How to Use This Dennis, Massachusetts Map

This interactive map shows the street layout and satellite imagery for Dennis, 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 Dennis.

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.

About Dennis, Massachusetts

Dennis is a locality in Barnstable County, Massachusetts, United States. It has a population of approximately 2,399. The population density is 188.6 people per km². Dennis is located at 41.7354°N, 70.1939°W. It observes the Eastern Time (America/New_York) timezone. ZIP code: 02638.

Dennis reveals itself through the winding, brackish veins of Chase Garden Creek as it snakes toward the salt-heavy air of the Atlantic Ocean. It lies 2.7 miles northeast of Yarmouth, MA (from Yarmouth, MA: bearing 41°T), and is situated 5.8 miles south-southwest of Cape Cod. The low-lying terrain offers a quiet transition from the tidal flats to the clear, glacial basin of Scargo Lake, where the water mirrors the shifting gray of the sky. Far to the south, the Monomoy Island Dunes trace a faint, jagged line against the horizon, anchoring the gaze. Within the Ragozzino Property, one finds a delicate stillness where the land resists the encroachment of the modern world. The light here possesses a particular crystalline quality, sharpening the edges of the marsh grass and turning the afternoon tide into a field of hammered silver.

Maritime heritage serves as the bedrock of Dennis, tracing back to the days when salt works and shipyards defined the local economy. Though the industry has shifted toward hospitality and seasonal commerce, the connection to the water remains the primary pulse of the local trade. Residents often look to the sea for their livelihood, balancing the demands of a modern economy against the enduring legacy of early colonial enterprise. The rhythm of daily life follows the seasonal influx of visitors, yet the underlying industry maintains a steady, independent character. Far from the dense, brick-laden streets of larger cities, the work here feels tethered to the natural cycles of the coast. The local economy persists as a testament to the resilience of those who have long made their living between the harbor and the shore.

Cultural life in Dennis finds its expression in the preservation of historic architecture and the quiet appreciation of the natural surroundings. The Cape Cod Rail Trail offers a linear path for those seeking to traverse the landscape, connecting the village to the wider expanse of the peninsula. Among the notable figures associated with the broader creative spirit of this region, the writer Mary Higgins Clark maintained a presence that resonates with the local literary tradition. The Ragozzino Property stands as a testament to the commitment to conservation, ensuring that the wilder textures of the land remain accessible to all. Evenings often center on the small, communal gatherings that define the social fabric, far removed from the clamor of professional sports or massive urban institutions. Dennis maintains a distinct identity, marked by a literate, unassuming pride that values the slow turning of the seasons above all else.

About This Dennis Map Page

This page provides an embedded street and satellite map of Dennis, Massachusetts. Coordinates: 41.735387, -70.193909. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Dennis includes the ZIP code (02638), telephone area code (339, 351, 413, 508, 617, 774, 781, 857, 978), county seat of Barnstable County (Barnstable), and school district assignment (Dennis-Yarmouth School District).

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.
