Loop is the most popular hike at San Bruno. An easy under 3 mile circuit, the loop makes a fine exercise track for neighborhood
joggers and walkers. In Spring, Saddle Loop is a frequent destination
for wildflower enthusiasts. It's also a great "orientation"
hike for active out-of-town guests. Not only are there unparalleled views
of San Francisco, but on a clear day you may see the Farallon Islands,
much of the Point Reyes Peninsula, Mount Diablo, Mount Tamalpais, and
the Santa Cruz Mountains.
