Snorkel Adventure Sea Tour to Koh Rok and Koh Haa from Koh Lanta

Starting from Koh Lanta, this seven-and-a-half-hour day trip whisks you away to some of the most breathtaking snorkeling spots in Thailand’s Andaman Sea. For just over $53 per person, you’ll visit two uninhabited islands—Koh Rok and Koh Haa—and explore coral reefs teeming with marine life. Your day includes hotel pickup, a comfortable speedboat ride, multiple snorkeling stops, and a delicious Thai buffet lunch on the beach.
We love how organized and smooth the experience feels, with hotel transfers that eliminate the fuss of finding meeting points. The knowledgeable guides often go the extra mile—one of the reviews even mentions a guide (Tay) who was so friendly he wanted to hold a customer’s baby so they could snorkel together. The boat itself is modern, spacious, and equipped with safety gear, making the journey as comfortable as it is exciting.
A couple of considerations: the boat ride can be bumpy, especially if the weather isn’t cooperative, which might bother those prone to motion sickness or with back issues. This trip is perfect for active snorkelers and families who want a reliable, well-organized day exploring some of Thailand’s quieter and more pristine marine environments.
If you’re someone who values expert guidance, hassle-free logistics, and stunning underwater scenery, this tour offers excellent value and memorable sights.

An In-Depth Look at the Snorkel Adventure Sea Tour
Overview and What to Expect
This tour offers a comprehensive day out that balances snorkeling, beach time, and some well-earned relaxation. It’s designed to show you the best underwater sights while making sure the logistics are effortless. Starting early with pickup from your Koh Lanta hotel, you’ll be whisked away by a modern speedboat with indoor and outdoor seating, a clean toilet, and safety equipment. The crew is trained in first aid and CPR, which provides peace of mind throughout the day.
The experience is packed with four main stops: the lagoon of Koh Haa, the twin islands of Koh Rok, a snorkel in the channel between them, and a relaxing lunch on Koh Rok Nai. Each stop offers something unique—whether it’s the spectacular underwater coral reefs or the long white beaches perfect for strolling or sunbathing.
The Itinerary in Detail
Start at Saladan Pier: Depending on your accommodation, you’ll either be picked up directly on the beach or via car. The speedboat departs around 9:00 am, heading toward Koh Haa, which is a highlight for many thanks to its stunning lagoon made up of six rocky outcrops. One reviewer called this stop a “feature” of the trip, noting the crystal-clear waters and abundant marine life in the lagoon.
Koh Haa Lagoon: Expect to snorkel among schools of fish and coral in what many consider a “swimming in an aquarium” experience. The shallow waters make it accessible, and the vibrant marine ecosystem is well-protected, ensuring you see plenty of marine life without fighting currents or wind.
Koh Rok: The twin islands—Koh Rok Nai (closer to the mainland) and Koh Rok Nok—are considered some of the most beautiful islands in the area. Separated by a coral channel just 250 meters wide, they feature white sandy beaches and coral reefs less than 5 meters beneath the surface. Snorkelers will find plenty of colorful fish, coral formations, and possibly even land monitor lizards wandering around.
Lunch on Koh Rok Nai: A Thai buffet served on the beach offers a relaxing break. One review mentions the delicious and simple meal, with some describing it as “tasty,” making it a perfect way to refuel. Afterward, you’ll have time to walk along the beaches, enjoy the scenery, or ascend a trail to the Pha Samed Daeng viewpoint for sweeping northern vistas of Koh Ngai and Koh Lanta.
Final snorkeling and return: The last stop on Koh Rok Nai allows for more underwater exploring before the boat passes by the Koh Rok Waterfall—albeit briefly. The return trip to Koh Lanta is about an hour, with some noting the ride can be rough in windy conditions. The boat is fast, which is great for covering the distance quickly but can lead to a bumpy ride.
What Travelers Say
Many reviews highlight the well-organized nature of the trip. As one reviewer notes, “We received a message a few minutes after booking with pickup info. They were on time and very friendly.” The guides, especially Tay, are praised for their friendly demeanor and willingness to help, sometimes even engaging children or holding devices like GoPros for better underwater shots.
Snorkeling spots garner high praise for clarity and marine diversity. One traveler described the underwater scenes as being akin to “swimming in an aquarium,” with vibrant fish and coral that made the experience unforgettable. Several reviews mention the abundance of colorful fish, including clownfish, which are always a hit.
The lunch gets consistent positive feedback, with many describing it as simple but tasty. The location on Koh Rok Nai’s beach provides a peaceful, scenic setting that complements the underwater adventures perfectly.
