Town Overview

Life in Koh Samui

Island beaches come with an airport, hospitals, schools and an established international community on Koh Samui. It has far more everyday infrastructure than a remote island escape, with island costs to weigh.

The Appeal

Koh Samui is a green granite island of palm-fringed bays, fishing villages and forested hills, with international schools, private hospitals and an airport with direct flights to Bangkok, Singapore and Hong Kong.

Why It Made the Shortlist

Koh Samui is the only island option in this Atlas on the Gulf side, away from the Andaman tsunami coast, in the lowest regulated seismic band. It took eighth place when Chanthaburi failed the border-security screen.

Worth Knowing
  • Flights are expensive, from an airport owned by one airline.
  • A 2026 water shortage brought island-wide rationing.
  • The late-year monsoon is heavy.
  • Hillside building is limited.
  • Serious medical cases are sent off the island.
Getting There
  • Samui Airport is about 1 hr 5 min from Bangkok by air.
  • Or fly to Surat Thani and take the car ferry from Don Sak, about 1 hr 30 min at sea.
