Ridley Creek

Ridley Creek is a tributary of the Delaware River in southeast Pennsylvania in the United States. The entire drainage basin is in the suburban Philadelphia area, but the upper creek and extensive park lands on the creek retain a rural character, while the mouth of the creek has long been heavily industrialized. It was named for the parish of Ridley, Cheshire, England. Two branches of the creek rise between Malvern and Frazer in Chester County, and then join about a mile south in Frazer. The creek flows south, then southeast to enter Delaware County and Ridley Creek State Park. Leaving the park, it passes the Tyler Arboretum and the town of Media, while entering a deep gorge. It passes local parks in Rose Vallley and the Taylor Memorial...
