Explore Donegal, Pennsylvania, 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 Donegal, Pennsylvania. 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 Pennsylvania 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 Donegal.
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.

Donegal occupies a high, quiet shoulder of the landscape where the air thins and sharpens against the skin. It lies 15.4 miles south-southeast of Greensburg, PA (from Greensburg, PA: bearing 148°T), and is situated 8.7 miles east-southeast of Mount Pleasant Westmoreland County. Sunlight here catches the edges of the hardwoods, illuminating the deep green swaths of Forbes State Forest that anchor the horizon ten miles to the east. The terrain defines itself through a series of persistent, rhythmic swells, leading the eye toward the distant, hazy silhouette of the Allegheny Mountains far to the southeast. Minnow Run carves a modest, silver-threaded path through the earth just a mile away, its presence marked by the low, constant hum of water against stone, while the cool, still surface of Lake Donegal rests two miles out, a mirror for the shifting gray clouds that drift across the plateau.
Donegal carries the weight of a working history, shaped by the steady, persistent labor of those who cleared these woods and tilled the stubborn soil. Local life flows with a deliberate pace, far removed from the clamor of the heavy industrial basins, finding its recreation in the quietude of Chestnut Ridge Park, which sits two miles away. Beyond the immediate fields, the deep, shadowed silence of Possum Hollow remains a defining feature of the geography, echoing with the memory of early travel before the paved roads arrived. Those seeking the rugged pulse of the wilderness often find their way to Adams Falls, nine miles distant, or test their endurance on the Darr Trail ten miles away, where the forest floor holds the damp, earthy scent of ancient pine.

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.
