This adventurous hike offers excellent views of the high desert and the north slope of the San Gabriel Mountains. With one major steep ascent and several smaller (and also steep) climbs in both directions, it’s quite a workout too. It’s also completely exposed, so plan accordingly. The destination of the hike is Old Mt. Emma (elevation 5,063), so named when it was discovered that the ridge had a taller summit southwest. That point (elevation 5,273) became today’s Mt. Emma. The peaks and ridge are named after Emma Pallett, daughter of a local rancher.
From the parking area, cross Mt. Emma Road and begin ascending the signed trail. Loose in spots but easy to follow, the trail passes by small cacti, yuccas and skeletal trees burned in the Station Fire and other wildfires as it ascends steeply up to a ridge (0.2 miles). Here it merges with a fire road and continues the stiff climb. Keep track of this spot on the return as it is not well marked. As you grind up the west side of Mt. Emma Ridge, logging one thousand feet of elevation gain in less than a mile, you are rewarded with increasingly panoramic vistas.
At 0.9 miles you reach the flat summit of Mt. Emma, where you can enjoy a 360-degree view, extending west to the Sierra Pelona range. If you’ve had enough at this point, you can return via the same route, but to continue to Old Mt. Emma, follow the clearly defined trail leading northeast along the ridge. Despite being lower than Mt. Emma, adding Old Mt. Emma doubles the total elevation gain of the hike, due to the ascents and descents along the ridge. The terrain is often loose and rocky; in some spots you may be able to get better traction in the dirt at the side of the trail.
The ridge drops sharply to a saddle (1.4 miles) and climbs to a bump (1.9 miles). Here, you get a good view of the juniper-dotted slope of Old Mt. Emma. One more steep descent and climb brings you to the peak. Just below, bear left on a use trail branching off from the ridge and climb to the top of Old Mt. Emma, marked by a rock cairn and a ragged flag. Relax and enjoy the views, including the distant Tehachapi Mountains and southern Sierras, while charging your batteries for the return. The steep ascents and descents on the way back should not be taken lightly.
