As you will see, this is a work in progress, but the site format has been established, so there may be changes, but hopefully that'll just mean more information. Featured hikes will range geographically from around Robert Louis Stevenson State Park to the north, to Mount Diablo in the east bay, Henry Cowell State Park to the southwest, and Henry Coe State Park to the southeast. The centerpiece of this site is the hikes. Each hike has its own page.
Some locations have multiple featured hikes.
Information about other hiking options from each location are included within each featured hike's page. Most hikes take place on trails, rather than wholly on paved paths. Paved paths are great for cycling, and popular for joggers, and family outings. In my mind, they aren't the optimal locations for a hiking experience. Besides, a long walk on pavement hurts my knees.
