Gravel was so deep it was not possible to ride on it. Only seems realistic for ATV vehicles which we saw plenty of. We needed to reroute our course because we could not ride on this trail.

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.

Attempted this 23 Nov 2019. At least one 6 mile section is still closed from Elroy west, including a bridge.
The tunnels were also closed, making most of the trail impassable.
If not frozen, the surface was a muddy mess.
I'm sure this is a great trail when it's dry and all sections are open.

Rode the SRT from Broadhead to New Glarus on Friday 10/25. Great scenic trail but some maintenance is needed, passed four down trees blocking the trail. Also some holes made by some critters you would not want to hit. Most of the mile markers were gone.

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.

Rode south to north (elroy to camp Douglas) and back on our fat tire e-bikes. Good scenery, lots of bridges, super tunnel , beautiful weather. Yes there are potholes and even with the fatties, some holes were rough. The asphalt should be milled back to crushed gravel imo. However snowmobile tread and use during the breakup season may be why the surfaced was asphaulted.

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.

Plenty of space to park stock trailer in gravel lot on Lake Shore Rd Clinton. Cute little covered bridge in small park with picnic tables was the start of my mule ride. There were trash receptacles, handicap accessible restroom & a wood post hitching rail. Many "sponsored" rest spots with wooden benches, picnic tables & some had roofs along the flat trail. Trail bed is wide, flat & firm as small crushed gravel & grass base. Views of plant/tree farm & rural properties after brief bit of SE side of Clinton. Mileage markers. Several blacktop road crossings. Easy, well-groomed trail. Small gravel lot at east end with trail map on kiosk. For lunch at Boar's Nest Bar ride Hill St (right uphill), stay right on Clinton St, quick Left along west side of the Park 1 block to stop sign Cty X. Ride directly across Cty X then straight across grass to cable picket line.
I-43 runs parallel to trail. Loud traffic but distance kept equines from becoming unnerved 🙂 Met a jogger, a hiker with a leashed dog on trail & 2 bicyclists at covered bridge. All were respectful of equines.

Forestville to Algoma: Peaceful, relaxing ride through rural Wisconsin and the bridge offers a nice spot to stop and enjoy the view for a moment. I would have given this section of the trail 5stars, but the area near the marsh had high water due to the recent rains and the shoulders are softer much more to the middle of the road than expected.
