Ko Samui is served by Samui International Airport (USM), a privately owned airport located approximately 2 km north of Chaweng, the island's main tourist hub. The airport sits about 4 km from Nathon, the administrative center of the island. Airport transfers to city center destinations on Ko Samui are straightforward, with options including taxis, shared minivans, songthaews (local pickup trucks), private transfers, and rental cars. Journey times are generally short due to the compact size of the island, though travel times can vary depending on your final destination and traffic conditions.
