Explore Sister Bay, Wisconsin, 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 Sister Bay, Wisconsin. 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 Wisconsin 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 Sister Bay.
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.

Sister Bay stretches its timbered docks and limestone shorelines along the deep, cool expanse of Lake Michigan. It lies 6.4 miles northwest of Door, WI (from Door, WI: bearing 326°T), and is situated 25.6 miles east-northeast of Marinette. The water of Sister Bay settles into a quiet harbor, reflecting the pale, thin light of late afternoon as the horizon blurs into a soft, monochromatic gray. Beyond the immediate waterfront, the landscape rises into dense woodlands that hide the winding course of Three Springs Creek, a vital artery of cold, clear water feeding the broader basin. Far to the south, the distant, hazy spine of the Door-Leelanau Ridge marks the edge of the world, while the jagged Sister Islands sit like scattered stones upon the surface of the lake, silent sentinels watching over the shifting currents.
History remains etched in the Scandinavian roots of Sister Bay, where the legacy of early maritime settlers lingers in the sturdy architecture and the local devotion to the Friday fish fry. The economy relies on the seasonal pulse of the lake, drawing travelers who wander through the nearby quietude of North Bay to witness the transition of the seasons. Life in Sister Bay moves with the deliberate pace of a place defined by its edges, where the air smells of pine needles and damp cedar, and the rhythm of the day is dictated by the slow, inevitable turn of the tides against the harbor walls.

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.
