Need to Know
Check the Kettle Moraine Trail Line - South for trail conditions (262 594-6202).
Shared trail with mountain bikers and during peak times, Rangers will ask hikers to go to other nearby trails.
This is another great run in the South Kettle Moraine Forest. The trail was designed for mountain biking, so there are a lot of weird turns and unnecessary switchbacks to cover compared to the nearby John Muir trails. The trail is mainly singletrack, except for a few rocky and rooty sections and big ridges with tough climbs along the southern part of the loop. Look for the many glacial erratics right off the trail, along with the usual glacial features seen in this area. The trail climbs, traverses and descends these ancient glacial ridges, which makes it fairly challenging. There are some fun, windy descents, as well as a nice scenic overlook of Spring Lake and Palmyra at the west side of the loop where the Green Loop meets the Muir/Carlin Connector Trail.
