Samui is an explorer’s dream to discover something new. Offering a wealth of diversity of landscape, vistas, flora and fauna, and yet small enough to seek adventure in its many out-of-the-way places, Samui can be seen by taking songthaews (red open back jitney) which operate around the island. The fare starts at 50 baht, depending on the distance of the destination.
Taxi say "Taxi meter" but they do not turn on the meter. Prices are dictated by the driver. More expensive at night. If the driver will not give you a fair price wait for the next one, or take the
songthaews (red open back jitney). Songtthaews are cheaper than taxis but will stop for other passengers along the way.
By a Rented Jeep or Rental Car
Rented Jeep, 4WD, or standard Rental Cars are available from many family-owned agencies and some well known large companies.. Some of these vehicles come with insurance, some not. Always ask for details first. The minimum price start from 900 baht.
A more flexible way to get around the island, a rented motorcycle costs approximately 200 baht per day. Beware, as some roads other than the main roads on Koh Samui are quite rough.
So be very careful on a motorbike. Many fatal accidents occur every year.
