Mount Emma and Old Mount Emma Trail

This trail is known for its challenging and varied terrain. You'll encounter steep ascents, particularly the initial climb to Mount Emma which can be a 'straight chute' with soft, powdery dirt. The ridge connecting the two peaks is a 'rollercoaster' with significant ups and downs. Expect loose scree and 'ball bearings on hardpacked loose' surfaces, especially on descents, which can make footing tricky and require careful navigation.

Given the trail's reputation for steep inclines, loose and slippery terrain, and significant elevation changes, it is generally not recommended for beginner hikers. It's best suited for those with prior hiking experience and good physical conditioning who are comfortable with challenging conditions.

The trail is accessible from Mount Emma Road. You can find parking available at a shallow saddle along the road, which serves as the trailhead.

Yes, dogs are generally allowed on trails within the San Gabriel Mountains National Monument. However, it's always best to keep them on a leash to ensure their safety and the safety of other hikers and wildlife.

The best times to hike this trail are typically during the spring and fall months. Summers can be very hot and exposed, while winters may bring snow or ice to the higher elevations, making the already challenging terrain even more difficult and potentially hazardous.

While there isn't typically an entrance fee for the San Gabriel Mountains National Monument itself, some parking areas within the monument, especially those managed by the Forest Service, may require a Forest Adventure Pass. It's advisable to check current regulations before you go.

The views from both Mount Emma and Old Mount Emma are truly rewarding. From Mount Emma, you'll see surrounding hills described as 'leopards' backs'. From Old Mount Emma, expect sweeping panoramic vistas of the San Gabriel Mountains to the south and the vast Antelope Valley to the north. On clear days, you might even spot Olancha Peak in the Sierras.

Absolutely. The initial climb to Mount Emma is very steep and can be loose. On descents, especially along the 'rollercoaster ridge' between the peaks, the loose scree can be like 'a bag of marbles'. Hikers often find a 'sideways shuffle-slide-push descent technique' helpful to maintain balance and avoid slipping. Good hiking boots with strong ankle support and trekking poles are highly recommended.

The Mount Emma and Old Mount Emma Trail is an out-and-back route. You will hike to both Mount Emma and Old Mount Emma and then return along the same path to the trailhead.

The peaks are named after Emma Pallett, whose family owned a ranch in the area. Interestingly, early maps mistakenly labeled a different summit as Mount Emma, which is now referred to as Old Mount Emma, while the true Mount Emma was later correctly identified.

Given the trail's difficulty and exposure, it's crucial to bring plenty of water, sturdy hiking boots with good grip, sun protection (hat, sunscreen), and layers of clothing. Trekking poles are highly recommended for stability on the steep and loose sections. A map and compass or GPS device are also advisable.
