Trail shared by Haiyan Jia

Don't be turned down by the steep hills at Las Trampas; this trail has gradual climbing and is very manageable.

Runner Notes

There are no water sources available, so bring your own water. Pit toilets are available about 500 feet past the gate to start the trail or at the staging area about a half mile from the dirt parking area.


To get to the trailhead, drive along the Bollinger Canyon Road westbound until the end (about 10 minutes driving from the Crow Canyon Road intersection). About a half mile after passing the gate, the staging area will be on the left where you can park your car and use the bathroom. (If you arrive outside of open-gate hours, you may find the park gate is closed, but don't panic. You can park at the left side of the unpaved parking area and head through a small gate to the right. After about 500 ft, make a left and go up the hill gradually.)

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.
