How to Use This San Antonio, Puerto Rico Map
This interactive map shows the street layout and satellite imagery for San Antonio, Puerto Rico. 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 Puerto Rico 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.
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, Puerto Rico
San Antonio is a locality in Añasco County, Puerto Rico, United States. San Antonio is located at 18.0800°N, 66.9732°W. It observes the Atlantic Standard Time — no DST (America/Puerto_Rico) timezone. ZIP code: 00603.San Antonio emerges from the low-lying plains where the Río Dagüey carves a persistent, silver path toward the horizon. It lies 9.9 miles south of Aguadilla, PR (from Aguadilla, PR: bearing 174°T), and is situated 7.3 miles south-southeast of Aguada. The landscape surrounding San Antonio is defined by a lush, humid permeability, where the earth yields easily to the winding watercourse and the encroaching shadow of the Quebrada Abad. To the east, the silhouette of La Cadena rises against the sky, a distant, jagged reminder of the rugged spine that anchors the island. The air here holds the heavy, sweet scent of damp soil and ripening vegetation, a sensory testament to the tropical climate that keeps the vegetation in a state of perpetual, verdant motion. Even the light seems to possess a different weight, shifting from a sharp, clear gold at midday to a softened, bruised violet as evening approaches, casting long, contemplative shadows over the flat expanse.
History in San Antonio remains tied to the quiet, rhythmic labor of the land, where the economy has long leaned into the cultivation of the surrounding fields and the modest commerce of a people who understand the value of patience. Residents move with a deliberate grace, their daily routines punctuated by the distant, rhythmic hum of progress and the proximity of the Bahía de Añasco, whose salt-kissed breezes drift inland to temper the heat. Life here is lived in the intervals between the work of the day and the sanctuary of the Unknown Local Park, a quiet stretch of green where the community gathers to watch the clouds gather over the distant peaks. Those who seek movement often find their way to the Vereda Caracol, a path that invites a steady, measured pace through the undergrowth, offering a brief, solitary communion with the persistent, untamed spirit of the terrain.

Detailed location data for San Antonio includes the ZIP code (00603), telephone area code (787, 939), county seat of Añasco County, 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.
