Tips from the Community

This is a challenging summit that is well worth the views. If you are looking for a secluded peak in the heart of the San Gabriels with panoramic views, you are in for a treat. Much of the trail to get here is shaded, and there are places where you can let dogs run off-leash. The scramble to the summit is steep and has loose gravel, so hiking poles may be helpful.

Frequently Asked Questions

Are dogs allowed on the trails in the San Gabriel Wilderness?

Yes, dogs are generally permitted on trails within the Angeles National Forest, which includes the San Gabriel Wilderness, but they must be kept on a leash. Always carry enough water for your pet, especially on hot days, as the terrain can be exposed and demanding.

What are some good family-friendly hikes in the area?

While many trails in the San Gabriel Wilderness are rugged, the surrounding Angeles National Forest offers easier options suitable for families. A popular choice is the trail to Sturtevant Falls, a relatively moderate hike leading to a beautiful 50-foot waterfall. Another great option is the Eaton Canyon Natural Area, which features a mostly flat trail to the 40-foot Eaton Falls.

Are there any hikes that lead to a waterfall?

Yes, the San Gabriel Mountains are known for several waterfall hikes. Besides the family-friendly trails to Sturtevant and Eaton Falls, more experienced hikers might seek out trails like Trail Canyon Falls or Switzer Falls, which offer a more strenuous but rewarding experience.

Do I need a permit to hike in the San Gabriel Wilderness?

For day hiking in most parts of the San Gabriel Wilderness, you typically only need a National Forest Adventure Pass for parking at trailheads. However, a free Wilderness Permit is required for overnight stays (backpacking). Some specific areas, like the Bridge to Nowhere, are on private land and may require separate permits or fees from private operators. Always check with the Angeles National Forest for the most current regulations before you go.

When is the best time of year to hike in the San Gabriel Wilderness?

Spring and fall offer the most pleasant conditions, with milder temperatures and blooming wildflowers in the spring. Summer can be extremely hot, especially at lower elevations, so hikes should be started early in the morning. Winter can bring snow and ice to higher elevations, requiring specialized gear like microspikes or crampons for safety.

Is it possible to go backpacking or camp overnight?

Yes, backpacking is a popular activity. You will need a free Wilderness Permit for any overnight trips into the San Gabriel Wilderness. There are designated campgrounds available, such as the Little Jimmy Campground, which can be reached via several trails. Always practice Leave No Trace principles to protect the environment.

How can I check for current trail conditions or closures?

Before any hike, it is critical to check the official Angeles National Forest website for the latest alerts on trail closures, fire restrictions, and weather conditions. Trails can be closed due to storm damage, fires, or maintenance, so verifying their status is an essential part of planning your trip.

What is the landscape like in the San Gabriel Wilderness?

The terrain is extremely rugged and scenic. You'll find a dramatic mix of deep, steep-walled canyons, soaring peaks, and lush riverside areas. The vegetation changes with elevation, starting with dense chaparral on the lower slopes and transitioning to oak woodlands and forests of pine and fir at higher altitudes.

Are there any good loop hikes available?

Yes, there are several excellent loop hikes. For a very challenging day out, the Mount Williamson, Goodykinz Peak, and Pallet Mountain loop is a 15.1-mile (24.3 km) trek that connects multiple peaks. It's a strenuous route with significant elevation gain, best suited for experienced hikers.

What kind of wildlife might I see?

The San Gabriel Mountains are a hotspot of biodiversity. While hiking, you might spot mule deer, coyotes, and a wide variety of birds. More elusive animals like bighorn sheep, mountain lions, and black bears also inhabit the area, so it's important to be aware of your surroundings and know proper wildlife safety protocols.

What do other hikers enjoy about the San Gabriel Wilderness?

The area is highly rated by the komoot community. Reviewers often praise the stunning views from the peaks and ridgelines, the sense of true wilderness so close to Los Angeles, and the variety of trails that offer a challenge for every skill level. The descent into Devils Canyon is often mentioned for its rugged beauty.

How many hiking trails are in the San Gabriel Wilderness?

There are over 50 designated hiking trails to explore in and around the San Gabriel Wilderness. These range from short, moderate canyon walks to difficult, all-day ascents of major peaks, offering a wide variety of options for hikers.

Can I reach any peaks on a moderate hike?

Yes, you can. The hike to Mount Williamson is a great example of a moderate summit trek. It's a roughly 4.2-mile (6.8 km) out-and-back trail that provides fantastic views without the extreme difficulty of the region's highest peaks.
