The trail typically starts from the Pacific Crest Trail Trailhead – San Francisquito Canyon Road. Parking is usually available near this trailhead along San Francisquito Canyon Road.
The provided information does not explicitly state whether dogs are allowed on this specific loop. However, many trails within the Angeles National Forest permit dogs on leash. It's always best to check current regulations with the Angeles National Forest before heading out with your pet.
Spring is often ideal, especially for experiencing potential 'amazing super blooms' of wildflowers. However, the trail can be hiked year-round. Be prepared for exposed sections and bring extra water and sun protection, particularly during warmer months.
This trail is located within the Angeles National Forest. While there isn't typically an entrance fee for hiking, a Forest Adventure Pass may be required for parking at some trailheads within the forest. It's advisable to check the latest requirements before your visit.
While a section of the PCT leading to Grass Mountain is sometimes classified as moderate, the overall loop is generally considered a challenging or difficult hike due to its elevation gain and varied terrain. It's not typically recommended for absolute beginners.
You'll be treated to stunning panoramic views from the bald summit of Grass Mountain. These include vistas of the Antelope Valley, the Mojave Desert, and even Edwards Air Force Base on clear days. You'll also see Elizabeth Lake, Jupiter Mountain, Green Valley, and Burnt Mountain, along with an Angeles Forest crest view and the San Francisquito Canyon Overlook.
The trail starts as a single-track path that gradually ascends, eventually merging with a fire road. The ascent involves gradual climbing, and a 'meadowy ridgeline' with a dirt trail leads to the summit. Be aware of exposed sections due to previous fires, and some parts might be narrow with steep drop-offs.
Key landmarks include the summit of Grass Mountain, the Top of San Francisquito Watershed, and the PCT junction with Joey Rd and Forest Rte 7N01. Notable viewpoints offer sights of the Antelope Valley, Elizabeth Lake, and the Elisabeth Valley View from Grass Mountain ridge.
Yes, a significant portion of this route follows the iconic Pacific Crest Trail (PCT), specifically the PCT - California Section E and the Pacific Crest National Scenic Trail #2000. It also utilizes sections of the Firebreak, Forest Route 7N01, and South Portal Road.
Given the exposed sections and potential for warm weather, it's crucial to bring plenty of water and sun protection (hat, sunscreen). Sturdy hiking shoes are recommended for the varied terrain, and layers of clothing are always a good idea for changing conditions.
The section of the Pacific Crest Trail (PCT) on this loop is generally peaceful, as bikes are not allowed, ensuring a tranquil hiking experience. While the PCT is well-marked, pay close attention at fire road crossings to ensure you continue on the correct path.
