About an hour away from Los Angeles is Riverside, located in Riverside County. This city is a must-visit for history lovers. Notably, this underrated Southern California destination is home to the iconic Mission Inn, a luxurious hotel dating back to 1876 famed for its clientele like President Theodore Roosevelt. Then there’s the California Citrus State Historic Park, an open-air museum founded in 1993. Thanks to Southern California’s Mediterranean climate, Riverside is known for producing varieties of oranges and was a key location in the state’s early citrus industry, established in the 19th century.
