Moon Lake is a hidden gem in the high Uinta Mountains.  We were in group site B.  Lots of places to put tents and campers.  Walking path to the lake.  Lots of hiking trails.  One must bring item, is a camping canopy to put over the tables.  It helps with keeping the sun and rain away from a good time.  There is also a regular campground.  I would suggest Upper Loop because there is more shade.
