Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Wednesday, February 10, 2016:


More winter-like temperatures have returned, and the forest received up to 2 inches of new snow Tuesday night and Wednesday. The Zillmer and Greenbush ski trails were groomed and retracked on Tuesday. The Zillmer skate lanes rated very good, while the classical tracks are good with some thin and icy spots. The Greenbush trails got a bit more snow and are rated very good to excellent. Groomers will attempt to touch up both trail systems again before the weekend.  For the latest conditions, please check the [exit DNR] website.

Remember, a state trail pass is required for all skiers ages 16 and older for both the Zillmer and Greenbush ski trails (new this year). A vehicle admission sticker is required in all fee use areas.

Snowshoers are welcome on any trail that is not a designated ski trail.

Events and programs

2016 Winter into Spring Nature Program Schedule [PDF]

See the DNR Events Calendar for a list of all events at Kettle Moraine North and other state park properties.


Beginning with the 2015-2016 snow season, all snowmobiles operating on a Wisconsin snowmobile trail or corridor must display a valid snowmobile trail pass whether registered in Wisconsin or another state. For more information, see Snowmobiling in Wisconsin.

The opening and closing of snowmobile trails is at the discretion of each county, including the snowmobile trails which cross DNR lands. Whenever possible, the opening and closing of snowmobile trails is done on a county-wide basis, however localized conditions may require localized trail opening and closing. It is the responsibility of the county to provide notification about the status of snowmobile trails. The Travel Wisconsin Snow Conditions Report [exit DNR], and local club and county snowmobile web pages [exit DNR] and telephone hotlines will provide the most current information.


Mauthe Lake Campground. The 100-400 loop sites are available first-come, first-served through winter; however, only the 100 loop will be plowed. Campers should follow the instructions at the entrance station bulletin board (cash or check payments only). All showers and flush toilets have been shut down, but drinking water is available all winter from the spigot behind the entrance station.

Long Lake Campground has closed for the season. The campground will reopen and sites are reservable beginning April 29, 2016.

Greenbush Group Camp is closed for the season and will re-open April 29, 2016.

New Prospect Horse Camp is closed for the season and will re-open April 29, 2016

Backpack Shelters: Shelters 1-5 on the Ice Age Trail are open and reservable year-round. Shelter 6 on the Zillmer Trail is closed for the winter ski season, but will re-open April 1, 2016. 


The fishing pier and boat boarding dock at Long Lake have been removed and the beach houses at both Mauthe Lake and Long Lake are closed for the season. The boat launches at both locations are open and will be maintained through winter for ice fishing.

Please remember that ice conditions can change from place to place and from day to day. Park staff do not monitor ice conditions, thickness or safety. You must use your own judgment in deciding about venturing onto any ice. Tips on staying safe on ice.

Please see our lakes page for more information on fishing, boating and other recreational opportunities.


About 95 percent of the forest is open to hunting during established open seasons while the Tamarack & Summit trails and both campgrounds are entirely within refuges and not open to hunting at any time. Likewise, no hunting is allowed within 100 yards of any other campground, parking lot, shelter or Parnell Tower. Hunting map [PDF].
