You don't find many places that are as open as Simpson Springs.  The camp features pit toilets that at the campsite were very clean (not as much at the ones down by the main road - but not terrible).  Seasonally water is available, it wasn't as of 4/16/23.  Each site has a fire pit and picnic table.  If you like the open desert, this place is gorgeous.  Not far from topaz mines and the geode beds.  You can occasionally see the Army practicing out in the distance which is pretty cool as well.  We use Xfinity Mobile which is on the Verizon network and had no cell service at the campground.  You can get cell service closer to Dugway (north of the campground).
