Lagunitas-Forest Knolls, Census-designated place in Marin County, United States.
Lagunitas and Forest Knolls are two residential communities nestled in western San Geronimo Valley, where homes sit among wooded hillsides and creeks. The combined area features winding roads that follow natural terrain, creating neighborhoods that blend into the surrounding forest landscape.
Forest Knolls established a post office in 1916, marking the start of formal settlement in this valley community. The two areas developed afterward as rural settlements, eventually transforming into residential neighborhoods as the region grew.
The residents here share a strong commitment to environmental stewardship and take pride in caring for the creeks that flow through their homes. This connection to nature shapes how people in the area live and interact with each other.
The area sits right next to Samuel P. Taylor State Park, providing easy access to trails for walking and riding. Visitors should wear sturdy shoes since the terrain is hilly and can be uneven in places.
San Geronimo Creek flows through both communities and hosts one of the last spawning grounds for endangered Coho salmon in Central California. This waterway plays a vital role in keeping this fish population alive.
