“Don't be turned down by the steep hills at Las Trampas; this trail has gradual climbing and is very manageable.”— Haiyan Jia
The trailhead is located on the left side of the picnic area, and the first mile is along the foothills of Rocky Ridge toward the east. At about 0.3 miles, you'll reach a horse camp. Follow the Elderberry Trail sign and turn right to start climbing. As you climb, look east for a pleasant canyon view.
After about 2 miles, you'll arrive at the junction of Elderberry Trail and the Rocky Ridge View Trail. Enjoy a quick rest on the chair donated by a runner's friend, while enjoying the panoramic view of Mt. Diablo, Tri-Valley, and San Mateo Bridge. You can continue to run toward the east along the ridgeline until you reach the park boundary, or you can just return the way you came down the hill all the way back to the parking lot. This can be an easy, relaxing 4-miler or 5-miler if you add the ridgeline extension to the boundary.
