Empty campground, all the spots were in the sun. No stalls, only hitching posts which were also in the sun. There is no water, not one spout. No sinks in the bathroom so you can’t even fill up buckets of water in the sink. If you bring your own water and maybe a pen to put your horses up in the shade then this campground would be nice, the trail head is right in the campground.
Apparently Indiana does not require you to have a water source to name yourself a campground so beware, Harden Horse Camp has water but owner is very unhelpful and will turn you away (even if the camp is empty).
