TIP
Select a pickup point
After a morning pick-up from Koh Samui, head straight to the pier to begin your maritime excursion among the 42 islands of Ang Thong. After being fitted for masks and snorkels, you’ll glide over to the island of Koh Wao to snorkel in the crystal-clear waters among magnificently diverse coral reefs. Explore the sheltered bay, keeping your eyes peeled for tropical fish. Continuing through the national park, you’ll arrive at Koh Mae Ko for kayaking and after that. Disembarking and heading for the panoramic view above the Emerald Lagoon, a gem of Ang Thong Park. Fed by the sea through a series of caves, the lagoon is completely untouched, as it is illegal to swim within it. Afterward, head to Koh Phaluai for a seaside Thai lunch, and for some time to unwind and relax on the beach before heading back to Koh Samui

The trip was planned well but execution on ground lacked. It lets you move from island to island with picturesque sights. However the staff looks to be in hurry and doesn’t give a friendly vibe especially if you are with kids.

Great experience, got to do several activities and see Ang Thongs beauty. Guides were friendly and helpful. Boat was clean and they had snacks to keep us from going hungry throughout the day.

Visiting the Ang Thong Marine Park is a must if you are in Koh Samui and this is the ONLY way to do it. Our captain, Saw, kept us informed, comfortable, and safe, the equipment was pristine, and the small group size enabled us to really fully enjoy our time and experiences on the various islands in the park. We were pampered by the entire crew with fresh fruit, cold drinks, fresh water rinses coming from the water back to the boat, and helping with all the equipment and gear needed for the various activities. From seeing dazzling schools of fish to monkeys in trees to a wonderful lunch in a fishing village, the day is full of fun and amazement. Do not miss this!
