Kettle Moraine State Forest—Northern Unit Current conditions

Conditions as of Friday, April 11, 2014:


As of April 11, all trails in the forest are open to hiking; however, there are still some wet and muddy stretches to be found.  The horse and mountain bike trails remain closed to prevent long-term damage.  Please check back with us again later this month regarding the opening dates for these trails. 

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


Long Lake Campground is closed for the season, and will re-open May 2, 2014. 
Mauthe Lake:  The 500s loop is closed until April 26th, but the rest of the campground is open for camping and reservations.  The entrance will be staffed weekends in April, but weekday campers may self-register for campsites and vehicle stickers at the entrance station. 
Greenbush Group Camp is is closed for the season, and will re-open May 2, 2014.
New Prospect Horse Camp  will remain open for hunter access through Dec. 15, and will be gated closed on Dec. 2.   The 2014 camping season begins May 2.
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 ski season, and will re-open April 1.


Chorus frogs, wood frogs, and spring peepers have all come alive this past week, and are being heard from many small potholes within the forest.  Bluebirds, killdeer, turkey vultures, and phoebes are also recent arrivals, and Tom turkeys have been strutting their stuff in the fields.  Skunk cabbage has emerged, and will soon be joined by other early-spring flowers.  


Mauthe Lake is nearly ice free, and other lakes within the forest are losing their ice fast.  Canoe and kayak season will be right around the corner!


The spring turkey youth hunt is April 12-13th, and the regular spring turkey season runs April 16th through May 27th.   Reminder that firearms are allowed in the Zillmer trail area during spring turkey season, and brightly-colored clothing is recommended for visitors venturing off-trail anywhere in the forest.  About 95 percent of the state forest [PDF] is open to public hunting during established open seasons. Hunting and the discharge of firearms, air guns, or bows is not allowed in the Mauthe Lake and Long Lake recreation areas or the Greenbush Group Camp.

Some seasons may be subject to change. Consult the Wisconsin Hunting and Trapping Regulations before going hunting. Target shooting is prohibited in all areas of the forest.
