Floor Plans


Family-friendly Mill Valley is all about schools and sports. Nestled at the foot of Mount Tamalpais, homes in the Marin County city range from 500-square-foot hunter's cabins to multimillion-dollar mansions tucked away on winding, narrow lanes under the redwoods. Coffee is king in Mill Valley. Downtown, three separate coffee shops do a brisk business. At the Depot, as the sunny town center is called, moms with strollers, kids on tricycles, and teenagers kicking hacky sacks relax in the open-air plaza, which now houses an independent bookstore and cafe. The Depot is also a jumping-off spot for hikers and mountain bikers heading up the slopes of Mount Tamalpais. Nightlife in Mill Valley is anchored by Sweetwater Music Hall, which hosts many well-known musical acts. As the groomed playing fields at the community center attest, sports are big in Mill Valley, with soccer, baseball, and lacrosse leagues all popular.
