Tips from the Community
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 few working water spigots on Diablo. Always tastes cold and fresh.

One of the fiercest peaks in the Bay. Always worth the effort. Itβs 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. Donβt bank on it.
