Nice hike along the yellow (outer loop).
A very well groomed and maintained trail. Too well for my tastes. Not much of a challenge.
Great changes of scenery throughout the trails. Mosquitos and Flys were starting to get bad when I went on July 5th 2014.
Would recommend this trail for a family hike.
This is a pretty good hiking trail for this area. The Yellow trail is a 5.2 mile loop but can be extended by a few extra miles by combining some of the other loops and trails at this location. The trial surface varies from packed dirt , moss , mowed grass and pine needles. A few areas in the trail have some small rocks sticking up in places. As with most of Wisconsin, depending on the time of year could be mosquito hell. Spring, early summer and fall are nice and mild. Notes that there are a few low points in the trail that can become a bit boggy or wet in the spring. You can park at either the ice age center lot or the sothern lot.
