Death Valley National Park can best be described in superlatives: it is the hottest and driest park in the U.S. and is home to the lowest point in North America. Its extreme temperatures make it best visited in the winter, when snow caps the mountains and the low light gives the desert a golden hue. Spring brings over 1000 species of plants to bloom. The park's many trails take hikers through salt flats, soft dunes, gorgeous canyons, natural bridges and vibrantly colored badlands.
