We traveled down on Saturday from Denver to Great Sand Dunes and then hit up this convenient spot around 5pm and stayed for one night.  Was extremely well positioned being 15 min from the park and about 5 min down the road from Zapata Falls which is a quick and easy hike.  Upon entering it was really impressed with the layout.  Tons of spaces with ample room between vehicles and you have the choice of being down low where it's more flat vs. up into the hill side a bit.  We probably went about a mile up before picking a spot off the fairly rocky and bumpy road.  The road is actually pretty well maintained and there are spots all over the place which was great.  Most spots looked to come with a fire pit if desired but was rainy for us.  

Overall, would highly recommend getting up into the bushes just for a bit more privacy as well as shelter from some of the wind.  The weather does whip in fairly fast and most locations are pretty exposed so just be prepared to withstand some strong wind but it does come in spurts and won't last forever.  The campsites were great though and offered some fantastic views of the plains as well as up towards the mountains.  We will definitely be coming back due to its location and space!
