About

Carolands

Carolands, located between El Camino Real and Skyline Boulevard, is a residential and estate-style Hillsborough neighborhood with grand historic mansions and winding, tree-lined lanes. The neighborhood’s character concentrates around the Carolands Chateau, where formal gardens and gated drives set a quiet, museum-like tone. Architectural cues lean Beaux-Arts and Mediterranean Revival, with long setbacks and curated landscaping. The setting feels tucked into the Peninsula’s foothill edge, with filtered bay views from higher streets. Nearby Burlingame Avenue adds a polished café-and-boutique rhythm without changing Carolands’ hush. Trails and open space at the edge of the hills shape a weekend walking routine.
