The Rocky Run Trail, located in large part on property owned by the Natural Lands Trust, is directly accessible from a parking lot adjacent to the Valley Road bridge over the Rocky Run with white trail markers. The downstream portion of the trail parallels Rocky Run, one of the most beautiful streams in Delaware County, revealing old-growth hardwoods, steep slopes, and magnificent rocky stream vistas. The trail itself is relatively easy walking and connects at its lower end to the Darlington Trail just before the Rocky Run reaches the Chester Creek. The upstream portion of the trail crosses open meadows below the Granite Farm Estates Retirement Community, wanders through woods on County property, passes the Fair Acres complex, and then connects over private property (the Lima Estates Retirement Community) to the Tyler Arboretum trail network. Use of other Arboretum trails or facilities is subject to their membership and fee policies. These trails interconnect with Ridley Creek State Parks trails (from middletowntownship.org).
