The Experience

The day starts with hotel pickup and a boat ride out to the marine park. Once you arrive, you'll snorkel in the warm Gulf waters where the reefs hold tropical fish and the visibility lets you see the limestone formations below. The guide handles the route and timing, and all snorkeling gear and a life jacket are provided—you bring only swimwear and a camera in a waterproof case.

Ko Mae Ko is the centerpiece stop. The island has a sandy beach and an inland saltwater lake called the Emerald Lagoon (Thale Nai), which you reach by climbing wooden stairs and pathways up a nearby mountain. The climb takes you to a viewpoint 400 meters high that overlooks the whole park. After that, you have time to swim in the crystal-clear water or rest on the beach before lunch arrives.

Thai buffet lunch happens on Wua Ta Lap Island, the park headquarters. The afternoon is yours to choose: relax on the tranquil beach, sunbathe, swim again, or hike to the high viewpoint if you skipped it earlier. Sea kayaking happens throughout the day as part of the route between islands. The tour runs 8 to 9 hours total. Weather and sea conditions can shift the itinerary, and the park shuts down every year between November 1 and December 15 during monsoon season.
