Explore Mill Valley, California, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Mill Valley, California. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of California or beyond.
Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Mill Valley.
Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Mill Valley emerges from the shadow of the Coast Ranges, which loom distantly on the horizon like a weathered spine of ancient earth. It lies 1.6 miles southwest of Corte Madera, CA (from Corte Madera, CA: bearing 215°T), and is situated 4.7 miles south of San Rafael. Old Mill Creek carves a meditative path through the landscape, its waters catching the fleeting, pale gold of the afternoon sun as they slide toward the nearby Pacific Ocean. The residents of Mill Valley walk beneath a canopy of native trees, often finding respite in the quiet green shade of the Mill Valley Town Center City Park. Warner Canyon folds the land into deep, sheltered pockets, where the air holds the scent of damp earth and the encroaching salt of the sea. Only a few miles away, the steady rush of Kent Falls provides a rhythmic pulse to the rugged terrain. Travelers often wander the Cowboy Rock Trail to touch the raw, unpolished face of the hillside, feeling the immense scale of the geography beneath their feet.
Mill Valley evolved from a landscape of timber and industry into a sanctuary for those seeking the stillness of the northern California woods. The early economy relied heavily on the harvest of redwood, leaving a legacy of sawmills that once defined the rhythm of daily labor. Today, the economic landscape has shifted toward specialized services and a vibrant local commerce that sustains the residents of Mill Valley without compromising its quietude. The proximity to the Pacific Ocean continues to influence the ebb and flow of regional trade, even as the town maintains its focus on preservation and local character. Silva Island remains a distant, silent witness to the changes in the harbor, standing apart from the busyness of the mainland. Industry here is now measured in the careful maintenance of the environment and the cultivation of a thoughtful, intentional way of life.
Cultural life in Mill Valley reflects an affinity for the arts and a profound respect for the natural world that frames every street. The Mill Valley Town Center City Park serves as an anchor for the community, hosting gatherings that bring a sense of shared purpose to the quiet, tree-lined thoroughfares. Notable figures, such as the musician Sammy Hagar, have found a creative home here, drawn by the unique clarity of the coastal light and the privacy afforded by the surrounding woods. Local events often celebrate the intersection of creative expression and environmental stewardship, grounding the residents in their specific corner of the world. While the influence of Sutro Forest is felt in the cool, moisture-laden breezes that drift through the canyons, the spirit of the place remains distinctly its own. Life moves with a deliberate pace, colored by the gray fog that rolls in from the Pacific Ocean to soften the edges of the day.

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.
Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
