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.
