My experience was everything I expected; solitude, stargazing, sustainability, and gorgeous views.  I believe November is the perfect time to camp here.  Lots of space to enjoy some peace and solitude.  Camp hosts' were terrific. They were always willing to share their knowledge of solar power and organic sustainability.  This ranch is miles off the main road with the approach road a bit bumpy.  There are lots of dips and loose soil.  A four-wheeled vehicle would fit nicely.  The cost is very reasonable and you must be prepared to dry camp. Bring a full supply of essentials though, the nearest store is miles away.  Big Bend National Park is only 35 minutes to the south.  Older children will love this camp site too.
