About

Fountaingrove

Fountaingrove, located between Highway 101 and Annadel State Park, is a hillside and master-planned Santa Rosa neighborhood with golf-course greens and ridge-top views. The neighborhood’s character concentrates around the Fountaingrove Parkway and Thomas Lake Harris Drive junction, where landscaped medians, trailheads, and a steady flow of cyclists set a polished, outdoors-forward tone. Housing leans contemporary and Mediterranean-influenced, with newer builds and rebuilt enclaves shaped by the area’s recent history. The Fountaingrove Club anchors the social calendar with fairways and dining. For arts and local flavor nearby, Luther Burbank Center for the Arts and Russian River Brewing Company in town act as familiar gathering points. Oak-studded open space and winding streets keep the pace calm while still feeling connected to Santa Rosa’s core.
