Bay Area Challenge Overview > The Peaks > Mount Sizer
Mount Sizer may be little more than a highpoint on the Blue Ridge, but getting there is what makes this hike a challenge. You'll gain over 3,600 vertical feet in 15 miles, including a climb on one of the steepest trails in the Bay Area, affectionately called “The Shortcut.” Your legs will probably think of a better name for it. 😉

Henry Coe State Park is the largest in the California State Park system.

Hiking Mount Sizer
This loop hike gives you a grand tour that begins and ends at the park headquarters. There are several campgrounds along the route, so backpacking this loop is a viable option if you want to break it up over a couple of days. You'll climb and descend several times, which accounts for the over 3,600 feet of vertical you'll experience.
