Los Penasquitos Canyon Preserve is centrally located in San Diego and is easily accessible from the 805, 15 and 56 freeways. The focal point of the canyon is Penasquitos Creek, which runs the length of the preserve. A little over 3 miles west of the Black Mountain Road trailhead there is a quaint, quiet spot with a waterfall, perfect for a picnic lunch.
Trails are abundant on both sides of the creek and there are several creek crossings, including a couple of bridges. Hike as little or as much of the trail as you like. This suggested 6.4 mile route is just one of many possible longer or shorter routes you may choose to take along the creek.
