This is one state park to see... - There are lots of plants and animals to see. During our last trip to Ha Ha Tonka we saw; deer, fox, badger, raccoon, squirrel, rabbit and many species of birds. The ruins are interesting, the mechanics of the water tower and pump are very interesting as is the the spring below. On a HOT day the spring is the place to ESCAPE to a cool, natural ~58 degrees Fahrenheit!
