The easily accessible Mesquite Flat Sand Dunes are located at the northern end of the valley floor. These 14sq miles of sand dunes were used for several movies including the Star War series.
I walked to the largest dune called the Star Dune, located about a mile from the parking lot. Unfortunately, because of the easy access there were footprints everywhere :-(. To get pictures of undisturbed dunes we have to hike further into the dunes. I did not have the time and made do with what I had.
