About
Marinwood
Marinwood, located between Miller Creek and Lucas Valley Road, is a residential and hillside Lucas Valley-Marinwood neighborhood with mid-century ranch homes and oak-dotted open space. The neighborhood’s character concentrates around the Marinwood Plaza area on Miller Creek Road, where a low-key strip of local shops and everyday errands sets the tempo. Community pillars include Marinwood Market, Marinwood Community Center, and the Marinwood–Lucas Valley Library. Streets curve along gentle slopes, with many homes oriented to ridgelines and valley views. Sidewalk strolls and bike loops connect to trailheads and playing fields, giving daily routines a outdoors-forward rhythm. The setting feels tucked into the North Bay’s greenbelt, with Highway 101 close by but visually buffered by trees and terrain.
