Trail guide
Gilley Trail is a wooded point-to-point path from Gilley Field to the Great Notch junction. The main line is about 0.6 mile one way and takes roughly 20–30 minutes. It climbs toward Great Notch. This is not a loop: turn around at the junction for about 1.2 miles round trip, or continue onto adjoining trails.
Elevation models put Great Notch about 50–70 m (165–230 ft) above Gilley Field. A park trail catalog lists 0.7 miles (1.1 km), but does not explain whether it includes nearby Gilley-named connectors. This route follows the main line between Gilley Field and Great Notch.
A historic inventory says the path appeared on a 1915 guide and was probably built around 1911. It also records two cedar stringer bridges with redwood decks; their current condition was not verified.
Start at Gilley Field Parking Area. Dogs are allowed on this route and must stay on a leash no longer than six feet.
