Starting the Day: From Your Hotel to the Islands

The tour kicks off with a pick-up from your Koh Lanta hotel—either directly from your beach resort or from the lobby, depending on location. The operator offers a modern, spacious speed boat that comfortably fits small groups, an important detail that keeps the experience intimate and less crowded than larger boats. The boat boasts both outdoor and indoor spaces, a clean toilet, and top-notch safety gear, including life jackets and modern navigation equipment.

Travel time from Koh Lanta to Koh Rok is under an hour, making it a smooth and quick ride that helps you shake off any initial travel nerves. Several reviews mention how the boat crew, particularly guides like Leo, make the ride enjoyable with friendly chatter and safety briefings. Keep in mind that speedboats, by nature, can be a bit bumpy—so if you’re worried about seasickness, bringing medication or motion sickness bands might be a wise idea.

Exploring Koh Haa: Lagoon Paradise and Snorkeling

The first major stop is Koh Haa, a group of five small islands famous for their mini lagoons and abundant marine life. You’ll have about an hour here to snorkel in crystal-clear waters that often boast visibility of several meters, revealing coral gardens teeming with colorful fish and sea creatures. Reviews highlight that guides like Ja and Shoot are particularly helpful, ensuring everyone, including less confident swimmers, feels safe and included.

Many travelers mention that the underwater scenery at Koh Haa is spectacular—“fantastic snorkeling,” as one reviewer puts it, with plenty of fish and coral to admire. A tip from the reviews: bring a waterproof camera or GoPro to capture the vibrant marine life. The shallow coral channels, sometimes just a few meters below the surface, are perfect for novice snorkelers, but don’t forget your waterproof case.

Koh Rok: Idyllic Beaches and Coral Reefs

After a scenic boat ride, you’ll arrive at the Koh Rok Islands, which consist of Koh Rok Nai (closer to the mainland) and Koh Rok Nok (the outer island). Separated by a 250-meter coral channel, these twin islands are protected as part of Mu Ko Lanta National Park, ensuring their pristine condition.

Your first stop is Koh Rok Yai Beach, where you’ll have about an hour for swimming, strolling along the long white beaches, or even hiking up to Pha Samed Daeng, a viewpoint offering sweeping views of the surrounding islands. The reviews frequently mention the beautiful beaches and how relaxing it is to walk on the soft sand or wade in the shallow waters.

Next, snorkelers will enjoy a dedicated hour exploring more coral reefs and marine life. The reefs here are shallow, often less than five meters deep, making it an excellent opportunity to see a kaleidoscope of fish and corals. Many reviews praise the guides for taking guests to the “best spots,” ensuring you see the highlights without wasting time.

Lunch and Leisure on Koh Rok Nai

A highlight of the trip is the buffet Thai lunch on Koh Rok Nai, served on a lovely beach setting. The food is well-reviewed—fresh, flavorful, and plentiful, with many guests noting that they returned to the boat well-fed and happy. This break allows some to relax on the beach, swim, or explore the shoreline further.

For those feeling energetic, there’s also an opportunity to hike to a viewpoint or take a leisurely walk along the sands. The guides often encourage a bit of exploration, making the island feel like a private hideaway.
