I and a beautiful friend of mine got to ride this beautiful scenic ride from fond du lac to rose n dale and back today and we absolutely enjoyed the whole experience, a bit windy but a nice 2:30 hr ride at a leisurely pace. Happy trails to you all!

took it from the park and ride was about a 30 minute walk, great paved path right next to the highway

I've been on every part of the trail, hundreds and even thousands of times in some places, since it was called the 76 trail; and other nearby wild areas that were de facto part of the trail before officially being made so.

On one occasion, this included circumnavigating the county on foot in 1 day; through almost every municipality in the county, mostly on the trail, but briefly off and beyond it into Waukesha county.

Really nice trail to walk or ride bikes. Good place to take your dog for long walks. Many access points. Even has an access point to Miller Park for bikers or trail hikers. Just wish they had a few trash receptacles every mile or so. Maybe then more people would pick up after their pooches.

This paved trail is a short (3 mile) north-south connector between two more prominent east-west rail trails -- the Lake Country Trail and the Glacial Drumlin State Trail. The route in its entirety parallels Cushing Park Road, running for more than a mile along the western edge of Lapham Peak State Park and Evans Prairie, where views of prairie grasses and wildflowers can be enjoyed by passing bikers and hikers. Elevation changes over the gently rolling terrain are easy to negotiate.

I returned on one of those great Midwestern fall days to complete the portion of the Glacial River Trail south of Jefferson. I found the few miles that were in-fact a former railroad. The rest of the trail is in the WI-26 freeway corridor or on rural roads and city streets, but the trail is all paved.
The city of Fort Atkinson is very attractive with trail amenities including public art. I again found that the TrailLink map was a necessity as the signage on the tail is sparse.
My only negative is there is no need to do the on-highway portion south of N Wright Rd unless you want to continue to the connection to the Spring Brook Trail that will take you into Janesville.
For an out and back trip consider places where you can use the parallel old WI-26 for a different landscape view.

The Glacial River Trail in the Rock River valley is untypical for Wisconsin state trails in that it is entirely paved and not a rail-to-trail. It has a great mix of segments in the WI-26 freeway corridor, city streets and rural roads, with some good grades. I did the north part of the trail from Jefferson to the junction with the Wild Goose State Trail. There are no services provided by the trail owner, but the trail is free to use. The signage for the trail-turns is minimal so the Trail-Link map downloaded on your smart phone is a must. I especially enjoyed my ride thru the river towns of Jefferson, Johnson Creek and Watertown, where I took the time to ride around the downtowns. I will come back someday to do the south portion.

Parked at Cottage Grove today and biked out 23 miles and then back to car. It was annoying that we both paid our 5 dollars and then visited the rest room. No toilet paper in mens or women's and both stalls in women's were smeared with feces. Nice surface on trail. Not enough benches. This trail would definitely not qualify as a national rail trail.

I grabbed the trail north of Janesville on my road bike. Crossed the bridge over the highway and did about a mile on the county road before winding through a new housing development and finding the actual trail. It's in great shape, lots of gentle rolling hills and a couple of roundabouts but not a single person anywhere along the trail. I rode to Milton and most of the trail parallels the highway so it's loud on one side but beautiful and agricultural on the other side. I saw hawks and finches and no humans of any kind. It was pretty sweet. I only gave it 4 stars because of the highway driving . Otherwise it's a 5-star paved trail.
