A Snorkeling Day on Koh Tan and Koh Madsum – What You Need to Know
This tour takes you out from Koh Samui to explore two nearby islands: Koh Tan and Koh Madsum, with a focus on snorkeling, relaxing, and enjoying some of the best ocean views the Gulf of Thailand has to offer. For about $60 per person, you’ll spend roughly 6 to 7 hours out on the water—a good half day that balances adventure with downtime. The package includes hotel pickup, snorkeling gear, lunch, and soft drinks, making it a straightforward way to explore these lesser-visited islands without the hassle of organizing your own boat or transport.
What we appreciate most about this trip is how it caters to both snorkelers and relaxation seekers. The vibrant coral reefs at Koh Tan promise colorful underwater sights, and the beach on Koh Madsum, famous for its friendly pigs, offers a playful, laid-back vibe. We also like the hassle-free nature of the tour—round-trip transfers, included gear, and lunch help you focus on enjoying your day without worrying about logistics.
But, it’s worth noting that some reviews point out the size of the group and snorkeling quality can vary. For travelers craving a quiet, intimate experience or exceptional snorkel conditions, this may be something to consider. This tour seems best suited for those who want a full day of beach and reef exploration with convenient amenities included.
Who’s this tour perfect for? If you’re after a straightforward, well-organized day with opportunities to snorkel, relax on sandy beaches, and enjoy Thai food, this is a great option. It’s especially suitable for families, first-timers, or anyone who appreciates easy logistics and good value.

Exploring the Tour in Detail: What to Expect

When we first think about a day out on the water from Koh Samui, it’s the promise of scenic views and easy access to snorkeling spots that catch our attention.

Fascinated by underwater life? Here are other snorkeling spots we've covered in Koh Samui
The Speedboat Ride and Arrival at Koh Tan
Once at the port, you’ll board a speedboat, which traverses the Gulf of Thailand to reach your first stop: Koh Tan. The boat ride itself is quick and provides plenty of chances to enjoy ocean views and the breeze. As one reviewer pointed out, the ride is quick and pleasant, making it a comfortable journey that sets the tone for the day.
Koh Tan is especially popular for its coral reefs—a highlight for snorkelers. The tour includes snorkeling gear, so you can float over the vibrant underwater landscape. Keep in mind, though, that some reviews mention the snorkeling time is brief, with only about 45 minutes at Koh Tan, which might leave more avid snorkelers wanting more.
Koh Madsum and the Pig Island Fun
The next stop is Koh Madsum, affectionately called Pig Island due to the friendly, semi-wild pigs that roam the shores. Here, you get around four hours of free time, so you can relax on the white sandy beaches, take photos of the pigs, or try some kayaking if you’re feeling adventurous. The water is clear and inviting, making it perfect for a casual swim or just soaking up the sun.
Reviews rave about how cute and fun the pigs are, with one guest describing the island as “really nice.” It’s an ideal spot for families or animal lovers, or anyone who simply wants to unwind by the water.
Lunch and Resting Time
A Thai set menu lunch is included, served after the morning activities. The food is described as tasty, and the inclusive soft drinks and fresh fruit complement it well. Keep in mind, the lunch is served on the beach or near the boat, so you can enjoy authentic Thai flavors with ocean views. However, some reviews mention the buffet can be crowded and sitting in the heat, which might not appeal to those expecting a more refined dining experience.
Return Journey and Drop-off
After a relaxed afternoon, the boat heads back to Koh Samui, with the tour wrapping up around late afternoon. The drop-off at your hotel means you can skip the hassle of return transportation, leaving you free to continue exploring or relax after your day out.

The Experience We’ve Seen in Reviews
This tour has garnered mixed but generally positive feedback. Many reviewers highlight the helpful, friendly guides and the spectacular scenery. For example, one traveler mentioned that the views were great, and they even saw dolphins during their trip, adding a special touch to the experience.
On the downside, some guests found the snorkeling conditions less than ideal. One review noted, “there were no fishes,” and the snorkeling was very brief. It’s a reminder that marine life can be unpredictable, and the coral reefs, while colorful, may not be teeming with fish all the time.
The large group sizes—sometimes up to 40 people—have also been noted, which can diminish the feeling of intimacy and make the experience more crowded. Still, many appreciate the value for money and the smooth logistics.
Practical Tips for Making the Most of This Tour

- Bring a waterproof camera or phone case to capture the piglets and underwater sights.
- If you’re a serious snorkeler, consider whether the short snorkeling window suits your expectations.
- Pack some extra sunscreen and a hat, as the sun can be strong, especially on the beaches.
- Be prepared for potentially crowded beaches on Koh Madsum; arriving early can help secure a good spot.
