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.

There are a bunch of great hiking and biking trails around the reservoir. Some, like the Shore Trail, are two-lane paved cycleways with no vehicle traffic, and others are unpaved dirt roads up in the hills. All are beautiful trails to explore on two wheels!
