San Andreas Lake is a hidden gem tucked into the hills of San Mateo County, just south of San Francisco. Originally a natural sag pond formed by the San Andreas Fault, it was transformed into a reservoir in the late 1800s and now serves as a vital water source for the region. The lake is off-limits for swimming or boating, but you can enjoy its peaceful beauty from the San Andreas Trail or the popular Sawyer Camp Trail, which runs along its eastern edge. It's a serene spot where you can walk or bike with sweeping views of the water and surrounding hills, all while standing right on one of the world’s most famous fault lines. Despite its proximity to urban life, San Andreas Lake offers a quiet, scenic escape steeped in natural and historical significance.

This 2,400-acre park stands as an oasis of open space, right on the fringes of San Francisco. The highest point of the ridge is just over 1,300 feet (almost 400 meters) in elevation, and the views are great!

This used to be a small, natural pond, but was expanded with the help of an earthwork dam that miraculously survived a famous earthquake in 1906 that more or less took place right underneath the dam. Because this is a reservoir you can't swim in it, but there's a great multi-use trail that you can follow as far as the Crystal Springs Dam.
