Wisconsin State Park System Ahnapee State Trail
From downtown Sturgeon Bay, this 48-mile, county-operated trail winds south along the beautiful Ahnapee and Kewaunee rivers to Algoma, Casco, Luxemburg and Kewaunee, passing by a mixture of evergreen glades, farmland, prairies and wooded areas teeming with wildlife and native wildflowers.
Near Sunset Road in Kewaunee County, the trail branches off in three directions, west to Luxemburg, northeast towards Algoma and southeast towards the city of Kewaunee.
The trail may bring a number of different users to the trail at the same time. It is important to use good trail etiquette to ensure the enjoyment and safety of all trail users.
Walking and bicycling
The level grade and limestone surface make this trail suitable for bicyclists, walkers and joggers. Bikers do not need a trail pass while using the trail. Due to the possibility of hoof marks in the trail surface, wider-tire bicycles are recommended.
Pet owners, please be sure to have your pet on a leash, 8 feet or shorter, at all times. You must pick up after your pet.
Ice Age National Scenic Trail
The Ice Age Trail follows two sections of the Ahnapee State Trail corridor, for about 17 miles from downtown Sturgeon Bay to Algoma and for another 10 miles from the city of Kewaunee through the C.D. Besadny Fish and Wildlife Area to County Highway A.
The Ahnapee State Trail corridor is open for horses from April 15 to November 15. Riders are asked to limit their use of the trail immediately following a heavy rainfall to reduce the amount of damage to the trail. Riders must pick up after their horse.
Snowmobiles are permitted on the trail. Operators must follow all Wisconsin snowmobile laws. The trail also connects to numerous miles of county snowmobile trails.
The trail is open to cross-country skiing and snowshoeing, however, the trail is not groomed and skiers and snowshoers must share the trail with snowmobiles. Skiers do not need a trail pass while using the trail.
No Hunting and trapping allowed on trail
Hunting and trapping are not allowed on the trail corridor. For more information, please see:
A portion of the Ahnapee State Trail property in the town of Algoma is more than 100 yards from the trail corridor. This portion is open to hunting and trapping during the Wisconsin state parks hunting time frame.
