Santee Camping
Camping in grass and dirt patches with some large trees for shade. Warmer temperatures in the summer make you wish you were farther northeast in the mountains... but his area in east county SD is nice location for hiking Iron mountain or Potato chip rock.
Like the ther their review mentions, it is more of an RV zone from time to time, and it is a more rural area where the folks come out with fireworks during the holidays... but you can find some privacy around the six lakes
