San Andreas Lake

Highlight • Lake

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.

Pulgas Water Temple

Highlight • Monument

San Francisco built Pulgas Water Temple as a monument to the engineering marvel that brought Hetch Hetchy water more than 160 miles across California from Yosemite National Park in the Sierra Nevada Mountains to the Bay Area. The Hetch Hetchy Project took 24 years to build through the Great Depression at a cost of $102 million.
On October 28, 1934, the roar of Hetch Hetchy mountain water greeted everyone gathered at Pulgas Water Temple to celebrate its arrival. With vivid memories of the fire that had raged after the Great Earthquake of 1906, the city rejoiced in its new secure, plentiful supply of high quality drinking water. The frieze above the columns expresses the city’s relief: “I give waters in the wilderness and rivers in the desert, to give drink to my people.”
Pulgas Water Temple was designed in the Beaux Arts style by William Merchant, a San Francisco architect trained by Bernard Maybeck. Merchant’s design featured fluted columns and Corinthian capitals to reflect the architecture of ancient Greeks and Romans, whose engineering methods were used to build the new water system. Artist and master stone carver Albert Bernasconi brought Merchant’s drawings to life.
Pulgas Water Temple is located about one-half mile south of the Cañada Road trailhead.
Open free to bikers & pedestrians every day, car parking opens only M-F 9-4

Tafoni Sandstone Formation

Highlight • Natural Monument

The Tafoni sandstone consists of sand from ancient dunes cemented by water-soluble calcite. Due to calcite, water easily passes through the porous rock, thereby dissolving the calcite and then depositing it as crystals on the surface when it evaporates. Hence the strange shapes of this rock.

You're not hallucinating: This monument was deliberately built in the style of ancient Greek and Roman architecture, to commemorate the Great Depression-era Hetchy Hetchy Project that brought water down from the mountains to the Bay Area. The frieze says, “I give waters in the wilderness and rivers in the desert, to give drink to my people.”
