Ring Road Orientation: Everything Is Described by Coast

Almost all life on Samui sits along a single ring road, Route 4169, which loops the coastline for roughly 51-55 km. The mountainous interior has very few roads. Because of this, nobody navigates by street names; places are described as 'north coast', 'east coast', 'south of Lamai' and so on. Driving the full loop without stops takes about 1.5 to 2.5 hours depending on traffic. A useful mental map: Nathon (main port and capital) is on the west coast; the airport and Big Buddha are in the northeast; Chaweng and Lamai are the busy east coast beaches; Bophut, Bangrak and Maenam are on the north coast; the south and southwest (Hua Thanon, Taling Ngam, Lipa Noi) are the quietest.
