The 20-mile Perkiomen Trail follows the route of the Perkiomen Creek from Oaks to Green Lane Borough. It connects to the Schuylkill River Trail and the Audubon Loop. For most of its length, the "Perky," as it is known by many, uses the former rail bed of the Perkiomen Line of the Reading Railroad. This trail connects many public parks and historic sites, among them Lower Perkiomen Valley Park, Central Perkiomen Valley Park, Green Lane Park, John James Audubon Center at Mill Grove, Pennypacker Mills, and the local Skippack Township trail that continues to Evansburg State Park. The trail passes through the historic villages and towns of Arcola, Collegeville, Schwenksville, Spring Mount, and Green Lane, offering many town services for trail visitors.
