How to Use This Port Mansfield, Texas Map

This interactive map shows the street layout and satellite imagery for Port Mansfield, Texas. 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 Texas 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 Port Mansfield.

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.

Port Mansfield exists as a low-slung expanse where the horizon dissolves into the pale, salt-crusted edges of the coast. It lies 22.7 miles east-northeast of Raymondville, TX (from Raymondville, TX: bearing 77°T), and is situated 30.2 miles north-northeast of Harlingen. The landscape here is defined by a flat, sun-bleached austerity, where the distant silhouette of Green Hill provides the only significant break in an otherwise level prairie that stretches toward the shimmering waters of Red Fish Bay. To the north, the terrain remains sparse and windswept, a place where the air carries a constant, briny weight and the light at dusk turns the shallow tidal flats into sheets of bruised copper. Near the water, the topography gives way to the low, shifting profiles of El Sauz Island, which stands as a silent sentinel against the pulse of the tides.

Port Mansfield functions as a secluded waypoint for those drawn to the solitude of the water, its economy tethered tightly to the rhythm of the tides and the seasonal migration of anglers. While the nearby Small Community Park offers a modest space for reflection, the true pulse of the area is found in the weathered docks and the quiet, persistent industry of the fishing trade. Inland, the geography shifts toward the arid, scrub-filled expanse of Plan de Monterrey, while the ecological reach of the region extends as far as the distant waters of Laguna Atascosa. Life here moves with a deliberate, unadorned cadence, far removed from the sprawl of the interior, underscored by the occasional flow of the East Main Drain as it marks the subtle shifts in the surrounding plains.
