The approach from the south is the most popular route to the Cowles Mountain, the highest point in the city limits of San Diego at 1,591 feet, but hikers looking for more of a challenge can begin at Big Rock Park in Santee. This route also has less traffic than the south trail, at least during the first part of the hike before the trail joins a major service road.
Start by following the Big Rock Trail, passing through a meadow alongside a housing tract. The antenna-dotted summit of Cowles stands unmistakably in the distance. You cross a seasonal stream and stay right as two unofficial trails branch off to the left. Soon you’re ascending through chaparral, gaining better and better views of the surrounding suburbs as you climb. You pass a junction with a spur coming up from the residential neighborhood and reach another split about a mile from the start. This is the Mesa Trail, an option for a different return.
Past this intersection, the trail continues to ascend through the brush, reaching a dirt service road at 1.5 miles. Turn right and follow it toward the summit, at first enjoying a flat stretch with great views to the south. Soon you’re climbing, passing another trail coming up from Barker Way. A steep ascent brings you to the summit, where you can enjoy a 360-degree panorama including the ocean to the west and El Capitan and the Cuyamaca range to the east. If visibility is good, you may see Orange County’s Santa Ana Mountains to the northwest.
If you decide to use the Mesa Trail as an alternate descent, you can follow it for 3/4 of a mile from the junction with the Big Rock Trail to its bottom end at the Mesa Service Road. This right-of-way is a proposed extension of Mesa Road which would connect with Lake Murray Blvd. to the south. Turn left and follow it north for half a mile back to your starting point. If there have been recent rains, look for a small seasonal waterfall on the left side of the road.
