Koh Samui Airport
The closest airport is Ko Samui (USM) which has frequent flights from Bangkok, Phuket and Singapore, and several direct flights each week from Chiang Mai and Kuala Lumpur. Transportation to the ferry dock is easy to find at the airport. Ferries depart several times a day with the last one around dusk. Flights to Ko Samui are much more expensive than to Chumphon or Surat Thani.
