PENNSYLVANIA - Accessible Nature

Pennsylvania has a lot of trails with minimal obstacles. Some are very easy and others are wheelchair accessible. Here are just a few of them.
These links were found through Internet search. I would love to have some first-hand recommendations. With your help, we can share our knowledge with disabled people everywhere and also increase awareness of the need for more accessibility. Please e-mail me with your suggestions using the form in the sidebar.

Thank you to David Robertson for the following information:
“The Pennypack Parkway (between Mason’s Mill Road and Pennypack Road) is very accessible for disabled visitors. It was an old, flat, level road that is now abandoned and surfaced with crushed stone grit. It may have a few minor erosion rills in places, but I recommend it to people in wheelchairs and families with children in strollers.”
“Montgomery County’s new Pennypack Trail, a rails-to-trails project created on the bed of the old Fox Chase-Newtown regional rail line, parallels the Creek Road Trail on the east side of the creek. That trail is flat, even, and level–perfect for disabled users. It is heavily used. The Pennypack Trust does not maintain that trail; it is the responsibility of Montgomery County, and it extends southward to the county’s Lorimer Park for a total length of just over 5 miles.”
?? “The Creek Road Trail, also an old abandoned road, is subject to flooding because it is located so close to the creek. While the trail is mostly flat and level, the surface is very, very uneven. In places, it is gravel, in other places it is paved, and in still other places it has washed out down to the ballast under the asphalt. I wouldn’t recommend it for a disabled person.”

Delaware & LeHigh National Heritage Corridor
From Wikipedia: “The D&L Trail is a 165-mile (266 km) multi-use trail. The trail incorporates rail trails, rails with trails, share-the-road sections, and canal towpaths…The trail follows the route that anthracite coal took from mine to market. It winds through northern mountains and along the banks of the Lehigh and Delaware Rivers through northeast Pennsylvania, the Lehigh Valley, and Bucks County. The D&L Trail passes through towns, industrial powerhouses, and along remnants of the Lehigh and Delaware canals. This earthen path exposes walkers, hikers, bicyclists, and others to Pennsylvania wildflowers, waterfalls, and wildlife.” The corridor crosses may state, county and local parks.
