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!
We started in downtown Menomonee Falls. We parked in Mill Pond Park on Roosevelt, then rode our bike over to Water Street where the trail begins. That probably wasn’t the best place to start because we had to cross the two scary intersections; Highway 175 with a crossing light and Main street on a long diagonal with no crossing light.
This is a very nice trail with wooded areas that pass through residential areas and some business areas. The northern end has some fields. On the southern end you have to stop to cross at a lot of roads all the way to and through Sussex. Luckily the car drivers are very courteous and stop to let you cross. It was nice to see kids of all ages on the trail. It’s pretty flat until you get past the Fireman’s Park soccer fields in Merton. Then you have some pretty steep hills.
Beautiful shaded part of the trail in Fond du lac county. Four tree areas blocking path southwest of Oakfield.
Good easy trail. Started in New Glarus and went foe about 2 miles.
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
We prefer paved trails and the Great Sauk Trail is among the best we've ridden! Ride it again last Saturday and the trail has been extended on the NE end since last time we rode it. Take a detour and check out Thoelke Cemetery for a bit of history; sites dating back just after WI became a state in 1848! Great eats at Gym Bar in Sauk and outstanding mojitos on the deck at Queues Bar right along the river just south of the Hwy 60 bridge in Prairie du Sac!
Sept. 27, 2025 / Incredibly wonderful temps inspired us to make the 1 1/4 hr. Drive to Sauk City for one of our favorite trails. We started at the southern end and rode the length to the trail head near Devils Lake State park. While the trail would really be enhanced if it would end within the state park, my wife and I find it a wonderful ride. Interesting mile markers, lots of areas with benches for rest stops, beautiful scenery along the way; and the trail has been always maintained to perfection.
We rode the trail from Eden to a couple of miles past Campbellsport on a beautiful late September day and thought it was one of the best we've ridden. The trail was very well maintained, and the surface was solid despite recent rain. Although it's described as level, we did notice some definite up- and downhill sections with our heavy old tandem. Another note: contrary to the TrailLink map, there is a very nice restroom in the Eden Community Park, which is helpful if you need to change back into street clothes after your ride.
