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!
