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 Caguas 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 occupies a quiet reach of the interior landscape where the land shifts into a complex geometry of slopes and verdant depressions. It lies 1.4 miles east-northeast of Caguas, PR (from Caguas, PR: bearing 62°T), and is situated 9.5 miles southeast of Guaynabo. The Río Caguitas carves a deliberate path through the terrain, its waters animating the earth with a steady, liquid persistence that defines the local topography. To the north, the silhouettes of the Altos de San Luis rise with a jagged, gray clarity against the afternoon sky, while the nearby Quebrada Las Bambúas deepens the basin into a fertile, shadowed hollow. Here, the air holds a heavy, humid stillness that settles over the Unknown Local Park, grounding the environment in a sense of permanence that feels detached from the rapid movement of the modern world.
History in San Antonio resonates through the persistent labor of those who have long worked these inland fields, maintaining an economy tied to the rhythms of the soil and the seasonal shifts of the tropical climate. The local character is marked by a quiet, enduring industry, far removed from the transient pressures of the coast, as residents maintain a life defined by the immediate physical reality of the central highlands. While the distant El Rada Trail offers a rare passage through the more rugged reaches of the region, the daily experience of the population remains centered on the modest, functional architecture and the steady, unadorned progress of their trade. In the waning light of dusk, the transition between the vibrant green of the vegetation and the darkening ridges creates a visual clarity that makes San Antonio feel like a singular, concentrated point of existence in the vast, mountainous interior.

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