Explore St. Helena, California, 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 St. Helena, California. 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 California 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 St. Helena.
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.

St. Helena emerges from the landscape as a collection of sun-drenched structures bordered by the persistent, rhythmic flow of Sulphur Creek. It lies 13.9 miles east-northeast of Santa Rosa, CA (from Santa Rosa, CA: bearing 71°T), and is situated 7.8 miles southeast of Calistoga. Beyond the immediate town limits, the terrain shifts into the rugged, quiet elevations of the Coast Ranges that stand as distant sentinels on the horizon. To the west, the landscape deepens into the shadows of Heath Canyon, where the light catches the dust of the dry season in long, amber streaks. Residents often find solace in the proximity of Bell Canyon Reservoir, which mirrors the vast, cloudless sky during the heat of the afternoon. The open land here favors the growth of oak savanna, maintaining a connection to the wilder, uncultivated stretches of the interior.
St. Helena carries the weight of a long agricultural legacy that defines the daily movement of its commerce and labor. The economy relies heavily on the cultivation of the soil, with rows of vines stretching across the valley floor in precise, mathematical lines. Historically, the area grew from these agrarian roots, establishing a reputation for a specific quality of output that remains central to its identity. Local industry operates in silence, punctuated by the seasonal demands of harvest and the slow, deliberate processing of the yield. The rhythm of the work reflects the climate, where the golden summer heat forces a slower, more intentional pace upon those who tend the fields.
St. Helena maintains a cultural character defined by a quiet, deliberate sophistication that values the preservation of its physical surroundings. Lyman Park serves as the central gathering point for the populace, providing a shaded expanse where the pace of the day seems to pause under the heavy canopy. For those seeking the solitude of the woods, the Headwaters Trail offers an ascent into the local topography, eventually leading toward the cooling mist of Linda Falls. Famous residents such as Robert Louis Stevenson once walked these same paths, finding inspiration in the interplay of shadow and light across the terrain. Public life moves with a steady, predictable gravity, grounded by the landmarks that have defined the experience of this locality for generations.

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.
