This map covers the following areas: Main Prague Map 1:10,000 Prague Metro MapGreat for 'streetwalking' There are maps with even more detail, but this map is an essential. Lightweight, laminated (waterproof), pocket-sized, and with almost all the detail that most visitors need. Fully-opened, it is still small, unobtrusive, and easy to use. A handy gazeteer lists many streets and monuments, with map grid locations. There are some very tiny streets/alleys that are hard to make out, but that is true for almost any pocket-sized folding map. I buy a Streetwise for any city destination.
