Getting to Koh Samui
Flying to Koh Samui: Samui Airport is privately owned by Bangkok Airways, making it one of the more expensive places to fly in Thailand. There are many flights to Bangkok, Krabi, and Phuket every day, as well as limited international flights to Malaysia, Hong Kong and Singapore.
The airport is 2km from Chewang Beach and a taxi will cost approx 400 baht. If you are travelling to Lamai, expect to pay 700 or to Maenam 600 Baht. A private minivan transfer is about 25% more. Alternatively, you can book a private transfer.
Ferries to Samui: Many travellers arrive in Samui by ferry. There are two main ferry piers on the island: Nathon (Seatrans and Lomprayah), and Lipa Noi (Raja Ferry Pier) and both on the western side of the island. Ferries leave hourly between 5 am and 6 pm or 7 pm. Along with passenger ferries, two car ferries operate from Don Sak Pier in Surat Thani on the mainland.
Getting around Koh Samui
Getting around Koh Samui: Koh Samui is easy to navigate by rental car or bike. A 51km long road runs in a circle around the island, making it very hard to get lost! This road is in good condition and traffic is quite manageable for experienced drivers. If you plan to drive, make sure you get an international driver’s license in your home country before you leave.
At its widest point, Koh Samui measure 25 kilometres (16 mi).
If you want to rent a motorcycle, you must have a motorcycle license in your own country. The police do book people who do not have one and your insurance will not cover you on a motorbike if you are not licensed.
There is no public bus service in Samui, nor are there Tuk Tuks. There are taxis (that rarely use the meter). However, most visitors use the Songthaews (pronounced song-tao), which operate fixed rates (approx 40-100 baht) during the day. In the evening, prices need to be negotiated as they are with Tuk tuks in other parts of the country.
