You’ve probably seen the photos. A clear turquoise bay, a strip of white sand, and — weirdly — a bunch of pigs wandering around like they own the place. Because they do. That’s Pig Island, just a short speedboat ride from Koh Samui, and it’s one of those places that looks almost too good to be real.
But is it actually worth going? Or is it the kind of thing that looks better on Instagram than it feels in person?
Having spent time out there (and talked to plenty of people who’ve done the various tour options), here’s the honest answer: it depends a lot on how you do it. Get that part right and it’s genuinely one of the most fun, low-key days you can have from Koh Samui. Get it wrong and you’ll spend two hours on a crowded longtail feeling like you’re on a school trip.
Let’s break it all down.
What Actually Is Pig Island?
First, the name. “Pig Island” isn’t actually the island’s official name — locals call it Koh Madsum, which translates roughly to “Breadfruit Island.” But at some point someone brought pigs here, the pigs figured out the beach situation was excellent, and the name kind of stuck for tourists.
The island sits about 10km south of Koh Samui in the Gulf of Thailand, so the water crossing is short — usually 20–30 minutes by speedboat, or 45–60 minutes by longtail, depending on which tour you book. It’s tiny. You can walk the main beach in about 10 minutes. There are a handful of beach chairs, a couple of small food stalls, some very relaxed chickens, and yes, a small group of pigs who hang out near the water and occasionally swim.
There’s also decent snorkeling just off the beach. Not Koh Tao-level snorkeling, but coral, fish, and clear enough water that it’s worth getting in if you’re already there.
The Pigs: What to Actually Expect
Let’s be real about the pigs before anything else, because this is either the main draw or the thing that makes you roll your eyes.
They’re real. There are maybe 6–10 of them depending on when you visit. They roam freely on the beach, they do sometimes swim (especially when encouraged with food), and they’re genuinely entertaining to watch. You can get close to them, feed them if you bring fruit, and take photos. They’re not aggressive — they’re more interested in scraps than in you.
That said, they’re pigs. They smell like pigs. The beach near where they hang out smells like, well, a farm. If you’re squeamish about that or planning to spend your whole day lying on the sand right where they wander, factor that in.
The sweet spot is: spend 20–30 minutes with the pigs when you arrive, get your photos, see if they swim, then move down the beach to the cleaner stretch and snorkel or just float around in the water. That’s basically what everyone does, and it works well.
How to Get There from Koh Samui
You’ve got a few options, and they’re genuinely different experiences.
Speedboat Tours (The Main Route)
Most people going to Pig Island from Koh Samui book a speedboat tour, and most of those tours combine Pig Island with another stop — usually Koh Taen, a larger, quieter island nearby with excellent snorkeling and no pigs (which is actually a selling point after the main event).
The Pig Island & Koh Taen Snorkeling Speedboat Tour from Koh Samui is one of the most popular options because you get the full picture: you visit Koh Madsum for the pig experience, then move to Koh Taen for snorkeling in cleaner water. Hotel pickup is usually included, and the whole day wraps up by mid-afternoon.
If you want to go a bit faster and cover more ground, the Pig Island Speedboat Adventure with Swimming Pigs & Snorkeling adds an extra snorkeling stop and moves quickly between spots. It’s good if you want variety and don’t plan to linger too long at each place.
Longtail Boat Options
Longtail is slower, cheaper, and the experience is completely different. You’re sitting on a wooden boat, engine loud as hell, taking in the coastal views as you chug south. It’s actually kind of nice if you’re not in a rush. You feel more like you’re just… going somewhere, rather than being shuttled on a tour.
The Private Pig Island Longtail Boat Tour is good for couples or small groups who want flexibility — you set the pace, spend as long as you want at each spot, and it feels more like an actual local day trip than a group tour.
Island Hopping Combos
There are also options that combine Pig Island with Coral Island (Koh Tean, different from Koh Taen — yes, the naming is confusing), like the Koh Samui Island Hopping: Coral Island & Pig Island day trip. If you’ve got a bit more time and want to see multiple spots in the area, this is a solid choice.
The Ultimate Pig Island Tour from Koh Samui bundles a lot into one day — pig feeding, kayaking, snorkeling, and a boat lunch — making it one of the most complete options if you want to make a proper day of it.
What the Day Actually Looks Like
Here’s a rough idea of what to expect if you book a standard speedboat tour:
7:30–8:30am — Hotel pickup somewhere on Koh Samui’s south or west coast. This depends heavily on where you’re staying. If you’re in Chaweng, budget extra time.
9:00–9:30am — Arrive at Koh Madsum (Pig Island). The beach is calm at this hour and the pigs are active. This is the best time to be there — before the crowds, before the heat. Spend 30–45 minutes here. Feed the pigs, swim with them if they’re in the mood, take your photos.
10:15am — Move to the snorkeling spot, either just offshore from Koh Madsum or on the way to Koh Taen. Visibility is usually good in the morning. You’ll see parrotfish, clownfish, and decent coral. Depth is shallow enough that you don’t need to be a strong swimmer.
11:30am–12:30pm — Koh Taen stop (on tours that include it). Quieter, less touristed, nicer beach for just hanging out. Some tours do lunch here.
1:30–2:00pm — Back to Koh Samui.
Total time out: around 5–6 hours. It’s a half-day that feels like a full day.
What to Bring
Keep it simple. The beach at Koh Madsum has limited shade, so:
– Sunscreen — bring your own, it’s expensive on tour boats
– Fruit for the pigs — bananas or watermelon work best; some tours provide this, others don’t
– Reef-safe sunscreen if you’re snorkeling — it matters here, the reefs are in decent shape
– A dry bag — keep your phone safe, especially on speedboats where spray is constant
– Cash for drinks/snacks — there are a couple of food stalls on the island; not expensive, but card payment is limited
– Seasickness tablets if you’re prone — the Gulf of Thailand is usually calm, but speedboats bounce more than you’d expect
What you don’t need: anything fancy. This isn’t a dress-code destination.
Is the Snorkeling Any Good?
Honestly? It’s decent. Not life-changing, but genuinely enjoyable.
The best snorkeling in the area is actually around Koh Taen rather than Koh Madsum itself. Koh Taen has a protected bay on its east side with reasonable coral coverage and good fish diversity. You’ll see the usual Gulf of Thailand species — angelfish, surgeonfish, sea urchins, the occasional sea turtle if you’re lucky.
Koh Madsum’s snorkeling is fine — clear water, some coral, a few fish — but it’s shallow and the coral’s taken some bleaching damage over the years. It’s still worth jumping in; just don’t set your expectations at Koh Tao levels.
If snorkeling is really the main reason you’re going (rather than the pigs), you might also want to look at the Full Day Snorkeling Adventure Around Koh Tao for comparison — that’s a longer day trip but the underwater experience is noticeably better.
When to Go
The Gulf of Thailand has its own seasonal rhythm, different from the Andaman coast (Phuket, Krabi). Here’s what to know:
November to April — Best conditions. Clear water, calm seas, the pigs are happy, the beach is perfect. Peak season runs December through February, so expect more people during those months.
May to October — This is the Gulf’s wetter season, but “rainy season” in the Gulf doesn’t mean all-day rain the way it does elsewhere. You’ll often get morning sunshine and afternoon showers. The sea can be choppier and some speedboat tours will be cancelled on bad days. If you’re visiting in this window, book flexible cancellation policies and check conditions the morning of.
The pigs don’t really have an off-season. They’re there year-round.
Kids and Families: Is It Suitable?
Generally yes, with a few caveats. Kids love the pigs — full stop. It’s one of those rare experiences that genuinely lands with a 7-year-old and a 40-year-old at the same time.
The snorkeling is shallow and manageable for kids who can swim. The longtail boat option is calmer if you’ve got little ones who might find the speedboat bumpy or loud.
The main thing to watch is the sun — there’s limited shade on the beach, and the Gulf at midday is intense. Pack sun protection and don’t underestimate it.
How Does Pig Island Compare to Other Koh Samui Day Trips?
This is a fair question, because from Koh Samui you’ve got a lot of options. Pig Island is genuinely fun but it’s not the only game in town.
Ang Thong Marine Park is the big one — a full archipelago of 42 islands with dramatic limestone formations, a saltwater lagoon, and some of the best scenery in Thailand. If you can only do one day trip from Samui, many people would say Ang Thong wins. We’ve got a full breakdown in Exploring Ang Thong Without Booking a Full Tour and How Travel to Ang Thong Differs From Other Thai Islands. The Ang Thong Marine Park Catamaran Tour from Koh Samui is worth considering if you’re choosing between the two.
Koh Phangan is just 30 minutes north — a totally different kind of day if you want to explore an island on foot rather than doing a boat trip.
Pig Island, by comparison, is lower-intensity, shorter, and honestly more fun if you’re not trying to do Something Significant. It’s a great choice if you want a relaxed half-day with a memorable experience and aren’t looking for epic scenery or serious snorkeling. It’s also the cheaper option, which matters.
Do Ang Thong for the scenery. Do Pig Island for the experience.
Tips That Actually Help
A few things that make the day noticeably better:
Book morning departures. By midday the beach gets busier and the sun gets brutal. An 8am boat beats a noon boat every time.
Go mid-week if you can. Weekends (especially Thai public holidays) bring out the group tours in force. Tuesday or Wednesday is a different experience.
Don’t skip Koh Taen. Some tours let you skip the second stop if you want to stay longer at Koh Madsum. Don’t do this. Koh Taen is quieter and the snorkeling is better — it’s the underrated half of the trip.
Lower your phone when the pigs are feeding. You’ll get better photos and you’ll also avoid a pig making a lunge for your arm because it smells like snacks. They’re friendly, but they’re not subtle.
Leave the big camera home. Or bring a dry bag. Speedboats are splashy. This is not negotiable.
Worth It?
Yeah. It is.
Pig Island isn’t going to blow your mind the way seeing Ang Thong at sunrise might. But it’s genuinely fun in a low-stakes, slightly absurd way — the kind of day where you’re standing on a beach in the Gulf of Thailand feeding pigs into the sea and you’re thinking how did this become my life.
For most people visiting Koh Samui, it’s a half-day well spent. Especially if you combine it with a snorkeling stop at Koh Taen, the day has real substance beyond just the novelty factor.
The Complete Pig Island Multi-Adventure Tour with Kayaking & Snorkeling packs a lot into one booking if you want maximum variety. Or if you want to keep it simple and just go swim with some pigs, the Koh Madsum Pig Island Adventure does exactly what it says.
Either way — go in the morning, bring fruit for the pigs, and don’t forget sunscreen.
