Access to trail can be made by programming 99 Maple Street Brookville, PA into your GPS. There is a small parking area there. A path takes you down to the trail.
Also, there is the Depot Street spur that is available for walking once you cross Redbank Creek to the west side. That trail will take you to Route 36 from which you would either turn back the way you came or walk down Route 36 to Race and then Maple Street.
