June 18, 2025, Mount Diablo Summit

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.

One of the fiercest peaks in the Bay. Always worth the effort. It’s often much cooler on the summit than the rest of the trails β€” there is a water spigot up there to fill up bottles. Also a store is open at some times. Don’t bank on it.
