PCT junction with Joey Rd and Forest Rte 7N01

The Grass Mountain Loop via PCT and Firebreak offers a diverse and rewarding hiking experience in the Angeles National Forest. You'll traverse varied terrain, from singletrack through small pine groves to open ridgelines near the summit of Grass Mountain, where the vegetation shifts to manzanita and chamise. The route provides panoramic views of Green Valley, Jupiter Mountain, and the Antelope Valley, making the 9.7-mile (15.6 km) journey feel like a true adventure.

Planning your visit is straightforward, with the trailhead located off San Francisquito Canyon Road, offering convenient parking. This moderate hike involves a significant 1799 feet (548 metres) of elevation gain, so be sure to bring plenty of water, especially during warmer months. The estimated duration is around 4 hours and 47 minutes, making it a solid half-day outing, and dogs are permitted on leash.

One of the most notable aspects of this trail is its integration with the Pacific Crest Trail, allowing you to experience a segment of this famous long-distance route. The loop also incorporates fire roads and utility roads, providing different perspectives and challenges. It's a favorite for local perspectives of the Antelope Valley and offers a good workout for those seeking a challenging hike with expansive views.
