Horse Creek is a great site for horse camping. Only two sites are for non-stock campers. The camp has no water or any hook ups but the corrals are pretty good except they can get muddy if manure is not carefully picked out. 

The horse water trough is a short walk away from camp but does not have potable water. If users are not careful it can drain or not be usable so bring horse water. 

The trails are wonderful!! But hilly so make sure your horse is fit or you are willing to take it easy. Many of the original overlooks are starting to be grown in but the forest is amazing!
