Developed from a master plan in March 2003, the Northwest Lancaster County River Trail is a multi-purpose, public recreation trail approximately fourteen miles long, spanning five municipalities at the northwestern edge of Lancaster County. Parts of the trail are also owned by Lancaster County and the Lancaster County Solid Waste Management Authority.
The trail follows the route of the historic Pennsylvania Mainline Canal and uses some of the original towpath that remains along the corridor. This provides ample opportunities to interpret the numerous industrial archaeological remains such as abandoned canal locks; the iron furnaces at Chickies Rock; and the old quarry operation at Billmeyer. The trail also connects the historic river towns and villages of Columbia, Marietta, Bainbridge, and Falmouth.
