Book excerpt: Every day, thousands of Southern California residents see the California Channel Islands on the horizon, yet few can name all eight. Santa Catalina Island, third largest, is by far the best known. It is the only island with a city, Avalon, where dozens of hotels, shops, and restaurants await visitors year-round. Three of the islands are owned by the US Navy: San Clemente, San Nicolas, and San Miguel. San Clemente and San Nicolas Islands are used for military training, naval weapons development, and missile testing; thus access is restricted. Five islands fall within the boundaries of Channel Islands National Park: San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara Islands. Close to the mainland and yet worlds apart, scenic day trips and primitive camping opportunities are available on all five park islands. With neither stores nor modern conveniences, a trip to Channel Islands National Park is a step back in time.
