How to Use This Las Marías, Puerto Rico Map
This interactive map shows the street layout and satellite imagery for Las Marías, 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 Las Marías.
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 Las Marías, Puerto Rico
Las Marías is a locality in Salinas County, Puerto Rico, United States. Las Marías is located at 17.9892°N, 66.2692°W. It observes the Atlantic Standard Time — no DST (America/Puerto_Rico) timezone.Las Marías occupies a landscape where the earth rises in deep, verdant swells, shaped by the relentless work of the Río Nigua as it cuts through the terrain. It lies 10.2 miles west of Guayama, PR (from Guayama, PR: bearing 272°T), and is situated 8.6 miles southeast of Coamo. The air here carries a heavy, persistent moisture that clings to the skin, cooling only when the light begins to fail near the slopes of Cerro Modesto. From the high points, one can catch the faint, shimmering influence of the Bahía de Rincón in the distance, a reminder of the proximity to the open water that governs the humidity of the region. Below the ridges, the land folds into the basin of Quebrada Honda, creating a natural bowl that holds the morning mist long after the sun has climbed high. A short distance away, the Parque de Salinas offers a localized respite of greenery, providing a contrast to the wilder, unmanaged growth that creeps along the banks of the river.
Las Marías retains the quiet character of an agricultural outpost, defined by a history rooted in the careful cultivation of the soil. The local economy relies on the stubborn persistence of small-scale farming, where the rhythm of the work is dictated by the seasonal rains and the slow maturation of harvests. Residents move with a deliberate pace, acknowledging the long-standing tradition of self-reliance that has defined the character of the inhabitants for generations. While the influence of larger, more frantic centers of commerce remains distant, the people maintain a distinct sense of their place in the world, observing the subtle shifts in the tide of daily life. Even as the modern world encroaches, the quiet persistence of the land ensures that the identity of Las Marías remains anchored to the earth and the water that sustains it.

Detailed location data for Las Marías includes the ZIP code, telephone area code, county seat of Salinas 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.
