How to Use This San Antonio Heights, California Map
This interactive map shows the street layout and satellite imagery for San Antonio Heights, 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 Antonio Heights.
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 Antonio Heights, California
San Antonio Heights is a locality in San Bernardino County, California, United States. It has a population of approximately 3,441. The population density is 543.2 people per km². San Antonio Heights is located at 34.1556°N, 117.6564°W. It observes the Pacific Time (America/Los_Angeles) timezone. ZIP code: 91784.San Antonio Heights rises where the flat plains yield to the rugged incline of the earth, defined by the jagged descent of Frankish Canyon. It lies 4.0 miles north of Upland, CA (from Upland, CA: bearing 353°T), and is situated 6.4 miles north of Ontario. The air here holds a crisp, thin quality, cooling rapidly as the shadows of the distant San Gabriel Mountains stretch across the slope at dusk. To the west, the arid terrain is marked by the presence of Angeles National Forest, where the wild, untamed vegetation resists the encroaching heat of the lowlands. Cucamonga Creek cuts a narrow, seasonal path through the gravelly soil, an ephemeral vein of water that remains silent for much of the year, waiting for the winter rains to stir the dry riverbed into motion.
San Antonio Heights retains the quiet character of its early agricultural roots, when the land was primarily shaped by the labor of citrus groves and the patient work of early settlers. While the economy has shifted toward residential life and professional service, the original grid of the landscape remains, preserving a sense of stillness that contrasts with the bustle of the distant metropolitan basin. Residents often find their way to the West Cucamonga Truck Trail, a path that offers a vantage point over the dry, gold-hued expanse below, far removed from the damp atmosphere found near Puddingstone Reservoir. Life in San Antonio Heights moves at a deliberate pace, colored by the intense, amber light that settles over the chaparral, turning the evening sky into a canvas of muted violet and gray.

About This San Antonio Heights Map Page
This page provides an embedded street and satellite map of San Antonio Heights, California. Coordinates: 34.155564, -117.656444. 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 Antonio Heights includes the ZIP code (91784), telephone area code (818, 747), county seat of San Bernardino County (San Bernardino), and school district assignment (Upland Unified School District).
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.
