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.

Keep going to the top! When you get to the metal ladder/steps, climb them for the true summit! A bit of radiation, never hurt anyone, right?

North Peak offers the best viewpoint in the entire area. A tower at the top gives panoramic views of Mount Diablo State Park and the surrounding peaks. The trails in the park form a network that allows you to create different loops depending on how far you want to run, and you can link up this peak with some of the others during a longer session.

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 — there is a water spigot up there to fill up bottles. Also a store is open at some times. Don’t bank on it.
