Buses come in from the surrounding suburbs to the center of Uppsala and arrive at the Central Station, where the trains also arrive. Once you arrive in the center of Uppsala, all the major attractions are within easy walking distance. However, if you're going to explore Gamla Uppsala, you need to take bus no. 2 or 54, departing from the Central Station.
To get your bearings, it helps to know that the small Frysiån River runs through the town, and the main square, Stora Torget, leads to a pedestrian shopping district.
