Three handicapped parking spaces are available in our Corry Street Parking Lot. The Trailside Museum is accessible by accessing the wood ramp, located at the center of the parking lot. The Vernet Ecological Center is accessible by following the paved walkway, leading off of the left, rear corner of the parking lot. Due to covenant protections, parking is no longer available in the former Yellow Spring parking lot. This has resulted in a loss of handicap access to the Yellow Spring. We are working toward an alternative access plan.

Hiking Trails

All visitors must remain on designated trails. Failure to stay on trails disrupts the delicate ecology of the Glen and can harm the flora and fauna of the preserve. Stay on the trail even if it is muddy or wet. Walking around the mud widens the trail, damaging growth on the forest floor and resulting in a muddier trail in the future. Mud is part of the outdoor experience! Please, hike through it.

Though we make every effort to protect this land and the natural springs and waterways within our 1000 acres, please remember that we are surrounded by commercial farms and private properties that may not utilize environmentally friendly practices. Creeks, rivers, and groundwater contain contaminants from these offsite locations. Consumption and/or contact with waters within the Glen may pose a risk to your health.
