The park address is 2866 Sauk Trail Road, Kewanee, IL. Sauk Trail Road is off of IL-78, 5.5 miles north of Kewanee or 5.2 miles south of Annawan. The road circles around Johnson Lake, providing access to trails, picnic sites, camping, the boat launch, and the historic Ryan's Round Barn. These locations all have parking areas associated with them, which are not shown on the map.
Johnson-Sauk Trail State Recreation Area has 3.7 miles of trails, ranging from one-quarter mile to 1 mile in length, from easy to moderate, and taking hikers along the lake or through land ranging from rolling prairie to pine plantations and bottomland hardwood forests. If additional miles are desired, the trails have been designed to connect via the loop road, so hikers can link one to another, to make a longer loop around Johnson Lake.
Bicycles may ride along the park's paved road, which is a 3.2-mile loop.
Johnson-Sauk Trail is an all-season park, with summer hiking trails doubling as trails for 3 miles of cross-country skiing. Ski trail maps are available at the park.
