Emerald Lake Hills, Census-designated place in San Mateo County, California.
Emerald Lake Hills is a residential census-designated place in San Mateo County located between Woodside and Redwood City, California. The area spreads across oak-covered slopes where homes sit individually within the natural landscape rather than forming a compact settlement.
The area originated from a Rancho de las Pulgas land grant dating back to 1795. It developed as a residential community after World War I, with two subdivisions established around 1920.
The two lakes define the area's character, with Lower Emerald Lake serving as a social hub and Upper Emerald Lake remaining secluded on private grounds. Residents gather around these water features that shape daily life and community identity in the hills.
The area sits on hillside terrain, so walking or driving are the best ways to explore the neighborhoods. Visitors should expect winding roads and varying elevation throughout the region.
Handley Rock Park holds San Mateo County's largest sandstone monolith, protected and maintained by a local group dedicated to conservation. This natural landmark attracts visitors curious about the geology and outdoor features of the region.
