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.

The Pacific Crest Trail to Grass Mountain offers a rewarding, difficult hike through the Angeles National Forest, leading to expansive views. You'll traverse a singletrack path, often exposed, winding through drainages and past "pretty grasses." From the summit of Grass Mountain, you'll be treated to panoramic vistas of the Antelope Valley, Jupiter Mountain, and the Green Valley, with the Mojave Desert stretching into the distance.

This 13.0-mile (20.9 km) route involves a significant 2229 feet (679 metres) of elevation gain, typically taking around 6 hours and 18 minutes. Due to the exposed nature of much of the trail, especially after the Station Fire, it's crucial to carry ample water, particularly during warmer seasons. While generally well-marked, be aware of a brief section where the PCT merges with a fire road before rejoining the singletrack.

This segment is part of the much larger Pacific Crest Trail, a continuous path from Mexico to Canada, offering a unique opportunity to experience a piece of this iconic long-distance route. The trail generally prohibits bikes, ensuring a more peaceful hiking experience. Keep an eye out for potential super blooms around Elizabeth Lake at certain times of the year, adding to the natural beauty.
