problems
- People over 60 years
- People with pre-existing medical conditions
Insurance also has boundaries. It covers only for 24 hours after the activity starts, and it won’t cover certain ages or very young children (children aged 0–3) and other health-related exclusions are listed.
My advice: if you’re outside the comfort zone for your body’s limits, don’t treat this like a casual sightseeing hop. Choose something calmer and lower risk instead.
Should you book this Koh Samui catamaran tour to Koh Tan and Koh Madsum?
Book it if you want a half-day that feels like a full day’s worth of fun. This is especially good for families, groups, and couples who want real water time: snorkeling at Koh Tan, paddling/swimming options, and the unmistakable pig island experience at Koh Madsum. I also think it’s a strong pick if you care about comfort onboard, because multiple reviews call out the boat space, onboard toilets, and even an air-conditioned room.
Skip or reconsider if:
- You’re hoping for guaranteed, abundant fish sightings while snorkeling
- You’re sensitive to motion on faster boats
- You have medical conditions or fall into the tour’s health limit categories
If you do book, aim to be mentally flexible. The best days are the ones where you enjoy the mix—snorkel for what you can see, splash on the slide, then spend your Koh Madsum hour actually interacting (or relaxing) without overthinking it.
