Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Friday, February 20, 2015:


The forest has received just a dusting of new snow since February 3rd. The skate lanes at Zillmer were touched up Thursday morning, February 19th, and staff do not expect to do any further grooming until Monday Feb 23rd, at the earliest. Conditions are fair to good, but expect some debris on the trails. Conditions are similar at Greenbush, but be cautious for icy conditions. Note the Greenbush and Zillmer ski trails are now closed to hikers and pets, as grooming has begun. Snowshoers and hikers are welcome on any trail in the forest except the groomed ski trails. The snowmobile trails remain closed.

Remember, a state trail pass is required for equestrians, mountain-bike riders and Zillmer trail skiers ages 16 and older. No trail pass is required for hiking or snowmobiling. A vehicle admission sticker is required in all fee use areas.

Cold temperatures have settled in, but wildlife are still active looking for food. Every fresh snow brings new opportunity to see who's been wandering through the forest – look for tracks of deer, turkeys and rabbits, the tunnels of mice & voles, maybe even a scuffle site where a hawk has caught it's prey. Now is also the time of year to look for antlers that the deer have begun to shed. The white backdrop and lack of leaves create great opportunities to view the glacial kames, kettles and eskers throughout the forest.


The lakes have been rapidly forming ice due to the recent colder temperatures, and fisherman have been out on the forest lakes. Be advised that the DNR does not monitor ice conditions, and does not consider any ice to be 100% safe. Please use caution when venturing out over the water. All boat launches in the forest are open. When we get enough snowfall, all launches except Forest and Butler lakes will be plowed. Some areas will require a state park sticker. Please see our lakes page for more information.


All deer hunting has ended for the season. However, many small game seasons remain in progress through February. About 95% of the forest is open to hunting within established open seasons (see map).

The Zillmer Trail area remains bow hunting only for small game, while the Tamarack and Summit trails and both campgrounds are entirely within refuges and not open to hunting at any time.
