This place is beautiful, but you will very very easily get stuck in sand on your way there (two ways in, both ways have sandy stretches of road that you need to gun and basically risk your life in order to get across, assuming you don't have an off-road friendly vehicle, which you will just have to gun a little less).
Got stuck in the sand for 2 hours until some very kind locals came around the bend and helped us out of it. Sunburns, stress, and delayed schedules all around.
Tldr: Beautiful, but don't go unless you have an off-road vehicle and stuntman skills. If you don't nail it and get stuck in the sand, you will likely be stuck with no service and no one to help you out for at least a couple hours.
Special note! This place still exists, it's just 10 miles or so north, but still on the 160! It's a cool place, exactly what is advertised. I would drop by if you want to see it but not go out of your way if you don't. Watch out for every inch of broken glass smashed everywhere!
