Overview
The Porcupine Lake Wilderness protects 4,446 acres of Wisconsin northwoods in the Chequamegon portion of the Chequamegon-Nicolet National Forest. The 4-mile loop around Porcupine Lake is the primary way to experience this wilderness, and it delivers the defining qualities of Great Lakes backcountry: a spring-fed glacial lake, balsam fir and paper birch pressing close to the water, the call of common loons in the morning. No motors, no groomed trails, no crowds.
The Porcupine Lake Wilderness is one of the smaller federally designated wilderness areas in the Midwest, but its compact size does not diminish its character. The lake itself is exceptionally clear spring-fed water over a sandy bottom and the surrounding forest has an old-growth character in places, with trees of varying ages and the snags and down logs that a managed forest typically removes. This structural complexity supports the diverse bird community that draws birders from across the region.
The loop is short enough to complete in a half day, making it a good option for a morning hike followed by an afternoon on the water or in town. It is also suitable for an easy overnight if you want the experience of camping in a federally protected Wisconsin wilderness.
The Route
Miles 0 to 1.5: From the Forest Road 213 trailhead, the trail enters the wilderness boundary within a quarter mile. The change in trail character is noticeable: no crushed stone, no mowing, just natural surface threading through the forest. The first section passes through a young stand of aspen and birch a sign of a past disturbance, likely a windstorm before entering older mixed forest.
Miles 1.5 to 3: The trail reaches the north shore of Porcupine Lake and follows the shoreline east. This is the highlight of the loop: open views across the lake, a flat rock outcrop good for a lunch break, and the probability of seeing loons if you visit in summer. A spur trail leads to a tent site on the northeast shore, set back the required 200 feet from the water.
Miles 3 to 4: The southern leg of the loop moves through denser forest away from the lake and returns to the trailhead. The trail is less defined here and requires some attention to the blazes on the trees.
When to Visit
Late June through September is the sweet spot. Blackflies can be significant near the lake in June insect repellent is worth packing. Fall color peaks in late September and the wilderness is particularly beautiful as the birch and maple turn. Loons are present from roughly mid-May through early October.
Check conditions before visiting in spring or after major windstorms, which can drop trees across the lightly maintained wilderness trails.
What to Bring
- Many hikers carry 1-1.5 liters of water. Lake water is available if treated properly. Individual needs vary.
- Insect repellent, particularly June and early July
- A map or downloaded trail file: wilderness blazes can be subtle
- Bear spray is an option; bears are present
- For overnight trips, a bear hang kit or bear canister see bear canister requirements
Practical Details
