How to Use This Port San Luis, California Map

This interactive map shows the street layout and satellite imagery for Port San Luis, 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 Port San Luis.

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 Port San Luis, California

Port San Luis is a locality in San Luis Obispo County, California, United States. It is a small community with a population of 480. The population density is 18.0 people per km².

Port San Luis holds the rugged edge of the continent where the land yields abruptly to the Pacific Ocean. It lies 8.4 miles west-northwest of Grover Beach, CA (from Grover Beach, CA: bearing 296°T), and is situated 9.2 miles southwest of San Luis Obispo. The character of the landscape is defined by the salt-heavy air and the rhythmic, percussive slap of tides against the pilings that anchor the harbor to the shoreline. Within the boundaries of Old Port Beach, the terrain remains raw and exposed, a place where the fog often lingers like a ghost over the water, softening the sharp outlines of the cliffs. Just a mile away, the quiet flow of San Luis Obispo Creek cuts through the earth, winding past the deep shadows of Wild Cherry Canyon before meeting the sea, while the rocky silhouette of Smith Island rests in the near distance, a silent sentinel watching over the shifting currents.

History at Port San Luis is written in the weathered timber of the piers and the persistent labor of those who draw their living from the deep. The local economy persists as a quiet mosaic of commercial fishing and maritime activity, maintaining a pace that ignores the frantic speed of the modern world. While the distant Coast Ranges remain visible as a hazy, jagged line against the horizon, the daily rhythm here is governed by the arrival of boats and the seasonal pulse of the tides. Travelers who venture far enough to find the solitude of this coast might look toward the horizon, perhaps considering the long hike to the Alan Peak Trail, yet most find that the simple gravity of the harbor, with its blend of industrial grit and Pacific light, provides enough to satisfy the eye.

About This Port San Luis Map Page

This page provides an embedded street and satellite map of Port San Luis, California. Coordinates: 35.174975, -120.755176. 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 Port San Luis includes the ZIP code (93424, 93420), telephone area code (805), county seat of San Luis Obispo County (San Luis Obispo), and school district assignment.

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.
