We will be in the area in early October. Can someone please give us an update on the condition. Recommendations on Elroy-Sparta or 400 trails, please and thank you. Happy trails.
Rode from Dodgeville to Barneveld. The trail is pretty rough and feels more like a dirt road than a rail trail. Some sections are fine, but on other sections you really need to pay attention.
Fantastic trail! It’s fully paved and not busy at all. We started at the trail head and biked to Sauk City, then stopped for a coffee before heading back. The weather was perfect. What a great day of biking!
Made up of 2 nice country trails with mostly decent crushed limestone surface separated into 2 parts by highway 23 which is an unsafe, busy, fast highway with a pretty wide gravel shoulder. There are no toilet facilities. Some biting flies if you stop but we didn’t get any ticks.
We first attempted to ride the Ripon to Berlin segment. In Ripon you can park slightly past the start of the trail off Locust where there is a nice parking area and pavilion. We only got about 6 miles or so before we had to stop for a very large downed tree. We could have stopped at Vines and Rushes Winery but it was a little early for us.
At the Berlin side of the trail there was a sign in a grassy area for parking across the street from where the grassy trail begins at Berlin Feed. Didn't look like that end of the trail got much use. It wasn’t worth getting tandem bike out of van to ride just a few miles so didn’t ride that part.
Then we rode our bike from Rosendale to Fond du Lac. We parked along the side of Zamzow (neighborhood) Park on Willow Creek Rd just off North St. We rode the short segment to Hwy 26 and then turned around and rode to Fond du Lac where trail ends on VVV with trail head parking.
Beautiful shaded part of the trail in Fond du lac county. Four tree areas blocking path southwest of Oakfield.
Love this trail but rode today between Riley and Brigham County Park and found the trail to be in extremely rough shape on either side of Mt. Horeb. Lots of ruts, giant holes and loose sand. Slow your roll and pay attention to utility flags and sticks identifying some of the bigger holes. Stay safe!
Beautiful country trail. A lot of tree cover and not very many other people. Worth the ride.
We took this trail from the Wild Goose trail but had no idea we would be on so many roads. As you got closer to Watertown, you are also on the road. We personally try to avoid roads as much as possible so we didn’t like this part. We only went to Watertown from the North so I am not sure what the rest of the trail is like. The actual bike paths are great.
Storm last night, tree across trail at 5.25. I'm contacting dnr now
Closed between CT H TUNNEL ROAD AND HOFF ROAD FOUNTAIN TOWNSHIP WI
