"Zzyzx (AKA Camp Soda and Soda Springs) is located at the end of Zzyzx Road, a 4.5-mile-long rural road off Interstate 15, in San Bernadino County, California. Zzyzx and Soda Springs are both open to the public and offer a variety of outdoor activities, such as hiking trails, roadside attractions, toilets (always a plus!), and a cute, scenic picnic area. The actual history of the area goes back all the way to prehistoric times, when nomadic tribes would gravitate to the natural spring, and use the site as a quarry to create arrowheads. When you visit keep a keen eye out for rock art. Since 1976, California State University has managed the land and have built a great Desert Studies Center on site." -Roadtrippers
