Trading the turquoise Gulf of Thailand for the misty mountains of the north is one of the most rewarding switches you can make in Thailand. Koh Samui is all salt air and coconut groves; Chiang Mai has a different rhythm of temple spires, artisan coffee shops and cool highland evenings. The trip takes you from the island coast to the cultural heart of the north, across almost the whole length of the country.
With a long distance and a sea crossing between them, this is a trip to fly. Compare the flight options on GoAsia.cc to make the move from beach to mountains as smooth as possible.
Koh Samui to Chiang Mai by Flight
Flying is the practical choice. Samui Airport is a charming departure point, a set of open-air pavilions built with wood from coconut palms,[1] and at the other end Chiang Mai's Old City is a short taxi ride from the airport.

- Book Early: Seats on the direct flight are limited, so book at least a few weeks ahead for the best fares.
