A must stop site if you’re driving Highway 50. Don’t worry about the access road. It is paved and I took the first pic from the car park near the entrance. I’d visited it a few years ago when it was just a sand dune in the middle of nowhere. It’s now been turned into a recreational area and is used by various off road vehicles. There is a charge to enter but if you talk nicely to the staff on the entrance they will give you a free 1 hour car pass if you’re just sight seeing for under an hour. When you first see it from Highway 50 you just can not appreciate just how big the sand dune actually is. Well worth a visit if you’re passing.
Be VERY careful when driving in and out. The access road is in perfect condition but the drainage channels across the road are nigh on impossible to see and they will trash the underside of your car if you hit them above the posted 5mph speed limit.
