Explore Castaic, 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 Castaic, 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 Castaic.
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.

Castaic emerges from the sun-bleached earth as a landscape defined by the quiet tension of dry, golden hills and deep, shadow-filled depressions. It lies 3.2 miles north-northwest of Valencia, CA (from Valencia, CA: bearing 346°T), and is situated 8.1 miles northwest of Santa Clarita. Castaic Creek carves a seasonal path through the basin, marking the low ground where the soil holds the memory of winter rains. To the north, the terrain rises toward the distant San Gabriel Mountains, which stand as a jagged, violet silhouette against the afternoon haze. The proximity of Charlie Canyon creates a natural funnel for the wind, which moves across the dry grasses with a low, persistent hum. Near the water’s edge at Castaic Lagoon, the air cools, offering a brief respite from the relentless heat that defines the long California summers.
Castaic holds a history rooted in the necessity of transit, serving as a vital passage for those moving through the rugged interior of the state. The local economy finds its footing in the steady pulse of the freeway, supported by industries that cater to the traveler and the logistics of a growing region. Del Valle Park serves as a quiet center for the inhabitants, providing a patch of managed green that stands in stark contrast to the surrounding arid expanse. Agriculture once claimed these slopes, leaving behind a legacy of resilience that persists in the modern arrangement of local commerce. Development has slowly filled the gaps between the ridges, yet the underlying character of the land remains tethered to the infrastructure that keeps the region in motion.
Castaic maintains a character forged by the interplay of open space and the pragmatic demands of contemporary life. Residents often seek the quiet elevation of the Warm Springs Necktie Trail, where the vista encompasses the sprawling, sun-scorched plains that stretch toward the horizon. While the region is largely defined by its quiet, functional rhythm, the occasional public event at the local park draws the neighborhood together under the wide, unclouded sky. The light here has a sharp, clarifying quality, particularly at dusk when the glare of the day fades into a soft, amber glow. No singular figure looms larger than the landscape itself, as the daily lives of those in Castaic are shaped more by the terrain and the shifting winds of the canyon than by the reach of fame.

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.
