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 - All campsites are now open and reservable for the season. The Entrance Station is open Fridays thru Sundays for stickers and firewood. Weekday visitors should use the self-registration by the entrance bulletin board. Flush toilets and showers are now open as well; however, the beachhouse remains closed. Firewood may be purchased from any local vendor within 10 miles, including Zahn's Trading Post (New Prospect) and Dins Mini Mart (Dundee).

Backpack Shelters: Shelters 1-5 on the Ice Age Trail are open and reservable year-round. Shelter 6 on the Zillmer Trail is now also open for the season, and reservable through November. Backpack shelter sites are very popular on weekends, and we suggest planning your backpack camping trip early.


Spring is here! The turkey vultures, pee-wees, bluebirds and song sparrows are recent arrivals, and the chorus frogs have just begun to sing. Ice is out on all the lakes, and we've had some sitings of bald eagles and loons fishing on Mauthe Lake.


The boat boarding docks are in place year-round at Mauthe, Auburn and Crooked Lakes. The boarding dock at Long Lake will be installed before the fishing opener on May 2nd.

The fishing pier at Mauthe Lake is also year-round. The fishing pier at Long Lake will be installed before May 22nd for the Memorial Day weekend.

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


The spring turkey season is April 15 through May 26. Visitors venturing off-trail should consider avoiding the colors red, white and blue – the colors of a turkey's head.

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.
