A must-do for area bikers the winding, hilly trails at Moraine Hills State Park pass through more than 2,500 acres of quiet kettle-moraine landscape. The park’s entire trail system covers more than ten miles in a series of connected loops that wrap far out around beautiful, rich savannas, open uplands, lakes, prairies, a bog, and riverside wetlands.
The trail system has three major loops: the Leatherleaf Bog Trail, the Lake Defiance Trail, and the McHenry Dam section. The majority of the path is limestone, however, many of the hills are paved to prevent erosion. Much of the trail is one way...so be sure to follow the signs and go the right way. The section that shadows River Road is paved.
