Transport Fair Pricing Guide for Koh Samui

Metered taxis in Koh Samui operate on a regulated fare structure set by Thailand's Land Transport Department: the flag fall is 35 THB for the first kilometer, then 5.5-10.5 THB per kilometer depending on distance, plus a 2 THB per minute surcharge when stationary in traffic. A typical ride within the main tourist area of Koh Samui costs between 100-300 THB, while airport transfers range from 200-500 THB depending on distance. Always insist the driver turns on the meter before starting the journey — if they refuse, exit and find another taxi, as meter refusal is illegal and typically results in a 2-3x markup. For the most transparent pricing, use ride-hailing apps like Grab or Bolt or inDrive, which show the exact fare before you confirm the ride and provide GPS tracking. During rush hours (7-9 AM and 5-8 PM), surge pricing on apps may make metered taxis cheaper.
