NorCal Challenge Overview > 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. 😉

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.
