Tram lines snake through many of the main streets in Budapest, but they aren’t as extensive as the bus routes. In the heart of the city, the trams are often jam-packed, but they are quick. Remember to punch your ticket in one of the validators located near the doors, if you can muscle through the crowd.Buses are the best bet for reaching the more out-of-the-way places in Budapest. Though they run frequently, they often are crowded. Taxi cabs are great if you want to get where you’re going fast. Taxi drivers, on the other hand, can cause you a lot of grief if you’re not careful.
