Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Monday, March 16, 2015:


Warm, spring temperatures have left very few traces of snow in the forest. The ski season, by all appearances, is done for the season. Hikers may now use the Greenbush and Zillmer ski trails, but should be alert for mud and remnant ice on some stretches. Due to wet conditions, the mountain bike and horse trails are now closed, to allow time for the trails to dry and stabilize and to prevent long-term damage.

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.

Events and programs

Help give the Kettle Moraine Scenic Drive a spring cleaning! Join us for a morning of camaraderie and litter pickup on Saturday, April 25th from 8:30 a.m. - 12 a.m. Garbage bags and refreshments are provided, but we recommend bringing your own gloves. Youth and other groups are encouraged to participate by registering with the forest headquarters: 262-626-2116.


Mauthe Lake Campground - The 100-400 campsites are open for first-come, first-served camping through April 9th, and reservable sites begin April 10th. The entrance station is closed, but self-registration is allowed on available campsites by following the instructions at the entrance station bulletin board. Flush toilets and showers will remain closed until all threat of frost has passed – usually late April. Drinking water is available year-round behind the entrance station. Firewood may be purchased from any local vendor within 10 miles, including Zahn's Trading Post (New Prospect) and Dins Mini Mart (Dundee).

Long Lake Campground - has closed for the season and will reopen May 1st, 2015. Reservations are now being accepted with ReserveAmerica.

Greenbush Group Camp - is closed for the season and will reopen May 1st 2015. Reservations are required in this campground

New Prospect Horse Camp is closed for the season and will reopen May 1st 2015.

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, but is reservable from April through November.


Spring has made an appearance in the forest, with snow hanging on only in the most sheltered locations. It won't be long before the first spring birds start arriving and the frogs begin their mating calls.


Most lakes are still ice-covered, but melting fast. Fisherman should be very cautious of thin spots as well as slippery conditions. Please see our lakes page for more information.


Most hunting seasons are complete, until the Spring Turkey season begins on April 15th. About 95% 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.
