The Latest Tour's Guide to Bangkok & Thailand has a bus map of Bangkok on one side and a fair map of Thailand on the other, and is usually priced at around 30 Baht. The bus map is quite necessary if you intend to spend much time in Bangkok and want to use the very economical bus system. It is available at most bookshops in Bangkok that carry English-language materials. A better map of the country is published by APA Productions which costs around US$7, also available at many Bangkok bookshops, as well as overseas.
Even better is the four-map set issued by Thailand's Department of Highways? For 65 Baht you get a very detailed road map of the central, northern, northeastern and southern regions. The maps include information on 'roads not under control by the Highway Department'; for example, many of the roads you may travel on in the Golden Triangle. Bookstores sometimes sell this set for 200 Baht, including a mailing tube, but the Highway Department on Si Ayutthaya Road and the Bangkok Tourist Authority of Thailand office on Ratchadamnoen Nok offer the set at the lower price. The mailing tube is not worth 135 Baht.
Recently DK Books has published a 44-page bilingual road atlas called Thailand Highway Map that has cut the highway department maps to a more manageable size and includes dozens of city maps, driving distances and lots of travel and sightseeing information.
The Highway Department maps are more than adequate for most people. At DK Books in Chiang Mai, however, you can also purchase Thai military maps, which focus on areas no larger than the amphur (local district), complete with elevations and contour lines. These may be of use to the solo trekker, but cost 60 Baht upwards per map. DK also publishes special maps for hill-tribe trekkers.
There are also Nancy Chandler's very useful city maps of Bangkok and Chiang Mai, which are actually more than just maps. Her colourful maps serve as up-to-date and informative guides, spotlighting local sights, noting local markets and their wares, outlining local transport and even recommending restaurants.
