Explore Gilgo, New York, with this interactive street and satellite map.
This page also offers TOPO MAPS — the official USGS topographic sheets — plus USGS aerial imagery, a labelled USNG grid overlay, a distance and bearing tool, and a GPS grid-reference readout. See How to Use This Map below.
This interactive map shows the street layout and satellite imagery for Gilgo, New York. 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 New York 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 Gilgo.
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.

Gilgo stretches across a thin, sandy expanse where the horizon dissolves into the restless gray expanse of the Atlantic Ocean. It lies 4.0 miles south-southeast of Lindenhurst, NY (from Lindenhurst, NY: bearing 155°T), and is situated 9.5 miles southwest of Islip. The landscape is defined by the shifting dunes and salt-sprayed grasses of Gilgo State Park, a protected sanctuary that acts as a fragile barrier between the surging tides and the mainland. To the north, the salt marshes provide a quiet, brackish threshold, while the presence of Cedar Island just offshore breaks the monotony of the open water. On clear, crisp days, the distant silhouette of the Appalachian Mountains remains a faint, ghostly suggestion far to the west, though the immediate world here is one of wind, brine, and the relentless, rhythmic percussion of the surf against the shore.
Life in Gilgo is dictated by the seasonal pulse of the coast, far removed from the inland stillness of Argyle Lake or the quiet flow of Neguntatogue Creek. The economy remains tethered to the environmental stewardship of the park, preserving a landscape that has historically served as a rugged buffer against the fury of the storms. Residents and visitors alike navigate a space where the debris of the tide often tells more of the past than any formal record, leaving behind a sense of isolation that feels both intentional and absolute. It is a place where the light at dusk flattens the dunes into sharp, violet shadows, grounding the observer in a terrain that refuses to be tamed by the suburban sprawl pressing in from the north.

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.
