[I visited in 2014 and these pictures are from that time.]
Natural Bridge State park is a small park between Sauk City and Baraboo. It is home to Wisconsin’s largest natural arch. I stopped there to take the short hike to see the arch and find a geocache. Archeologists have found proof of humans being here thousands of years ago. If you are in the area it is worth a stop and short hike.
You can find out more at the DNR and Wikipedia.
