How to Use This San Gregorio, California Map
This interactive map shows the street layout and satellite imagery for San Gregorio, 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 Gregorio.
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.

About San Gregorio, California
San Gregorio is a locality in San Mateo County, California, United States. It is a small community with a population of 480. The population density is 5.0 people per km². San Gregorio is located at 37.3272°N, 122.3866°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 94074.San Gregorio reveals itself where the San Gregorio Creek carves a persistent, winding path through the landscape toward the Pacific Ocean. It lies 9.7 miles south-southeast of Half Moon Bay, CA (from Half Moon Bay, CA: bearing 166°T), and is situated 9.2 miles west-southwest of Portola Valley. This waterway acts as a verdant artery, sustaining the riparian corridors that feed into the salty air and shifting tides of San Gregorio State Beach. To the east, the horizon is anchored by the distant, hazy silhouettes of the Coast Ranges, while the immediate terrain is defined by rugged, sun-bleached slopes and sheltered creases like Long Gulch. As the light wanes, a thick, cool fog often rolls inland, softening the edges of the topography and turning the afternoon into a muted study in gray and silver.
San Gregorio maintains a quiet, agrarian character that reflects a legacy of farming and modest settlement, far removed from the frantic pace of modern centers. The local economy persists in a delicate balance with the land, emphasizing small-scale agriculture that thrives in the moisture of the creek basin. Travelers passing through often stop at the historic general store, a structure that holds the weight of decades and serves as a primary social anchor for those living among the scattered homesteads. While the nearby Mussel Rock marks the jagged edge of the shoreline, the rhythm of life in San Gregorio remains tethered to the seasonal cycles of the earth and the steady, unceasing movement of the water toward the sea.

About This San Gregorio Map Page
This page provides an embedded street and satellite map of San Gregorio, California. Coordinates: 37.327165, -122.38664. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.
Detailed location data for San Gregorio includes the ZIP code (94074), telephone area code (415, 628), county seat of San Mateo County (Redwood City), and school district assignment.
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.
