The Pennypack Trail is a 2.4-mile rail-trail located mostly in Lorimer Park in Montgomery County and connected to Pennpack Park in Philadelphia County. Converted from the old Fox Chase-Newton Branch line, this trail runs from Rockledge Borough on the Philadelphia/Montgomery County boundary, north to Huntingdon Pike (Route 232) in Abington Township.
The Pennypack Trail now seemlessly connects to Pennypack Park and a 10-mile paved trail along Pennypack Creek, leading to the waterfront of the Delaware River. You'll realize the difference between rail-trail and park trail as you come upon rolling hills and curves. Celebrating their 100th anniversary in 2005, this is one of Philadelphia residents most beloved parks with access for cyclists as well as equestrians. There are several miles of unpaved trails open to mountain bikers and equestrians.
