Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Thursday, July 31, 2014:

Alert: Highway 28 in Kewaskum is closed to all through-traffic until fall. Visitors and campers coming to the forest from the south via Highway 45 should follow the Highway 67 detour, seven miles north of Kewaskum. Please contact the Forest Headquarters or Ice Age Visitor Center if you have any questions or need further direction.


The horse and mountain bike trails are now open for the season; however, muddy stretches still remain.  Riders should refrain from using the trails within 12 hrs of a rain event, to prevent long-term damage.  The north end of the Tamarack Trail is still quite wet and travel is not recommended. The Lake to Lake Bike Trail is has re-opened south of the Headquarters Rd, but portions are still quite wet and muddy. All trails have been mowed at least once this summer. The Bridle, Greenbush and Zillmer trails will be mowed again later this season.

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

Events and programs


All campgrounds are now open for the season.  The entrance stations at Mauthe Lake and Long Lake are open daily 10 a.m.-7 p.m., Fridays until 10:30 p.m.  After 7 p.m. until 11 p.m., campers may self-register on any open for one night only. Self-registration is not allowed from 11 p.m. to 10 a.m.

Greenbush Group Camp is open until November 23.  Reservations are required for this campground.

New Prospect Horse Camp is open and reservable through October 25.  Firewood and trail passes are available from the camp host.  Riders may also self-register for vehicle stickers and trail passes at the campground. 

Backpack Shelters:  Shelters 1-5 on the Ice Age Trail are open and reservable year-round.   Shelter 6 on the Zillmer Trail is also open and reservable from April through November.


The wet spring and summer has made for lush vegetation, but also a healthy mosquito and deer fly population. Temperatures have remained very pleasant and mild this season. The first signs of fall are beginning to show, with cicadas buzzing, blackbirds flocking up and some tinges of orange on the occasional tree. Wild parsnip is in full bloom and hikers are encouraged to become familiar with and avoid this harmful plant.


All boat launches in the forest are open, as are the fishing piers at Long Lake and Mauthe Lake. The road to the Mauthe Lake Boat Launch has re-opened, but high water remains at the loading dock. Launch fees are not required in the forest, but some areas will require a state park sticker. See the Kettle Moraine State Forest - Northern Unit lakes page for more information.

The swimming buoys are in place and beach houses are open at Mauthe and Long Lakes. Beach water tests have indicated good water quality at each of our 3 beaches all summer.

The Henry S. Reuss Ice Age Visitor Center is now open seven days a week.  Weekday hours are 8:30 a.m.-4 p.m. and weekends 9:30 a.m. - 5 p.m.
