Prague's tram system provides fast, easy connections within the city and far into the suburbs. Take tram 22 or 23 from Malostranske namesti to Prague Castle, or transfer at Malostranska to a tram or Metro across the river to the Old Town area. Adult fares are as low as 24 crowns (about $1.20) for 30 minutes to 310 crowns ($15.50) for a three-day pass. Passes are good on the trams, Metro and buses. Riding it makes you wonder why so many cities tore out their tram tracks to make more room for cars.
