How to Use This Alianza, Puerto Rico Map
This interactive map shows the street layout and satellite imagery for Alianza, 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 Alianza.
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 Alianza, Puerto Rico
Alianza is a locality in Camuy County, Puerto Rico, United States. It has a population of approximately 1,910. The population density is 802.9 people per km². Alianza is located at 18.4516°N, 66.8535°W. It observes the Atlantic Standard Time — no DST (America/Puerto_Rico) timezone. ZIP code: 85351.Alianza emerges from the verdant, humid lowlands where the air holds a persistent, salt-tinged weight that drifts in from the distant Puerto Arecibo. It lies 9.1 miles west of Arecibo, PR (from Arecibo, PR: bearing 261°T), and is situated 5.8 miles east-southeast of Quebradillas. Beyond the immediate horizon, the Montañas Guarionex rise like a jagged, shadowed spine, their slopes catching the heavy afternoon light before it settles into the depths of Quebrada Bellaca. The land here is defined by the steady, rhythmic passage of the Río Camuy, which carves a path through the limestone earth, its waters cool and dark against the sun-baked soil. To the north, the sharp silhouette of Peñon Brusi stands solitary against the tides, a sentinel watching over the coastal transition where the tropical brush yields to the encroaching influence of the sea.
Alianza maintains a deliberate, measured pace, anchored by the quietude of the Unknown Local Park where residents gather as the heat of the day recedes. The local economy persists in a delicate balance between the legacy of small-scale agriculture and the modern necessity of a shifting labor market, often looking toward the interior coffee country for its historical sense of self. Life here remains tethered to the land’s natural rhythms, whether one is navigating the verdant expanse toward the Bosque Estatal de Guajataca or observing the migration of birds far closer to the Vereda de las Cotorras. Even as the modern world presses against the edges of the landscape, the people of Alianza carry a distinct, dual awareness of their island home—a profound attachment to this specific soil coupled with an expansive, outward-looking perspective that reaches well beyond the shoreline.

Detailed location data for Alianza includes the ZIP code (85351), telephone area code (787, 939), county seat of Camuy 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.
