Chiang Mai is tourist-oriented, and it is therefore relatively easy to get around, with several transport options. Three-wheeled tuk tuks, also known as samlors, are usually the quickest means of transport, and fares should be negotiated before travelling. Songthaews are another novel (if slightly hair-raising) way to travel. Songthaews are small, usually red, pickup trucks with benches fitted along the side; they have no fixed route but pick up and drop off passengers like buses and need to be flagged down. Passengers should be sure to check the destination with the driver. The Chiang Mai bus service is very limited; catching a metered taxi can also be difficult at times. Renting a motorbike is a popular option, and car rental agencies are also available, though traffic can be heavy, and it is advised to rather hire a car with a driver. Bicycles are another good way to explore Chiang Mai and can be hired in the old city, though travellers will have to watch out for other drivers.
