Like the Eagles 1972 hit song, this well-established trail was both peaceful and easy. I biked from Oshkosh to Hortonville and back. The trail was mostly nestled under a canopy of trees. The sides of the trail were mowed and I did very little tree-branch ducking. For the most part, the trail surface was solid and bone dry. Beware of the section next to the mountain of sand in Clayton. Some of the sand has drifted onto the trail causing slippery conditions. The loop around the Fox River Inlet in Oshkosh was a nice change of pace. On the east side of the Fox River by Hwy 21 is the Fox River Brewing Company. They have a large outdoor dining area that includes a beach house and tiki bar!
This trail is NOT for biking—the surface is largely sand and full of ruts and where there is “gravel” it is more like large rocks that cannot easily be ridden on. We will not ride this trail again. It seems to be for ATV’s and not bikers, unfortunately.
I read reviews from April about trees down this is June I rode from Amherst to Scandinavia didn’t make it because trees are still down. Who is supposed to remove down trees on the trails?
it’s a nice trail to bad it’s not being cleaned up.
from Medina to Allenville 05/19/26 there’s a section between county II and county T that’s very muddy especially by the gravel pit it’s always muddy and from Allenville to Oshkosh it’s a better trail
Due to recent storms (ice and heavy rains) the trail is blocked. Biking would is impossible. The first 3 miles of trail from Scandinavia toward Amherst Jct. had at least 20 large trees down across the trail. The locals said the trail from Scandinavia toward Manawa was in a similar condition. The trail winds through beautiful woodland. Hopefully some groups with chain saws and ATV’s can help with cleanup and clearing the trail.

I rode a recumbent trike from Howard to Pulaski. The trail was in good condition and a fairly smooth ride.
The trail is mostly beautiful. Almost all crushed gravel, which we didn’t expect. In some parts the gravel is thick and loose. The only asphalt is on county roads. the concrete, as expected, was on sidewalks in town. The boardwalks were fun but be careful if you are riding on 3 wheels. If I hadn’t just rode the Heart of Vilas and the Root River State Trails, which are as close to perfect as you can get in this region, I would’ve given the Green Circle a 5 star review.
Trail from Wittenberg to Birnamwood is grass covered crushed limestone. They do cut the grass, but not particularly bike friendly.
We’ve done this trail twice and really enjoy it. Was attending a conference in SP and decided to bring bikes along. Weather was perfect for riding so we took advantage and rode this trail. It was wonderful. Love the variety of ‘environments’ you bike through, especially Schmeekle Reserve. The train is well maintained. Only delay was waiting on a train for 45 minutes!!
