Santa Clarita sits in a broad valley about 35 miles north of downtown Los Angeles, just over the San Gabriel Mountains via the I-5 Newhall Pass. It's a sprawling, suburban city — one of the largest in California by land area — but it earns its place on the map with two things that draw visitors from across Southern California: Six Flags Magic Mountain, home to more roller coasters than any other park on earth, and a quieter, more surprising history rooted in gold mining and silent-era Hollywood.
The valley's old town core is Newhall, where the William S. Hart estate preserves the ranch and mansion of the great cowboy actor, complete with a small bison herd on the grounds. Placerita Canyon, a few miles east, is where California's first gold was discovered in 1842 — a full six years before Sutter's Mill. Neither site draws crowds, which is part of the appeal. East of the city, the wind-carved sandstone slabs of Vasquez Rocks have been the backdrop for hundreds of westerns and the original Star Trek; in San Francisquito Canyon to the north, the broken concrete of the St. Francis Dam records one of the worst civil engineering failures in American history.
For most visitors, Santa Clarita is a day trip from Los Angeles. Come for Six Flags, stay to walk the Hart estate at dusk when the bison are active. It makes for an odd but satisfying day.
