The largest national park in the lower 48, Death Valley National Park is a place of extremes. The valley is 156 miles long, running between the Panamint and Amargosa mountain ranges. It is a unique and challenging hiking destination, and has few marked roads or trails. Summer hikers be warned: in July, the average temperature is as high as 116˚F. The park’s lowest point is Badwater Basin, which lies 282 feet below sea level. But a mere 15 miles away is the 11,049 foot Telescope Peak. Racetrack Playa is another notable feature of the park. This barren lake bed is completely flat.
