Emma Carlin Trails Professional Review and Guide
"The Emma Carlin Trails can easily be described as the little brother to the nearby John Muir trails, a little smaller and less established, and hanging on by a shirttail in the form of a 5.5-mile-long connector trail. This small cluster is another in a series of well-marked and maintained Kettle Moraine Forest Mountain Bike Trails. In comparison with John Muir, this set is a little less traveled and the distances are a bit easier to handle for riders not yet ready for 10 miles of technical challenges and climbing.
There are three loops here: a 4-mile outer loop designated as Green, a 2.4-mile Orange Loop, and a 2-mile Red Loop. The 5.5-mile connector trail is a two-way path covering some of the most exciting terrain in all of Wisconsin, with switchbacks, rocky descents, and wide-open singletrack. In the fall, the hardwoods explode into a panorama of autumn colors, while the pines maintain their contrasting green hue. Elevation Change: The terrain is choppy and seldom level. The majority of the climbs are 20 to 30 feet, but several are in the 60+ range. Two in particular are found at the tail end of the connector to John Muir, both at insanely steep pitches. There are several on the south side of the Emma Carlin Loops."
