Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Thursday, July 3, 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 closed south of the Headquarters Rd to Mauthe Lake, due to flooding. The loop hiking trails and the entire bridle trail have been mowed and crews will start on the Ice Age Trail next week.

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 10am-7pm, Fridays until 10:30pm.  After 7pm until 11pm, 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.


Goslings, turkey poults and deer fawns have been spotted regularly and are getting big. The wet spring has made for lush vegetation, but also a healthy mosquito population. Deer flies are not yet as bothersome as previous years and temperatures have been very pleasant and mild. Wild parsnip is starting to bloom and hikers are encouraged to become familiar with and avoid this harmful plant.


All boat launches in the forest are now open and the fishing piers at Long Lake and Mauthe Lake are ready for action. The road to the Mauthe Lake Boat Launch is closed due to flooding. Visitors may carry in canoes and kayaks to the launch, but expect high water. Auburn Lake has posted a slow-no-wake advisory for this weekend, also due to high water. Long Lake boaters should check signage at the launch regarding any special wake advisories. 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 open at Mauthe and Long lakes.
