Glacial River Trail

The Glacial River Trail traverses farmland, prairie, wetlands, and forests in southeastern Wisconsin. Extending from Janesville to Jefferson, much of the route runs next to Wisconsin State Highway 26. It meanders by the Rock River, crossing it in Fort Atkinson. The paved trail is 24.1 miles and passes through Milton, Koshkonong, and Fort Atkinson.

While sections of the trail pass through forests, much of it follows a four-lane highway.

There are several attractions to note along the trail. North of Koshkonong, trail-goers find a quaint covered bridge. Further north, a spur trail leads west to Koshkonong Mounds Road. This side trip takes cyclists to Indian Mounds Park. It features 11 Native American effigy mounds and an ancient Indian trail. Throughout much of Fort Atkinson, beautiful sculptures line the Glacial River Trail.

Several trailheads are located along the route, but none are found at the northern and southern terminal points. Trail parking lots are located at Koshkonong, Groeler Road Boat Ramp, and in Fort Atkinson at Farmco Lane. Lions Park and Klement Park in Fort Atkinson are located on the trail and also have parking available. Another parking lot is found at the Jefferson County Mountain Bike Park on County Road W.

The trail meets the Rock River along its route.

There are plans for extending the Glacial River Trail north, to join the Wild Goose State Trail near Clyman. Three completed sections of paved trail are found along Wisconsin State Highway 26 between Jefferson and Clyman. One section is near the trail’s intersection with the Glacial Drumlin State Trail at Jefferson Junction. Another segment is north of Johnson Creek. A third section is runs from Watertown toward Clyman. These three completed sections make up about 7 of the 28 miles from Jefferson to Clyman. When completed, the Glacial River Trail will run nearly 55 miles through Rock, Jefferson, and Dodge Counties, and connect with the Wild Goose and Glacial Drumlin State Trails.

There is no fee to use the Glacial River Trail. Obey all posted signs and practice appropriate bicycle etiquette. Dogs are allowed on the trail, and must be leashed. Overall, the trail is a relaxing and enjoyable trip through open areas and forests.
