Travelling within Chiang Mai

From Airport, Train and Bus Terminal to town
There is a licensed airport taxi service available at the taxi kiosk outside the baggage-claim area. Purchase a ticket and present it to the drivers waiting by the arrivals exit area. The trip will cost approximately 100 bahts for a sedan car that seats 4-5 people (with luggage).
From the airport, train station and bus terminal, you can easily get a song taew (red mini-bus). To charter a minibus or car, please check the correct fare at the TAT counter first.
Normally, first-class hotels provide complimentary transportation between the airport, railway station or bus terminals and the hotel for guests who have made advance reservations.
Short-distance travel

1. For relative short distances you can take a sam lor or tuk-tuk (a tricycle). Fares must be bargained in advance. Short rides within the city costs between 20 and 30 bahts. Longer rides may cost as much as 50 bahts.

2. Just new in town is the taxi-metre, the same as those running around Bangkok. The minimum (starting) fare is 35 bahts.

3. Song taew (red mini-bus) is the most common means of transportation in town. Passengers can hop in and out as they wish. Simply tell the driver the destination and negotiate the price before boarding. Fares range from 10-20 bahts depending on the distance.

4.Bicycles
Some travelers prefer to ride a bicycle around the city as most of the roads and alleys are accessible by bicycle. Bicycles can be rented from bicycle shops and certain guesthouses.

5. Chiangmai Bus
Chiang Mai's on-again, off-again local bus service began operation again in November 2005. There are currently 5 routes and fares are a flat 15 baht. Route 4, connecting to the airport, is probably the most useful
