Full Sail is the latest addition to the Reserve's trails. Built in 2016, it links Hillside Park on the west side of the Reserve, with the numerous trails originating from the Harrison Hollow and Ussery trailheads. It provides an easy, meandering experience that looks out just above the north end treetops.
Harrison Hollow is a mecca for dogs. It is a gentle stroll up the drainage where you can expect to encounter man friendly regulars with their pets. This trail contains a sand and gravel surface, allowing it to be useable when most other trails are not due to muddy conditions. Short loops can be made by returning via either Harrison Ridge #58 or Who Now Loop #51.
These trails are native surfaced and as such should not be used when conditions are muddy.
