One of Thailand’s unseen highlights, this amazing natural phenomenon is set to take place at Chicken Island (Koh Kai or Koh Daam Kwan), when tides change dramatically in different hours of a day.
When the tide is low, it reveals a white sand dune and limestone beach connecting three islands together. You can walk across from Chicken Island to the other two islands at low tide. If so, it should be in the lowest tide of the day.
Glide across the Andaman Sea on a traditional long tail boat, stopping at top snorkelling spots and unspoiled beaches. The route is full of unusual natural features, like a disappearing sandbank, a chicken-head rock formation, and underwater tunnels that you can swim through (Depending on the season, high tide and safety).
