Snow tubing is fun. There are some places that you buy a lift/rope ticket, they hand you a tube, and you’re off. Getting back up the hills via tow rope is always an interesting experience – especially if it’s one of the places where you have to hold the rope and ride versus latching on.
Sledding is vastly underrated. I’m not talking about sledding in your backyard with the kids, but heading out into the country to some real hills (think bluffs of SE MN) that are too steep to farm. We used to do this 2 weekends a Winter. We’d get a tractor to the top of the hill early in the year and back it down the hill with the bucket creating a nice smooth “course” with some small edges to keep your sleds or tubes from ending stuck in deep fluffy powder. Light a fire at the bottom or top, mix in a small grill and plenty of beverages and you’re set for a full day of fun.
Winter UTV riding can be fun, especially with the setups people have nowadays with heaters and enclose cabs. There are a few chains of lakes in Northern WI where people essentially cruise from resort bar to resort bar as they would in the summer…but on their UTVs. In some places they take the ice if conditions allow or otherwise the roads.
Choose a weekend where the road conditions seem favorable and get a group to tour some distilleries and breweries. Be sure to designate a driver ahead of time, and just see where you end up for the day. Some of these impromptu adventures have made for memorable day trips with friends.
