Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Thursday, Feb. 23, 2017:


The recent warm spell has removed the frost from the ground, and almost all traces of snow off the Forest trails.  With a forecast well above freezing into the first week of March, we are now allowing hikers and pets on the Zillmer and Greenbush ski trails.  However, the mountain bike and horse trails remain closed, until they can dry sufficiently to prevent long-term damage from rutting. 

Visitors can check the website [exit DNR] for the latest ski trail conditions.

Please remember, hikers, snowshoers and pets are prohibited from the Greenbush and Zillmer cross-country ski trails.

Skiers are reminded that a state trail pass is required for all skiers ages 16 and older. A vehicle admission sticker is required in all fee use areas.

Snowmobile trails in the forest are closed.

Snowshoeing: Snowshoers are welcome anywhere in the forest except for the groomed ski trails.

Events and programs

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


Mauthe Lake campground is open for first-come, first-served camping through winter, although only the 100s loop will be plowed. All water has been shut down, except for a drinking water spigot behind the entrance station. All campers must self-register for sites by following the instructions at the entrance bulletin board. Reservations are now being accepted for the 2017 camping season, which begins April 7, 2017. Firewood is available from an automatic dispenser, cash sales only.

Long Lake campground is closed for the season, and the beach houses are also closed. The day-use areas and boat launch will remain open through winter. Long Lake campground is taking reservations for next season, and will re open April 28, 2017.

New Prospect Horse Camp is closed for the season. Reservations are being accepted for the 2017 camping season, which begins April 28, 2017.

Backpack Shelter 6 at Zillmer is now closed for the season, and will reopen April 1, 2017.

Other Ice Age Trail Backpack Shelters remain open and reservable year-round. See the Backpack Shelter Guide [PDF] for information, water sources and reservations.

A reminder that open-land camping is not allowed in the Kettle Moraine State Forest. All overnight visitors must be registered and stay on a campsite.


After a long stretch of warm weather, travel on any remaining ice is not recommended.  Anglers and boaters will notice recent work done to the Lake Seven, Auburn and Long Lake boat boarding docks, and the Mauthe Lake fishing pier.  Contractors were able to beat the weather and complete repairs on these structures, and they are ready to go for the new season.

Tips on staying safe on ice.

The Long Lake fishing pier and boat boarding dock have been removed for the season. The boat launch will be open and plowed through winter.

The Mauthe Lake fishing pier will have further improvements made through the winter of 2016-2017, as will the boarding docks at Auburn Lake and Lake Seven.

Please see our lakes page for more information on fishing opportunities. The DNR does not monitor ice conditions. Always use caution when venturing out onto the ice.


All gun deer seasons have closed, and firearms are again prohibited in Zillmer Trail area. Squirrel season closes Jan. 31, and rabbit season closes Feb. 28. Visitors might consider wearing brightly-colored clothing when venturing outside of the closed hunting areas. A limited number of blaze orange vests are available to borrow at the Ice Age Visitor Center.

About 95 percent of the forest is open to hunting during established open seasons while the Tamarack and 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].
