The Serrano, including the Alliklik, Kitanemuk, and Vanyume, lived in a large area to the east and north of Los Angeles, California, in the San Bernardino Range, Tehachapi Mountains, and environs. They spoke Serran languages of the Uto-Aztecan stock. The one hundred or so Serrano descendants live mostly on the Morongo and San Manuel reservations in California.
