Encircling the city of Stevens Point, this trail meanders along the scenic Wisconsin and Plover rivers, recalling the history of the lumber-making and pioneer settlements of the area, while connecting secluded natural and wildlife areas, the Schmeeckle Reserve and many city parks. The trail, including all spurs, is 31 miles long and features river scenery, forests, wetlands, prairies, boardwalks and quiet neighborhoods. A one-way spur on Hoover Road south in Plover is four miles and connects to the Tomorrow River State Trail.

The Green Circle is managed locally by the Green Circle Board of the Community Foundation of Portage County and is a cooperative effort among communities, private land owners, individuals and local governments. It is thought to be the only trail system in the country to circle an entire community.
