16. Death Valley Racetrack Playa

It's one of the hottest, driest, places in the world and over 90 percent of this national park is designated wilderness. With a great network of backcountry roads and a local jeep rental company, we get off the beaten path to discover Death Valley's hidden secrets. From the mysterious moving rocks to long forgotten ghost towns and a hike around the bizarre Ubehebe Crater, there are endless possibilities to explore this extreme landscape well beyond where the pavement ends.
