Trek Highlights

The Pacific Crest Highway rises above the Angeles Forest Highway and below some buzzing power lines. The ground is covered by chaparral, toyon, and manzanita. Even at the start of the hike, it is warm, yet nice and cool at the v-shaped drainages.

This is a decidedly Laker friendly path with purple and gold flowers. The air is fragrant and smells like a cup of tea. Chipmunks and lizards scurry away. A young buck darts up the hill from out of the bushes.

Leopard spot hills flatten out to the north in Antelope Valley. There are some shady parts on the western flank before noon. At narrow sections, watch out for prickly holly leaves, spiky yucca, and beautiful toxic poodle dog bushes.

After some mild switchbacks, the trail reaches Pacifico’s ridge, which looks like an inviting sandy carpet has been unfurled for you. At the 6-way junction, you can take a short and steep route or a more gradual path that swings around the summit. Pacifico Mountain Summit Road, aka pine cone alley, is a wide trail straight to the top. After a final bend, there is a beautiful campground with a flat summit block and plenty of trees and shade. There is a collection of giant boulders at the summit, where you can practice bouldering. From a looping path, you can see the Antelope Valley as well as the front range of the San Gabriels.
