Mount Diablo State Park has an incredibly dense network of connecting trails, probably also plenty of rewarding summits, Eagle Peak is definitely one of them. The ascent is often steep (> 15%) occasionally a bit slippery but always well marked and generally easy to walk. The view "at the summit" (a small name post defines the summit) is great - from the SF-Bay to Mt. Diablo... and don't forget: look up into the sky to spot all the birds of prey (including eagles)... it's worth it!

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.

Nice views and toilets after reaching the summit.

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 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.

Can’t miss this one! At the very top of north peak, climb the metal ramp (take care) and head to the top.
