Hermesprota Creek begins in the Har Zion Cemetery near the community of Collingdale, Pennsylvania. It flows south-southeast for several tenths of a mile before passing under U.S. Route 13 and turns west and enters Sharon Hill, Pennsylvania. The creek turns south and enters the communities of Darby Township and Folcroft. Hermesprota Creek then enters the John Heinz National Wildlife Refuge and receives two small unnamed tributaries, from the right and left banks respectively. After several hundred feet, it reaches its confluence with Darby Creek.[1]
Hermesprota Creek joins Darby Creek 3.55 miles (5.71 km) upriver of its mouth.[2]
