Explore Greenbrae, 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 Greenbrae, 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 Greenbrae.
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.

Greenbrae emerges from the tidal margins where the silt-heavy currents of Corte Madera Creek trace a rhythmic, brackish path toward the wider expanse of the Pacific Ocean. It lies 1.1 miles north-northeast of Larkspur, CA (from Larkspur, CA: bearing 30°T), and is situated 9.7 miles west of Richmond. The landscape here is defined by a gentle, sloping topography that descends from the higher elevations toward the water, where the salt-tinged air frequently carries a thick, cool fog that obscures the distant, serrated silhouettes of the Coast Ranges. Within the immediate vicinity, Corte Los Sombras Park offers a quiet sanctuary of greenery, providing a sharp, verdant contrast to the manicured residential streets that climb the hillsides. Residents often find themselves looking toward the nearby Ross Valley, where the air holds a different, inland warmth, or observing the singular, marshy presence of Wood Island as it rests amidst the shifting, gray-blue tides.
Economic vitality in Greenbrae has long been tethered to its strategic position between the urban centers and the wilder, northern reaches of the region, evolving from its mid-century development into a center of professional life and suburban stability. The daily commerce flows along the arterial roads that mirror the path of the creek, sustaining a local economy that thrives on the pulse of commuters and the refined requirements of its inhabitants. Beyond the immediate bustle, the geography invites a slower pace, whether one is seeking the elevation of the Huckleberry Trail or the quiet, still surface of the Forbes Hill Reservoir. When the late afternoon sun strikes the water, the light possesses a distinct, pale gold clarity that illuminates the reeds and the distant, dark form of the water, suggesting a place that remains deeply attuned to the natural pressures of the tide and the slow, seasonal shifts of the earth.

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.
