This fascinatingly beautiful 1,235-square-mile Southeastern California park is named for the Yucca brevifolia tree that makes it so unique. Joshua Tree National Park established in 1994 is where the high Mojave Desert and low Colorado Desert meet and contains rock formations that are more than 100 million years old. It has nine campgrounds, three visitor's centers and about a dozen trails. Popular park attractions are Giant Marbles, Hall of Horrors, Old Woman Rock, Cow Camp, Barker Dam, Desert Queen Mine, Ryan House and Lost Horse Well, Keys Desert Queen Ranch and Wall Street Mill. The park's especially dark night sky makes it an ideal location for stargazing.
