Location
McPherson Peak is named after rancher H. M. McPherson who lived here at what is now Aliso County Park and had a hog pen after which one of the trails is named.
Routes 1 and 2 start at the park, which has a nice campground, picnic area and restrooms. Route 1 is a scenic and enjoyable route that crosses Aliso creek to gain a ridge that ascends across various bumps to the peak with its radio towers. Route 2 also crosses the creek, but then follows along the creek on the Hogpen Trail for a cool and beautiful hike to join the road for a 1.5 mile road walk to the summit. Route 3 is drive-up or near drive-up after a long but scenic drive up tree-lined Sierra Madre Ridge Road. McPherson is usually climbed in conjunction with nearby Peak Mountain; this is often done as one long driving day for both peaks, but misses the beautiful hike from routes 1 and 2. Hiking Peak from McPherson and back (Peak Mountain Route 2) adds 6.5 miles and 1000′ gain.
