Alto, CA

Alto is a small, quiet community tucked right alongside Mill Valley in southern Marin County. Because it sits on unincorporated county land, it has its own distinct neighborhood feel, but daily life here is closely tied to its neighbor. Most homes share a Mill Valley postal address, and residents head into town for local dining, grocery runs, and nearby parks. It is also an especially practical spot for commuters, offering quick access to Highway 101 and the rest of the Bay Area alongside the scenic, tree-lined surroundings Marin is known for. It works well as a relaxed home base with Mill Valley conveniences right down the road.
