San Geronimo, the namesake of the valley the town is located in, is an unincorporated town in Marin. Like Woodacre and all the other towns in the valley, it is surrounded by nature. San Geronimo Valley Community Center is located here as well as San Geronimo Valley Elementary School, both serving the semi-rural communities of Woodacre, San Geronimo, Forest Knolls, and Lagunitas. Also located here is Roy’s Redwood Preserve, a local hiking destination offering some great trails.
