Exploring the Surin Islands by Speedboat from Khao Lak: A Complete Review
If you’re dreaming of a day spent floating above vibrant coral reefs, spotting sea turtles, and learning about Thailand’s fascinating sea nomads, the Surin Island snorkeling tour might catch your eye. While reviews show mixed experiences, there’s enough to love about this trip—especially if you’re a fan of marine life and remote islands.
What we love about this tour? First, the chance to explore untouched archipelago islands within Mu Ko Surin National Park, far from the crowds. Second, the opportunity to snorkel alongside clownfish, octopus, and sea turtles—a real treat for underwater enthusiasts. And third, the chance to meet the Moken Village, learning about the lives of Thailand’s sea nomads.
One thing to consider, however, is that water visibility and coral health may not meet everyone’s expectations, especially during times of bleaching or seasonal changes. This means that snorkelers expecting pristine conditions need to keep their hopes realistic.
This tour suits travelers who value authentic marine experiences, want to explore remote islands, and enjoy cultural insights into Thailand’s sea nomads. It’s ideal for those seeking a full-day adventure that combines nature, culture, and good food—all in a manageable group setting.

The Itinerary in Detail: What to Expect

Like underwater activities? Other Thailand snorkeling spots we've covered
Surin Islands: Nature’s Marine Showcase
The trip begins early with pick-up from your Khao Lak hotel, usually 30 to 60 minutes before departure. Once aboard the speedboat (a swift, comfortable ride that takes approximately 1.5 hours to reach the islands), you’ll be treated to scenic views of the Andaman Sea. As you approach the islands, the first impression is often of the white beaches and coral gardens that make Surin Islands a renowned diving and snorkeling spot.
The main islands—Ko Surin Nuea and Ko Surin Tai—are extremely close, separated by a shallow corridor. Here, the marine environment is vibrant, with coral reefs that have shown signs of recovery from bleaching events but may still vary in health and vibrancy. Many reviewers note that visibility isn’t always optimal. One reviewer commented, “The visibility was not excellent, and the corals are not in good shape,” which underscores the importance of managing expectations.
Snorkeling: Marine Life and Coral
Once anchored, you’ll gear up with provided snorkel gear—masks, fins, and life vests—and venture into the sea, where the underwater world is typically bustling with tropical fish, coral, and occasionally sea turtles. Expect to see clownfish, octopus, pipefish, and coral groupers, as highlighted in the tour description.
According to one review, the fish diversity was limited, and the coral was not in pristine condition, possibly due to environmental factors like El Niño-induced bleaching. However, many snorkelers still find plenty to marvel at, especially if you’re patient and love observing small creatures. The shallow coral gardens are accessible and safe for beginners, making this a good introduction to Thailand’s marine biodiversity.
Lunch and Snacks on Board
A major perk of this tour is the included buffet lunch, which is served on the boat. The Thai cuisine is hearty and flavorful, offering a good break after a few hours in the water. There are also snacks and soft drinks throughout the day, keeping you refreshed for the next activity.
Visiting the Moken Village
A unique highlight is the visit to the Moken Village, where you’ll learn about the lives of sea nomads who have traditionally traveled the Andaman Sea. Once settled on Koh Surin, the Moken community offers a fascinating glimpse into a lifestyle centered around the sea. One review mentioned how this part of the trip is “a rare cultural experience,” providing insight into a community that has maintained its traditions despite modern influences.
The village visit lasts about 45 minutes, and while it is free to explore, it’s a meaningful addition that enhances the tour’s cultural richness. Expect to learn about their history, lifestyle, and how they interact with the marine environment.

Transportation and Overall Value

The roundtrip transfers from Khao Lak resorts make this a hassle-free experience—no need to worry about how to reach the pier. The speedboat is fast and offers a fun, breezy ride that many find energizing. The cost of $175 per person includes virtually everything except additional drinks, making it a straightforward, all-in-one package.
While some reviewers mention that water conditions weren’t ideal, others appreciated the well-organized nature of the trip, including breakfast, lunch, and snacks, which add to the value. The tour is operated by I Asia Thailand, who maintain a good safety record, but always remember that sea conditions can vary, affecting your snorkeling experience.
Who Should Consider This Tour?
This trip is suited for adventurous travelers eager to explore Thailand’s remote islands and encounter marine life firsthand. It’s great for those who value cultural insights and are curious about the lives of Thailand’s sea nomads.
However, if your main goal is pristine coral and crystal-clear waters, you might find some disappointment since water conditions can fluctuate. It’s also ideal for families with older children (11 and up) and those comfortable with boat rides and water activities.
The Sum Up: Is the Surin Island Snorkeling Tour Worth It?

For travelers who want to experience an authentic, full-day adventure in Thailand’s lesser-visited waters, this tour offers a compelling package. You’ll get a taste of remote islands, diverse marine life, and local culture, all with the convenience of hotel transfers and included meals.

If you’re flexible about water conditions and eager to see the lives of Thailand’s sea nomads, this trip could be a memorable highlight of your Khao Lak adventure.
