Explore Belmont, Massachusetts, 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 Belmont, Massachusetts. 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 Massachusetts 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 Belmont.
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.

Belmont rises across the undulating landscape with a quiet, deliberate grace that defines its suburban horizon. It lies 1.7 miles north of Watertown, MA (from Watertown, MA: bearing 7°T), and is situated 6.6 miles west-northwest of Greater Boston. The terrain here holds a subtle tension, caught between the dense terrestrial weight of the land and the distant, salt-tinged pull of the Atlantic Ocean five miles away. Claypit Pond rests in the lower reaches of the local topography, its surface often mirroring the pale, shifting light of a coastal sky. To the west, the Middlesex Fells ripple across the skyline, while the gentle flow of Beaver Brook carves a narrow, persistent path through the earth. Within the Mclean Hospital Open Space, the land remains largely undisturbed, preserving a sense of wild, unmanicured solitude that anchors the surrounding residential streets.
Belmont traces its early roots to the agrarian traditions of the Massachusetts Bay Colony, where the soil once yielded harvests that sustained a growing population. Over time, the local economy shifted from the plow to the intellectual and professional pursuits that now characterize the region’s steady industry. While the bustling commerce of nearby urban centers dictates the pace of the daily commute, Belmont retains a focus on educational excellence and specialized medical research. The legacy of the nineteenth-century landscape architects who shaped much of the local design is still visible in the deliberate layout of the older neighborhoods. This commitment to thoughtful development has allowed the area to maintain a disciplined, industrious character that values long-term stability over rapid, ephemeral expansion.
Cultural life in Belmont thrives through a collective appreciation for the arts and a quiet, literate engagement with the world. Residents often gather near the Mclean Hospital Open Space to enjoy the changing seasons, finding beauty in the way the autumn light filters through the trees. The town is recognized for its historic architecture, which includes stately homes that speak to a long-standing tradition of local craftsmanship. Notable individuals like the architect Walter Gropius once found inspiration in this environment, contributing to the distinct, modern aesthetic that punctuates the traditional streetscapes. Though the Black Heritage Trail lies six miles away, the intellectual spirit of the region remains deeply connected to the broader history of the Commonwealth. Life here moves with a measured, intentional rhythm, reflecting a community that balances its deep-rooted heritage with a forward-looking perspective.

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.
