Explore San Carlos, 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 San Carlos, 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 San Carlos.
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.

San Carlos holds a distinct position upon the landscape where the land begins to soften toward the Pacific Ocean. It lies 1.2 miles southeast of Belmont, CA (from Belmont, CA: bearing 137°T), and is situated 5.3 miles southeast of San Mateo. Pulgas Creek meanders through the terrain, tracing a quiet path that defines the local topography and guides the flow of seasonal runoff. To the west, the Coast Ranges rise against the horizon, their silhouettes shifting in color as the afternoon sun retreats. Residents often walk the paths near Laureola Park, where the air retains a crisp, maritime clarity carried inland by the prevailing breezes. Beyond the urban grid, the terrain rises toward the rugged textures of McGarvey Gulch, while Bair Island marks the nearby low-lying reaches where the water meets the shore.
San Carlos emerged from the steady expansion of the peninsula, growing from small-scale agricultural roots into a center of suburban enterprise. The local economy has evolved from its early reliance on the land to become a hub for technology and light industry, drawing energy from the nearby transit corridors. Small businesses and professional offices define the commercial streets, reflecting a shift toward a service-oriented and intellectual workforce. Over the decades, the character of the economy has mirrored the broader trends of the region, favoring innovation and the development of specialized workspaces. Even as industry modernized, the town maintained its original street layout, preserving a sense of historical continuity amidst the rapid pace of change.
San Carlos fosters a quiet, deliberate character that is reflected in the well-tended gardens and the frequent gatherings held at Laureola Park. The community life centers on local schools and the bustling downtown, where the rhythm of the day feels measured and intentional. Edgewood Trail provides a necessary connection to the natural world for those seeking a respite from the suburban sprawl, offering passage through the local oak savanna. While few figures of global renown claim the area as their primary residence, the spirit of the place is shaped by the people who value a balance between professional ambition and personal tranquility. On clear evenings, the light catches the gray hues of the distant Coast Ranges, casting a long, golden shadow that signals the end of another day in San Carlos.

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.
