Coming from Vegas, this will be a little out of the way, but if you stay on I-80 east to Rock Springs and head north you can eventually make it to Killpecker Sand Dunes. Went to Yellowstone last summer with my boys and we spent a day at Killpecker on our way to Jackson. Great time at the dunes and the drive to get there is pretty fun as well. Lots of places to open it up. And I believe some of the mountain passes that you might explore are off the highway that comes north out of Rock Springs so you might be headed that direction anyway.
