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.

I would have a look at the tide tables before planning a visit. There is a tidal pool where you can see fascinating marine life. Please don’t walk on any rocks anywhere here, it’s somebody’s home.

The Newton Drury Parkway closes to cars the 1st Sat of each month Oct-May. Very quite in the redwood forests as you cycle by (or coast if you're headed N to S).

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.
