This loop is very enjoyable in the spring, when the flowers come out. The trails in the eastern end of the park have a more isolated feel than those accessible by the Rim Crest and Carbon Canyon entrances, as the walls of the canyons block out most of the sights and sounds of civilization (except the 91 freeway).
From the campground, pick up the Lower Aliso Canyon Trail and head through a peaceful meadow, half a mile to a split. Take a right on the Skully Ridge Trail (the left road is the continuation of Aliso Canyon Trail, your return route). You pass by the turnoff for the Water Canyon trail, which is popular but often subject to closure due to adverse conditions.
Then you begin a steady climb to a ridge, where you get nice views of the western portion of the park, the Santa Anas in front of you and the eastern San Gabriel summits. At 2.7 miles from the start, look for the Brush Canyon trail branching off to the left. This trail, quite overgrown in some places, switchbacks down the hill to rejoin the Lower Aliso Canyon trail. Take a left and head north for two miles to return to the junction. A footbridge that crosses the canyon makes a particularly nice place for a snack break.
