“A long loop run through Mt. Diablo Foothills and to the summit of Mt. Diablo.”— Ryan Fanning
You take Wall Point Road to the Summit Trail. The Summit Trail will briefly become Green Ranch Road, and then rejoin Summit Trail. The entire Summit Trail is a moderate uphill with some steep sections. There are very few flat sections or descents, with the exception of parts of the rolling foothills, primarily on Wall Point Road prior to the Summit Trail.
Once you reach the summit, turn back down the Summit Trail, across the upper parking lot to the South Juniper Trail. Proceed down Juniper to Deer Flat Fire Road. Then, take Burma Road to Angel Kerley Rd to Little Pine Creek Trail to Stage Road Trail. From Stage Road Trail, turn down the BBQ Terrace Road back to Wall Point Road, which you can follow back to the parking lot. There are some seriously steep downhill portions here. Many of the downhill sections have loose gravel/rocks, so careful footing is required.
