Valley Green to Chestnut Hill Railroad Grade
Abandoned railroad climbs Wissahickon Gorge
This forgotten railroad grade served coal trains from the Pennsylvania Railroad’s main line up to the textile mills of Chestnut Hill from 1884 to 1958. The route begins at Valley Green Inn and climbs steadily through the Wissahickon Gorge on the original stone ballast, crossing three stone arch bridges that still bear the weight of modern vehicles. The steepest section near Cresheim Creek requires low-range gearing as loose ballast stones and washouts from decades of abandonment create significant traction challenges.
Moderate difficulty requires 4WD with low-range transfer case and skid plates for protection against sharp ballast stones. The railroad ties were removed in the 1960s, but steel rails remain embedded in some sections, creating potential tire hazards. Best attempted in dry conditions from May through October when creek crossings are manageable. No official vehicle access exists—this is technically trespassing on city parkland, though enforcement is minimal. The payoff is accessing some of Philadelphia’s most remote urban wilderness and spectacular views of the Wissahickon Creek valley that few people ever see.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner run this trail without modifications?
A stock 4WD with low range and decent ground clearance can handle it, but rocky ballast surface and uneven bridge foundations will punish low-hanging skid plates. All-terrain tires are strongly advised — street tires will struggle on wet rock.
Is the trail accessible year-round or does it close in winter?
Best season is May through October. Winter ice on the rock ballast and bridge foundations makes this trail genuinely dangerous, and Philadelphia Parks & Recreation may restrict access after significant snowfall or storm damage.
Do I need a permit to run this trail, and is there a fee?
No permit or fee is currently required for trail access. Philadelphia Parks & Recreation manages the corridor — follow posted rules, pack out all trash, and check their site for any temporary closures before you go.
What's the hardest section and what should I actually expect there?
The old railroad ballast is loose, jagged, and uneven throughout — there's no single crux, but the bridge foundation crossings demand careful tire placement at low speed. Water crossings can deepen after rain, so check conditions beforehand; what looks shallow can hide loose rock underneath.
Is there any dispersed camping along the trail or nearby, and how's cell service if something goes wrong?
No dispersed camping — this runs through Wissahickon Gorge inside Philadelphia city limits, so overnight camping is not permitted. Cell service is spotty in the gorge, so download offline maps and don't count on a signal to bail you out.
