Death Valley is not far from Las Vegas. It's 200 kilometers away. It's a good one-day tourist destination from Las Vegas. Except for winter, other seasons are really honorable for its Death Valley. It's going to kill people. Death Valley is the largest national park in the United States, but because it is so hot most of the time that birds fall, it is totally unable to get out of the car and hike. If winter comes, have a good time. This is the tenderest time in Death Valley.
