Primitive Camping is authorized 100ft off the trail with a pass that you fill out online. The website is very confusing though. I seen another hiker doing primitive camping so I stayed the night. Recommend protection since Wisconsin is known to have bears and other predators. The trail was good with a few good high point views. There is an additional 1.5 mile trail not listed here, but it does add more mileage, totally approx 9 miles. I had fun.
