Okay, Pig Island. Let me start with the obvious confusion — yes, this is a thing in Thailand, and no, it’s not the Bahamas one you’re probably thinking of.
The Bahamas pigs (Exuma Cays) are the famous ones. They’ve been on Instagram for a decade. What people don’t always realize is Thailand has its own version — smaller scale, less Instagram-famous, but genuinely worth a morning if you’re already based on Koh Samui and you’re into the concept.
The real name is Koh Madsum. Or sometimes Koh Matsum, depending on who’s romanizing it. Locals usually just say “Pig Island” when they’re talking to tourists because that’s what everyone else calls it. It’s a small-ish island about 30 minutes south of Samui by speedboat, usually paired with a stop at Koh Taen for snorkeling, which together makes for a pretty tidy half-day trip.
Here’s the honest breakdown of what the experience is actually like, what’s worth knowing before you book, and whether it’s a good fit for your trip.
Wait, There Are Really Pigs Just… Walking Around a Beach?
Yes. There are real pigs. They walk around on a real beach. They swim in the shallows. Some of them will come right up to the boat as it approaches.
The backstory, as I’ve heard it from people who’ve been going longer than me: the pigs were brought to the island by locals decades ago, nothing unusual for rural southern Thailand. At some point, tour operators clocked that tourists found the swimming pigs charming — and a thing was born. The pigs have been fed and looked after by the tour industry ever since.
So these aren’t wild boars in a native habitat. They’re domesticated pigs who live on a beach and have built up a pretty cushy routine around getting snacks from tourists all day. Kind of like the stray dogs you see hanging around temples, except beachfront and significantly pinker.
There are usually a decent mix — big adult pigs, younger ones, sometimes piglets depending on the season. Numbers change over time. On a normal day you might see somewhere between 10 and 25 pigs on the beach or in the shallows.
Getting There
Most people do Pig Island as a half-day or full-day tour from Koh Samui. A few options:
- Speedboat tour from Koh Samui — the standard choice. 20 to 30 minutes each way. Usually combined with Koh Taen snorkeling. Half-day length.
- Longtail boat — slower, cheaper, more traditional. Closer to 45 minutes each way. Less of a proper “tour” feel, more of a rented-boat feel, which honestly can be more fun.
- Private charter — worth it if you’re a family or small group and you don’t want to share the experience with 30 strangers. More expensive but worth every baht if you can swing it.
- From Koh Phangan — possible but less common. Longer transit, fewer operators running the route. If you’re based on Phangan it’s doable, but I’d usually suggest pairing it with an island-hop over to Samui rather than day-tripping direct.
Ao Thong Krut pier on the south coast of Samui is the usual departure point. If you’re staying in Chaweng or Lamai, budget extra time for the transfer to the pier — it’s a 20 to 30 minute ride, and the roads across the south of the island can be slow when the school traffic hits.
What Actually Happens When You Arrive
Okay, the actual experience. Here’s what to expect:
Your boat slows down as it approaches the beach, and if the timing is right, you’ll start seeing pigs wading into the water to meet you. That’s the famous image — pig in the turquoise shallows, sand beneath, hopeful little face looking up at your boat. That image is real.
Then you get off the boat. The pigs are very used to people. They know the boat means snacks. This is where it gets slightly chaotic.
Some pigs are calm. Some pigs are pushy. The bigger adults especially will nose right into your legs if they think you’re holding food. They don’t bite in an aggressive way, but they can nip if they smell something and you’re slow to hand it over. Not mean. Just firm. In a “I have seen this routine a thousand times and I know how it ends” kind of way.
Most tours hand out designated pig food — usually pellets or cut-up vegetables. Don’t feed them anything random. No snacks from your bag, no bread rolls from breakfast. Their diet is already borderline weird from constant tourist attention, so sticking to the supplied food is the kinder move.
The beach itself is pretty. Soft sand, clear water, limestone hills behind. You get an hour or so to wander around, take pictures, swim a bit. The pigs are the draw, but the setting’s also nice in its own right.
The Koh Taen Part
Most Pig Island tours bundle in a snorkeling stop at Koh Taen, which is a small island right next door. This is actually a lovely add-on and in some cases the snorkeling ends up being the better part of the day.
Koh Taen has shallow reefs accessible right from the beach — you swim out maybe 20 meters and you’re above live coral. Parrotfish, butterflyfish, the usual reef suspects. It’s not world-class in the same league as Similan Islands or the stuff around Koh Tao, but for a half-day tour from Samui, it’s a solid snorkel with genuinely healthy coral.
Most tours give you 45 minutes to an hour at Koh Taen. That’s usually enough to get a proper look. Bring your own mask if you’ve got one — the rental gear on tour boats is hit or miss, and nothing kills a snorkel like a mask that won’t seal.
Is This Ethical? Let’s Talk About It.
I feel like I have to address this honestly because anyone who cares about animal welfare is going to think about it, and the internet has strong opinions in both directions.
The pigs on Koh Madsum are not being mistreated in any obvious way. They’re well-fed (arguably overfed), they have shade, they have water, and people who’ve been visiting for years say the same pigs keep showing up — they’re not being rotated out or replaced suspiciously often. There’s a caretaker presence on the island who keeps an eye on them.
That said, this is also not “wildlife” in the way that, say, seeing dolphins in Ang Thong is. These are domestic animals living in a tourist-feeding economy. The ethics of that feel different to everyone. Some people find it charming. Some find it uncomfortable. Both positions are reasonable.
My honest take: if you’re fine with petting zoos, you’ll be fine with Pig Island. If you’re not, you probably won’t love it regardless of setting. Either answer is a valid answer.
What I would avoid: tours that let people feed the pigs anything they want, or that encourage picking up or grabbing the piglets. That’s where it crosses a line. The reputable operators keep things reasonably managed — food is controlled, direct handling is discouraged.
Who Will Actually Enjoy This
Let me be direct about fit.
Pig Island is great for:
- Families with kids, especially kids under about 12. This is pretty much unit fun for them. There are pigs. On a beach. Swimming. It is perfect.
- Groups who want a light, novelty half-day that isn’t logistically heavy
- People who want a decent snorkel at Koh Taen without committing to a full-day Ang Thong tour
- Anyone who just wants the photo, which is an honest and valid reason to go
Pig Island is probably not for you if:
- You’re a serious snorkeler or diver looking for the best Thailand has to offer — Ang Thong, Koh Tao, Similan, or Koh Phi Phi’s outer reefs will all give you more
- You specifically want wildlife in the wild — these are domesticated pigs, not a nature encounter
- You don’t like crowds — Pig Island can get busy in the middle of the day with multiple boats arriving at once
- You’re on a tight budget and this would come at the expense of a more substantive island experience
I’d slot Pig Island in as the “one cute half-day” in a larger Samui-area trip, not as a main event. On that scale, it works really well.
Practical Notes
The stuff worth knowing beforehand:
- Morning is better than afternoon. Go on the first boat of the day if you can. The pigs are more active, the beach isn’t overrun yet, and the light is better for photos. By lunchtime you’ll be sharing the beach with three or four other boats.
- There’s a small island entrance fee — usually around 100 baht per person, paid on the beach or sometimes rolled into your tour price.
- Bring your own water. Most tours provide drinks but the supply can be light. Don’t count on it for a four-hour trip.
- Reef-safe sunscreen matters more here than people think. You’ll be in the water at Koh Taen, directly above live coral. Regular sunscreen is not great for reefs.
- Don’t overdress. You will be in and out of the water. Wear your swimwear from the pier. Save the dry clothes for the ride back.
- The pigs will photograph you back. Their tusks are not razor-sharp but they’re not nothing. If you crouch down for a selfie with a banana in your pocket, expect the pig to locate said banana with surgical precision.
So — Is It Worth It?
For most people visiting Koh Samui, yeah. Kind of. It’s not the best thing you’ll do in Thailand. It’s not even the best thing you’ll do in Samui. But as a half-day detour in the middle of a broader trip, it’s genuinely fun and doesn’t require much planning.
If you’ve got kids, I’d say it goes close to must-do. The novelty factor is real and they’ll talk about it for months after.
If you’re a solo traveler or a couple who’s already packed a week of island stuff into the itinerary, Pig Island might feel like a light-novelty slot you can skip without missing much — particularly if you’ve already got strong snorkeling booked elsewhere.
My personal take: the combination of pigs-on-beach-at-sunrise plus a proper snorkel at Koh Taen plus being back at your Samui hotel before lunch makes for a really pleasant morning. Low stakes, low stress, a decent bit of fun, and a handful of photos you’ll actually keep.
