Straight Lake State Park offers 10 hike-in campsites scattered along a forested trail, each designed for solitude rather than convenience. The park wraps around Straight Lake and Rainbow Lake in northern Wisconsin's glacially sculpted terrain, where the Ice Age National Scenic Trail passes nearby. Sites are primitive: vault toilets, fire rings, and picnic tables, but no potable water or showers. Expect to carry your gear anywhere from 400 feet to a third of a mile.
Undeveloped hike-in campground with 10 rustic, primitive sites spaced for solitude; no RV or cabin accommodations.
Weather and SeasonsFall delivers the clearest payoff. Daytime highs run mid-40s to mid-60s°F, and hardwood color peaks in late September through mid-October. Mosquitoes and horseflies retreat, humidity drops, and the hike-in sites feel genuinely peaceful. Summer brings heavy bug pressure that reviewers cite as the main seasonal tradeoff. Expect moderate weekend crowds during peak color, but solitude is easy to find on weekdays.
Natural Features and SceneryAncient glaciers carved the rolling, forested hills that cradle Straight Lake and Rainbow Lake across more than 2,000 acres. Mixed hardwoods dominate the landscape, turning brilliant shades of red and gold in late September through mid-October. Short trails loop past quiet ponds and climb to overlooks where forest meets water. The park sits at 1,283 feet elevation. Reviewers consistently mention the scenic quality of both lakes for paddling and the well-maintained condition of the trail system, though signage can be sparse.
