The system of public transport in Prague and in the whole Czech republic is very good. For traveling between the cities you can use buses or trains. Travelling to some destination is much faster by bus than by train. The right connection you can find for example at http://www.idos.cz. This site is available also in English language and you can find there all the connections with prices.
Travelling by public transport through Prague is also very easy. There are three types of transport: buses, trams and metro (subway). Prague metro has 3 lines – A (green), B (yellow), C (red) and is operating daily from 5 a.m. till midnight. Trams and buses are running non stop, only during the night (from midnight till 5 a.m.) are operated as special night lines under different numbers.
For all kinds of transport you can use one ticket. By entering the bus, tram or metro station you need to mark the ticket in the yellow machine. It prints time and date on your ticket. From this moment is the ticked valid for various periods, depending on the type of the ticket.
