The Tan Bok Khorani Island tour reviewed was arranged through a local operator on Pasai Beach on Koh Yao Noi’s eastern coast. The tour takes in a group of islands that would be impractical to reach in a day from either Phuket or Krabi except by speedboat. However it is comfortable to reach by long-tailed boat in around 4 hours from Koh Yao Noi allowing enough time to spend time on the islands. The main islands are Koh Phak Bia, Koh Lao La Ding and Koh Hong. The tour allows time for swimming and snorkling.
