Took me a while to find the trailhead, which is in San Dieguito River Park, on the opposite side of the freeway. The trail begins on a bike path which crosses under the freeway and parallels Lake Hodges. In under 2 miles, the trail reaches the Bernardo Mountain Summit Trail. This trail meanders around the other side of the mountain before climbing to the summit. Great views from the top, while wiping the sweat away from my eyes!
