The only exceptions are on winter holiday Sundays or during inclement weather. The route traverses Peninsula foothill country lined with grasslands and oaks, but its most striking feature is its views of Upper Crystal Springs Reservoir, the hidden paradise of the San Francisco watershed. The road also leads past the Pulgas Water Temple. This Romanesque structure is where the San Francisco Water District celebrates the terminus of the Hetch Hetchy aqueduct, bringing water over 200 miles by canal from Yosemite. Less than a half-mile from the Pulgas Water Temple is the Filoli Estate, a historic 1917 mansion and 16 acres of spectacular formal gardens.
Tours are available by reservation on some Sundays.
