Explore Greencastle, 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 Greencastle, 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 Greencastle.
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.

Greencastle emerges from the fertile limestone plains as a collection of brick facades and orderly streets that catch the soft, amber light of late afternoon. It lies 2.3 miles north of Antrim Township, PA (from Antrim Township, PA: bearing 353°T), and is situated 8.3 miles west-northwest of Waynesboro. Paddy Run winds its way through the periphery, a quiet artery of water that marks the transition from the manicured lawns of Jerome R. King Playground to the broader, working landscape of the Cumberland Valley. To the west, the distant, hazy blue silhouettes of the Appalachian Mountains anchor the horizon, standing as silent observers to a geography defined by wide fields and the dense, dark green canopy of Mont Alto State Forest just a short distance to the east. The air here holds the scent of damp earth and alfalfa, a persistent reminder of the agricultural rhythms that continue to dictate the pace of the day.
Greencastle carries a legacy of mid-Atlantic settlement, where the architecture reflects a steady, pragmatic evolution from frontier crossroads to a place of industry and trade. While the proximity to Blair Valley underscores the topographic complexity of the region, the local economy remains tethered to the productivity of the surrounding soil and the steady flow of commerce along the transit corridors that have shaped the region since its founding. Life moves with a deliberate, measured cadence, punctuated by the seasonal labor of the harvest and the quiet maintenance of the local infrastructure. Even the Greencastle Reservoir, sitting in its still, reflective basin, seems to mirror this sense of functional endurance, offering a calm, utilitarian presence that anchors the outer edges of the landscape against the shifting pressures of the modern world.

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.
