You don't need a visa to go to Siberia. At least, the one in California. You will need to use some mapping skills and your imagination though, to get there.

Siberia was originally founded as a water stop and rail siding for the Sante Fe Railroad, which later also became a motorist stop for travelers along Route 66. It was located between Bagdad and Ludlow and must have had some years of minor prosperity. Cafes and tourist camps operated here during the 1930s and 1940s, but things never quite took off.
