In 1973 the National Park Service designated Spruce Lake Bog as a National Natural Landmark.

Spruce Lake Bog State Natural Area is a 117-acre undisturbed shallow bog lake situated in a kettle hole. Surrounding the lake is a bog forest of tamarack and black spruce. Carnivorous plants such as sundews, pitcher plants and bladderworts grow on the forest floor among bog shrubs. The rich diversity of shrubs in the swamp forest include blueberry, bog, rosemary, meadow sweet, cranberry, leatherleaf, winterberry, bog birch and speckled alder. In 1973 the National Park Service designated the bog as a National Natural Landmark. This unusual bog is a relic of the Ice Age and is typical of a more northern plant community. This area is designated as a Wisconsin Wildlife Viewing Area and is included in the national "Watchable Wildlife" program. Visitors must stay on the boardwalk trail due to the fragile nature of the bog plants, the presence of poison sumac, and the unstable bog surface.

Directions: From Dundee, WI, Take Vista Drive to Airport Road. Turn west (left) and proceed half-mile to trailhead parking.
