The island is just 25 km long and 21 km across, so it doesn’t take long to get anywhere. There are no tuktuks or buses in Samui, and no scheduled public transportation. Below please see options for getting around.
Private Taxi/Van
There are many private vans and people carriers that can pick you up at the airport, or any other location on the island, arranged in advance. Cost from airport to almost anywhere on the island should be about 500-600 baht

Songthaew
SongThaews (2 rows) are covered pick-up trucks with 2 benches in the back that you can hop on/hop off. They basically circle the ring road (the main circular road around the island which is 51 km). There are no predetermined routes or schedules. If you want to catch a songthaew, just go at the main road and flag one. When it stops, talk to the driver and tell him your destination. Depending on how much you are willing to pay, the driver can even take you to off-route destinations. When it’s time to get off, just ring the bell inside. Prices should start at 50-80 baht. Always determine the price in advance. They can take your luggage also. They are currently not allowed to enter the airport arrivals, but if you walk a few minutes out from the airport gate to the street, you will find one.
Public Taxis
There is only 1 taxi company on Samui, so prices are not competitive. It is fairly easy to flag one from the main road, or at any major tourist zone. Look for yellow & maroon cars. Even though the taxis have meters, few drivers use them. Before getting in the taxi, make sure to ask the driver to set the meter. If he refuses, negotiate a fixed rate for your route. Most trips begin at 500 baht.
Wear a Helmet!
Koh Samui is a tropical island, but it still sees scooter accidents every day, often caused by heavy rains and sand on the streets. Thailand has helmet laws in place that require all motorbike riders and passengers to wear helmets that meet safety standards. Failure to comply can result in legal consequences, including fines, penalties, and even imprisonment. Please check your travel medical insurance to make sure there is not a rider against any accident arising from being on a scooter/motorcycle.
