Imagine slipping away from the crowds, gliding on a traditional longtail boat, and finding yourself on islands so unspoiled that they seem like private escapes. That’s pretty much what this Koh Samui Secret Islands boat trip offers—a chance to explore hidden corners of the Gulf of Thailand in small, intimate groups. It’s a full six hours of adventure, relaxation, and discovering nature’s quieter side.
What makes this tour stand out? First, its focus on small-group intimacy (usually 10-12 people), which makes every experience more personal and less rushed. Second, the chance to visit two secluded islands, Koh Mudsum and Koh Tan, away from the typical tourist trail. Third, the affordable price point—offering great value compared to other operators with similar itineraries.
A small potential consideration? Since the trip involves uninhabited islands with basic amenities, it may not be ideal for travelers seeking all-inclusive comforts or modern facilities. Also, it’s not suitable for pregnant women, babies under 1 year, or those on cruise ships.
This tour best suits those who love authentic, off-the-beaten-path experiences, enjoy snorkeling and beach lounging, and want a day away from crowded tourist spots. It’s perfect for adventure seekers, nature lovers, and budget-conscious travelers who want a genuine island-hopping experience.

Why You’ll Love the Koh Samui Secret Islands Boat Trip
This experience is designed for those wanting to escape the busy tourist crowds and discover the quiet, natural beauty of nearby islands. We loved the way the tour balances adventure and relaxation, making it suitable whether you’re looking to snorkel, stroll pristine beaches, or simply soak in the scenery. The small group size means you won’t feel lost in a crowd, and the boat ride in a traditional longtail boat adds an authentic Thai touch.
The tour’s highlight is visiting Koh Mudsum, an uninhabited island with white sandy beaches and no modern developments—think “deserted island,” with a cute addition of woolen pigs lounging on the sands, as one reviewer humorously noted. It’s a quirky, memorable sight that makes you feel like you’ve stumbled onto a secret paradise.
Another major plus? The snorkeling experience. With free gear provided, you can explore the underwater world in calm, clear waters. Reviewers mention the potential to see rare sea creatures, which adds a layer of thrill to the trip. The second island, Koh Tan, offers a lush mangrove forest walk or beach relaxation, catering to different tastes.
The lunch spot deserves special mention. Situated directly on the white sands, the restaurant serves a delicious, freshly prepared Thai meal with views that make it hard not to take endless photos. Since the menu is described as varied and not overly spicy, it’s accessible for most tastes.
And after spending time on Koh Tan—whether swimming, snapping photos, or relaxing—you’ll head back in the boat, with the option to linger longer on the beach or take memorable photos on swings. The return journey and pickup/drop-off are smooth, with transfers included to make logistics effortless.

The Itinerary: What You Can Expect
Starting early around 7:45-8:30 a.m., the tour kicks off with a pick-up from your accommodation in an air-conditioned minibus. This is a nice touch, as it saves you the hassle of finding your way to the harbor. The group then heads to Thong Krut pier, where the traditional longtail boat awaits. The 30-minute boat ride is part of the charm—slipping through calm waters, feeling like part of a local scene rather than a tourist.
The first stop is Koh Mudsum, an island with starkly white beaches, no electricity, and a small restaurant. Here, the highlight is the woolen pigs, which might remind you of the Bahamas, but with a uniquely Thai twist. It’s a quiet spot, perfect for photos or just soaking in the peaceful vibe.
Next, the boat moves to Koh Tan for snorkeling. Floating in the calm waters with free gear, you’ll get a chance to see vibrant corals and maybe even some rare fish. One reviewer mentioned the underwater life as being “eventful,” hinting at a lively reef just beneath the surface. The boat then anchors in front of Koh Tan for exploration—walking through mangrove forests or relaxing on the deserted beaches.
Lunch is served at a small beachside restaurant, with regional Thai dishes that balance flavor and spice levels. The view of the Gulf of Thailand adds to the enjoyment, and the relaxed pace allows for lingering before heading back.
The final part of the day is free for more swimming, relaxing, or taking photos on the swings. The boat then makes its way back, arriving at Thong Krut pier around 2:30 p.m., followed by a smooth drop-off at your hotel.
Transportation, Timing, and Group Size
The tour uses a comfortable air-conditioned minibus for the pick-up and drop-off, making the start and end of your day hassle-free.

The entire tour lasts about 6 hours, with flexible starting times depending on availability.

The Value of the Experience
Compared to other similar tours, this one offers excellent value. Its lower price point doesn’t mean skimping—snorkeling gear, a freshly prepared Thai lunch, and small-group comfort are all included, making it a comprehensive package. For travelers who want quality without paying a premium, it’s a smart choice.
The emphasis on off-the-beaten-path islands means fewer crowds and more authentic landscapes. If you’re after picture-perfect beaches, quiet snorkel spots, and the chance to see local wildlife like woolen pigs, this trip ticks all those boxes.
