I came to Harrisburg to see the Pennsylvania State Capitol, but while I am here, I spent some time exploring. Harrisburg is one of those old cities where downtown is a mix of historic and modern buildings. Some of the historic buildings have been preserved; some need some preservation. It is a mostly walkable city though. There is a nice riverwalk, at least part of it is close to the water level next to the levee, and another parallel part of it is on top the levee.
One place that I really enjoyed walking to is City Island, which can be accessed on foot by the Walnut Street Bridge, a pedestrian and bicycle only bridge, that connects downtown to the island in the Susquehanna River. From City Island, I took a ride on the Pride of the Susquehanna riverboat that takes a short cruise up the river. By the time the river gets to Harrisburg, it is about a mile wide, but it averages only about 3.5 feet deep. On the cruise, I saw some people standing in the middle of the river, which only went to their waist, next to their pontoon boat.
