A stark wooden guard tower alerts drivers to one of US history's darkest chapters, which unfolded on a barren, windy sweep of land some 5 miles south of Independence. Little remains of the infamous war concentration camp, a dusty square mile where more than 10,000 people of Japanese ancestry were corralled during WWII. The camp’s lone remaining building, the former high-school auditorium, houses a superb interpretive center. A visit is one of California's historical highlights and should not be missed.

A self-guided 3.2-mile driving tour around the grounds usually includes a recreated mess hall and barracks, vestiges of buildings and gardens, and the haunting camp cemetery. Sites are all accessible by foot or an auto road tour.
