History

Castaic Junction was the official southern end of the Ridge Route. The name dates to 1887, before highways were built, when a railroad siding was set up at the junction.
The community had an Art Deco−Moderne style train depot, serving the railroad line that ran along the Santa Clara River between Saugus and Piru. The depot was demolished around 1990.
Just beyond the north end of the Magic Mountain parking lot is the site of the adobe ranch house for the historic Rancho San Francisco, a Mexican land grant that encompassed the Santa Clarita Valley from Piru to Canyon Country.
According to local legend, icon James Dean ate his last meal at the Tip's Restaurant formerly at the crossroads of Highway 126 and The Old Road before he drove on north.
