Start with pickup at your hotel on Koh Phangan and transfer to Thong Sala Pier in a climate-controlled minivan. Head to Mu Koh Angthong National Park by speedboat, where the first stop of the day is a snorkel spot at the base of sheer limestone cliffs.
Continue to Mae Koh Island to paddle along the coastline in a sit-on-top kayak, then pause for a Thai-style buffet lunch near the marine park ranger station. Spend the early afternoon soaking up the paradise-island atmosphere on Mae Koh, with time to swim, snorkel, or sunbathe on the island’s white-sand beaches.
The final stop of the day is just a few minutes from Mae Koh by speedboat. A short hike up an island trail will earn you views of the Emerald Lagoon, or Talay Nai, a saltwater lake that’s surrounded by limestone cliffs and thick tropical forest. After the hike to Emerald Lagoon, begin the return trip to Koh Phangan by speedboat. This tour concludes with drop-off at your hotel.
