After morning pickup 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, disembarking and heading for the panoramic viewpoint 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. Afterwards, head to the pristine beaches to unwind and relax before heading back to Koh Samui.
