Virtually everything in the historic city center is within easy and leisurely walking distance. Sites across the river require a little more walking but still not too much. The terrain is flat and biking is very popular among the locals. Taxis are easily available at the train station and across the street from the Governor's Palace in the center of town. There are rental cars at the small airport just outside town. Parking can be a challenge downtown, however there are several parking garages outside the city center, the largest is behind Teatro Due. The city has an access control system which limits entrance to the city center to local tagged vehicles only. This system is generally switched off after midnight. There is an extensive local bus line.
