From the west entrance, parking is available at a lot on the corner of N Windsor Avenue and Ventura Street. From the lot, follow the trail north for a mile and a half, staying left at the fork with Fern Truck Trail
and El Prieto. Continue climbing for another three miles until the trail is closed past Paul Little day use area.
From the east entrance, park at the Chantry Flat Rd. parking lot. Be aware this lot can fill up on weekends, but additional parking can be found a quarter-mile back down the road. From the lot, take the Santa Anita Canyon Ave (Forest Rte 2N40) north to the counter-clockwise start of the Gabrielino Trail (NRT). Given the current closures, riding the trail from this east entrance will cover roughly 18 of the 27 total miles. At the start, the trail climbs abruptly to Sturtevant Falls, continues north toward the Spruce Grove Campground, and culminates at Newcomb Pass beyond that. This section is still recovering from fires and has many stream crossings. From Newcomb Pass, enjoy the first thousand-foot descent to Devore Campground when a gradual climb begins again. This nearly 7-mile climb approaches Red Box Gap between San Gabriel Peak and Mt. Lawlor. A number of different trails can be accessed from this point.
Continuing west until the closure at the Comodore Campground, the trail descends for roughly five miles on fun, technical singletrack.
