Koh Samui Islands Snorkeling Trip By Speedboat: A Practical Dive into Island-Hopping and Marine Life

Starting your day around 10:00 am, this full-day adventure whisks you away on a brightly colored longtail boat to explore some of the most serene islands off Koh Samui’s south coast. For just $56.78 per person, you’ll get roughly 6 hours of time filled with snorkeling, relaxing, and soaking in breathtaking views. The trip takes you to Koh Tan, known for its coral reefs and tropical fish, and Koh Madsum, a quieter island with beautiful beaches and a luxury resort.
We particularly appreciate that this tour offers hotel pickup from multiple locations — Lamai, Chaweng, Maenam, Bophut, and others — making it a practical choice for travelers staying in different parts of Koh Samui. The inclusion of lunch, drinks, snorkeling gear, and accident insurance adds value, making it a worry-free experience.
However, a key consideration is the minimum group size of 10 travelers required to run the tour, which might be a concern if you’re traveling during low season or solo. Also, some reviews suggest that the snorkeling spots may not be as spectacular as expected — one reviewer felt it was more about the island stop than the snorkeling itself. This tour suits travelers who enjoy quiet beaches, gentle snorkeling, and seeing less-touristy islands rather than those seeking thrilling underwater adventures.

A Detailed Look at the Koh Samui Islands Snorkeling Trip

The Itinerary and What to Expect
This trip begins with a pickup from various Koh Samui locations, ensuring you avoid the hassle of self-arranging transportation. Once aboard the colorful longtail boat, you’ll cruise across the turquoise waters toward the first stop, Koh Tan. This island is renowned for its protected reefs, which host giant clams, vibrant coral, and tropical fish.
Snorkeling here is a highlight — or at least it should be, depending on your expectations. One reviewer, Norman, pointed out that while the crew was friendly, the snorkeling was limited to a single, somewhat underwhelming location for about an hour. This suggests that the main appeal might be the island scenery and beaches rather than multiple snorkeling spots.
After some relaxing time on Koh Tan, the boat heads south to Koh Madsum, famous for its long, white sandy beaches and a luxury resort. This island provides an ideal setting for a picnic, sunbathing, or gentle walks along the shore. The local vibe is tranquil, making it perfect for those seeking a peaceful escape rather than a bustling tourist scene.
Snorkeling and Marine Life
The snorkeling gear—including masks and life jackets—is supplied, making it easy to hop into the water. You’ll likely see colorful fish and coral, though the quality and variety depend heavily on the day’s conditions and specific snorkeling spots. The tour’s focus on secluded reefs offers a chance to see marine life away from crowded tourist areas, which many travelers find refreshing.
As Michael noted in his review, the equipment was good, and the pickup process worked flawlessly. These small comforts can make a significant difference when you’re on a day-long trip, reducing stress and maximizing your enjoyment.
The Beach Relaxation and Sightseeing
The main attractions are the white sandy beaches on Koh Madsum and Koh Tan, where you can lie back and soak up the sun or take leisurely walks. The views over the Gulf of Thailand are stunning, especially when the boat is anchored, and you gaze out over the calm, turquoise sea.

Food and Drinks

You’ll also enjoy soft drinks, water, cola, and fresh fruit, all of which help keep you refreshed during the day. This inclusion adds good value, especially since some similar tours charge extra for meals.
Who Is This Tour Best For?
This trip is ideal for relaxation seekers, families with children (ages 4-11), and those who enjoy quiet beaches and gentle snorkeling. It’s less suitable for adventure snorkelers or those craving multiple reef stops — as one reviewer pointed out, the snorkeling may be more modest than expected. Also, if you’re looking for a fast-paced, adrenaline-filled day, this tour might feel a bit mellow.
What Travelers Are Saying

The reviews paint a balanced picture. Norman appreciated the great crew but was disappointed that the snorkeling was limited and felt the trip was more about the island stop than underwater exploration. Conversely, Michael found it to be a “beautiful day on the water” with well-organized pickup and supplied snorkeling gear that met expectations.
This split opinion highlights that your experience depends heavily on what you hope to get out of the day. If you’re after peaceful beaches, scenic views, and simple snorkeling, you’ll likely enjoy this trip. But if your priority is snorkeling at multiple vibrant reefs, you might want to consider other options.
The Practical Side: Price, Duration, and Considerations

At roughly $56.78 per person, this tour offers good value considering the included hotel transfers, lunch, drinks, and snorkeling gear. The 6-hour duration allows ample time to enjoy the islands without feeling rushed, especially since the trip is well-paced with stops for relaxation and sightseeing.
Keep in mind that minimum group size is 10 travelers, so it’s best to book in advance—especially during peak season, when this trip is often booked about 49 days ahead. The weather can impact the trip — poor weather might lead to cancellation with a full refund if booked through a flexible provider.
If you’re traveling with children, note that kids aged 4-11 are eligible for child tickets, making it a family-friendly option. However, pregnant women, guests with high blood pressure, heart disease, or bone issues are advised against participating, for safety reasons.
Who Should Consider This Tour?

This adventure is perfect for those wanting a relaxing day on the sea, exploring secluded islands that are less crowded, and enjoying simple snorkeling with all essentials covered. If your idea of a good day involves lounging on pristine beaches, spotting marine life, and indulging in authentic Thai lunch in a peaceful setting, this trip fits the bill.
However, if you’re after more vibrant reefs or multiple snorkeling stops, or if you prefer fast-paced water activities, you might want to explore other options.
The Sum Up

In essence, the Koh Samui Islands Snorkeling Trip by Speedboat offers a peaceful, scenic escape to off-the-beaten-path islands. It’s a well-organized option for casual snorkelers, beach lovers, and families looking for a relaxing day with included amenities. The secluded beaches and calm waters make it an excellent choice for unwinding, while the limited snorkel spots keep expectations realistic.
If you’re seeking a gentle, scenic cruise with easy access to beautiful beaches and coral reefs, and don’t mind a slower snorkeling pace, this tour is a worthwhile addition to your Koh Samui experience. Just remember that the quality of snorkeling depends on the day’s conditions, and the main draw may be the quiet islands and scenic views rather than spectacular underwater reefs.
