Bangkok can be an overwhelmingly large and confusing city for the uninitiated. This is why carrying a map of the city is essential for travellers. Make sure the map you have on hand is up to date as road names, expressways and other designations often change names in Bangkok and most guidebooks will not be able to encompass all of these changes. Finding a map with English and Thai street names indicated will also prove useful as most street names are written in Thai script.
