On the AllTrails.com website, reviewers give the Leiper-Smedley Trail in Wallingford 4.5 stars and designate sit as easy. The Leiper-Smedley Trail is a 4.8 mile moderately trafficked out-and-back trail that is good for all skill levels. The trail is primarily used for hiking, walking, trail running, and nature trips and is best used from March until December. Dogs are also able to use this trail but must be kept on a leash. Parts are paved (south of Baltimore Pike) and going north on the Pike are single tracks worth checking out. It’s location near the Blue Rt. makes it noisy, but a chance to see the historic Leiper House and Smedley Park make it interesting. An issue worth noting is that it crosses Baltimore Pike at a red-light intersection. You can also access the other side of Crum Creek by taking Wallingford Road for a good forest trail.The Thomas Leiper Estate, also known as Avondale, is a historic estate that was built by Thomas Leiper around 1785, and named Strath Haven after Leiper's birthplace in Strathaven, Scotland. The estate includes a three-story, yellow stuccoed mansion house, “Fireproof” vault, communal outhouse, barn, carriage house, smokehouse, warehouse, tenant's house, and a quarry. It was added to the National Register of Historic Places in 1971. The Friends of the Leiper House offers weekend guided tours of the house from April through December.
Smedley Park was named after Samuel L. Smedley, the founder of Delaware County's Parks & Recreation Board. Conveniently located on 120 acres of land between Media and Springfield, Smedley Park has been transformed in recent years into a multi-purpose recreational area while still maintaining all of its natural beauty. The grounds feature shaded picnic groves, safety-conscious play areas for children, hiking paths, walking bridges over Crum Creek, and playing fields for baseball, softball, soccer, and lacrosse. Nestled among the trees are the Environmental Center and the Lewis House, headquarters of Penn State's Cooperative Extension of Delaware County. The extension operates numerous programs, including the 4-H Club, Master Gardeners, and a variety of educational opportunities in agriculture, horticulture, nutrition and more.
