Koh Yao Yai
Coastal scenery, unhurried island days and a choice of resort bases in Phang Nga Bay.
Where in Thailand
The feel of the place
A quiet island stay with village life and substantial resort options.
Koh Yao Yai combines quiet coastal stays and village outings with several substantial resorts. Choose your base carefully: the island is spread out, and beach character changes with location and tide. Boat arrival, on-island transport and excursion arrangements are separate parts of the stay.
Keep in mind
The island is dispersed, beaches are tide-sensitive, and a resort transfer does not provide effortless transport everywhere else.
