Death Valley National Park is more than just the lowest, hottest point in the United States. Although Badwater, which is below sea level, is one of the most interesting parts of the park, be sure to spend several days here. Come to Badwater at noon in the middle of the summer if you are crazy. For the rest of us, try very early in the morning, or in winter. My GPS recorded my elevation with a negative number, which I thought was interesting enough to use as a waypoint. Another must-see part of this California desert park is the sand dunes. If you have ever wanted a Sahara experience without the overseas trip, bring a compass, lots of water, a GPS, and a very good map, so you can find your car again after your wander through the dunes. Two steps forward and one step backwards. There are also some several scenic drives in this park, and some nice boardwalks. The Panamint mountains tower over the valley, for a completely different experience. These mountains are difficult to access and do not get as much tourist visitation as the more developed low desert areas.
