Mount Diablo, is the Bay Area second-highest peak at 1173m (3849ft). The challenging climb features constantly fluctuating gradients averaging 8%, with tough sections up to 18% and a brutal 23% finish in the last 200m. The equally demanding descent requires good bike handling due to tight corners, potholes, and strong winds. The road to the top is open daily from 8 AM till sunset.

For the Rocky Ridge trail hike, I suggest to have a hat, hiking poles, sun-glasses and of course water. Most of the trail is without any shade. Depends on the season, some portions of the trail could be muddy. Park the car in the parking lot at the end of Bollinger Canyon Road. If parking lot is full you can park along the road. This is the staging area and the start and end of our hike is here. Restrooms are available only at this place. To start the Rocky Ridge Trail, go to the north-west corner of the parking lot (north of the restrooms) and start going up on the paved road. Note that most of the climb is this segment, but afterwards the trail is pretty easy. No shade on Rocky Ridge, some shade on Elderberry.
