Spring Valley Ranch Resort, Lake Hughes. Postcard 1950s. The consensus estimate on the vehicle is a 1952 or 1953 Chevrolet. (Per Darryl Manzer, the spotlight was an "extra" that wasn't available after 1953.)

Back of postcard says the resort featured "spring-fed lakes stocked with rainbow trout" and "cool clean campgrounds."

As for directions, it says: "Highway 99 to Castaic - 23 Mi. North on Elizabeth Lake Canyon Road."

We're short on information about the ranch, although a news item from the Bakersfield Californian of July 29, 1954 (courtesy of Lauren Parker) gives us the name Harry Petti:

Saddle Club Wins Prize in Parade

They were guests of Mr. Mrs. [sic] Harry Petti at Spring Valley Ranch, and attended the dance Saturday evening at Sportsman Lodge.
