Samui International Airport, also known as Ko Samui Airport or Koh Samui Airport, is a privately owned airport on the island of Ko Samui (Koh Samui) in Thailand. The airport is located roughly 2 km north of the main city and largest resort centre on the island, Chaweng. It was built by Bangkok Airways; construction began in 1982 and the airport was officially opened in April 1989. Samui Airport is an unusual airport because there is no indoor area, except the gift shop. Notwithstanding it is the country’s sixth busiest airport handling more than a million passengers annually. The airport has two terminals (Domestic & International). The International terminal is located about 50 metres north of the domestic. Samui Airport is located near the Big Buddha Pier where ferries depart to Ko Pha Ngan. High speed ferries to Koh Tao and Chumphon depart from the Maenam Beach Pier, approximately 6 km north-west of the airport.
