Pulgas Water Temple Area Exploration is a 4.1 mile out and back trail located near Redwood City, CA that features a lake. The trail is good for all skill levels and primarily used for hiking, walking, and nature trips.
The Pulgas Water Temple was built at the terminus of the Hetch Hetchy aqueduct as a monument to the new water system. It's located within the watershed, just south of Crystal Springs reservoir. An inscription at the top reads, "I give waters in the wilderness and rivers in the desert, to give drink to my people," a biblical quote from Isaiah. The San Francisco Peninsula Watershed, managed by the San Francisco Public Utilities Commission, is home to trails that offer access to remote wilderness, Northern California geology, and opportunities to enjoy ridge-top vistas of our watershed lands, reservoirs, the Pacific Ocean and San Francisco Bay. The newly-opened portion of the SFPUC Peninsula Watershed's Fifield-Cahill Ridge Trail, accessible through guided tours, starts at Skyline Quarry on Highway 92 and extends northward to the watershed boundary at the Portola Ridge Gate.
