Straddling the borders of California and Nevada, Death Valley National Park has a color palette nothing short of otherworldly. 86 meters below sea level, it is one of the hottest places in the world. If you are driving from Los Angeles, follow the long straight road through the Mojave Desert to get to the sand dunes at Mesquite Flats. You'll definitely want to stop along the journey to take it all in. You'll either feel like you've landed in heaven or in Mars!
