The Conestoga Trail System is a 65.8-mile (105.9 km) linear hiking trail in Lancaster County, Pennsylvania. The system connects several relatively short and discontinuous footpaths with walks on paved roads. About 53% of the network's distance is made up of road walking, and those segments are intended to showcase the rural scenery of Lancaster County, utilizing three covered bridges and passing numerous Amish and Mennonite farms, as well as some urban and suburban neighborhoods in and around Lancaster. The footpath segments offer wilderness scenery of the type that can be found in many of Pennsylvania's forested areas, plus some walks alongside farm fields.Most of the off-road portions of the route are on private property, so except for several miles near the south end of the route, camping is prohibited along most of the Conestoga Trail System. The trail route is maintained by Lancaster Hiking Club, which regularly searches for options to relocate the route off of roads and into private or public woods and fields, so the route and distance of the Conestoga Trail System are known to change periodically.

The Norman Wood Bridge carries Pennsylvania Route 372 across the Susquehanna River between York County, Pennsylvania and Lancaster County, Pennsylvania.
