On the way back from Mount Sizer

2022 Mount SizerMount 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. 😉

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.
