The Schuykill River trail is a multi-use trail that is planned to run some 130 miles when completed. Today, 60 miles are accessible, and there are continued developments and improvements. The section accessible from central Philadelphia is about 10.5 miles, starting at South St. and continuing past Manayunk. The most developed section is to East Falls, which is 4 miles from the Museum of Art. You can do a there and back or cross over to the west side on one of the bridges and do a loop back. There are many options to extend the run north, and then slightly south to near the Univ. of Pennsylvania. Recently, a 2,000 foot long boardwalk, running parallel to the eastern shore of the river from Locust Street to the new stair tower on the south side of the South Street Bridge was completed, providing an easier connection for people with bicycles. This project provides an important link to the Schuylkill River Trail and Center City from University City and West Philadelphia.
For a less populated, off-the-beaten-track option, use the Manayunk Towpath which parallels the canal and the Schuylkill River. It can be accessed from the Schuylkill River Trail to the west, or Fairmount Park to the east, and features a combination of boardwalk, gravel, and dirt running.
