Sawyer Camp Trail

Sawyer Camp Trail is a prominent multi-use recreational path located within the San Francisco Peninsula's San Mateo County. The trail traverses a scenic corridor along the western shoreline of the Crystal Springs Reservoir, a critical component of the San Francisco Public Utilities Commission's Hetch Hetchy water system. Managed as part of the San Francisco Water Department watershed lands, it offers a paved, accessible route for hiking, cycling, and jogging amidst a protected natural landscape, connecting the communities of Millbrae and San Mateo.

History

The trail's namesake originates from Levi Sawyer and Ciriaco "Crystal" Camp, who operated a popular 19th century roadhouse and toll road in the area, serving travelers between San Francisco and San Jose. This historic route was later incorporated into the right-of-way for the Spring Valley Water Company, a private utility that developed the Crystal Springs Reservoir system. Following the 1906 San Francisco earthquake, the city of San Francisco acquired these lands and water rights, which are now administered by the San Francisco Public Utilities Commission. The modern recreational trail was officially established and paved in the 1970s, opening the protected watershed to public non-motorized use while ensuring the security of the regional water supply.

Description and route

The trail is a six-mile, uniformly paved linear path that runs north-south parallel to Skyline Boulevard (State Route 35). Its northern terminus is at the intersection of Skyline Boulevard and Hillcrest Boulevard near Millbrae, while its southern end is at the Crystal Springs Dam near the Filoli estate. The route offers nearly continuous views of the expansive Crystal Springs Reservoir and the forested slopes of the Santa Cruz Mountains. A notable landmark at the trail's midpoint is the approximately 600-year-old coast redwood known as the "Jepson Laurel," one of the largest of its species in the San Francisco Bay Area.

Flora and fauna

The trail corridor is situated within a protected ecological zone characterized by a mix of riparian woodland, coastal scrub, and oak woodland habitats. Dominant tree species include coast live oak, California bay laurel, and the iconic coast redwood. The understory features native shrubs like toyon, coffeeberry, and ceanothus. This preserved habitat supports diverse wildlife, including black-tailed deer, western gray squirrel, striped skunk, and coyote. Birdlife is abundant, with frequent sightings of great blue heron, belted kingfisher, red-tailed hawk, and various species of woodpecker and songbird along the reservoir shoreline.

Recreational use

As one of the most popular multi-use trails in San Mateo County, it accommodates a wide range of non-motorized activities. The paved, gently graded surface makes it highly accessible for walking, running, inline skating, and road cycling. The trail is a favored training route for local marathon runners and cycling clubs. Its scenic, protected environment also makes it a destination for birdwatching, nature photography, and casual family outings. The San Francisco Public Utilities Commission and partner organizations occasionally host guided nature walks and environmental education programs along the corridor.

Access and facilities

Primary vehicular access is provided at the northern trailhead parking area off Skyline Boulevard and at the southern trailhead near the Crystal Springs Dam. Limited additional parking is available at the midpoint near the Jepson Laurel. The trail is open from dawn to dusk year-round, with hours enforced by the San Mateo County Sheriff's Office. Facilities are minimal to preserve the watershed; they include basic restrooms at the main trailheads, several benches, and interpretive signage detailing the area's natural and water system history. The trail is compliant with the Americans with Disabilities Act, offering an accessible outdoor experience.
