Death Valley is the hottest, driest, and lowest national park. It is also the largest park in the contiguous United States with dunes, salt flats, mountains, badlands, canyons, and valleys sprawling over 3.4 million acres. Death Valley is famous for Badwater Basin, the lowest point in the US, at 282 ft below sea level. We camped nearby in aptly named Furnace Creek at an elevation of 190 ft below sea level.
