Willow River State Park spreads across 2,800 acres of rolling countryside in northwest Wisconsin, anchored by Willow Falls, a multi-tiered cascade that drops through a rocky gorge. The park offers 156 campsites (tent, RV, and group), a sandy beach on Little Falls Lake, and miles of trails. Admission requires a vehicle sticker; firewood is sold on-site.
Multiple family and group camp loops with a mix of electric and non-electric sites; group camping areas are available.
Weather and SeasonsFall is the standout season. Mid-40s to mid-60s°F daytime highs (September through October) bring brilliant hardwood foliage that frames the falls and gorge. Nights are cool and crisp. Mosquitoes decline, and autumn rains often boost water levels, making the cascades more dramatic for photographers. Crowds are moderate but spike on peak foliage weekends. Summer draws families for swimming and paddling, but expect heavy use on weekends and occasional parking struggles. Water systems are on seasonal shutdown and will return in spring 2026; until then, drinking water is available at the park maintenance building, and vault toilets are scattered throughout. The park is open year-round from 6 a.m. to 11 p.m. Bike trails close briefly from November 15 to December 15.
Natural Features and SceneryWillow Falls is the main draw. Water tumbles through the Willow River Gorge in a series of drops, creating one of the most photographed features in Wisconsin's state park system. The gorge itself cuts through ancient rock formations, with steep walls and dense forest canopy overhead. Beyond the falls, Little Falls Lake offers a sandy swimming beach and calm water for paddling and fishing. The park's 2,800 acres include a mix of hardwood forest and open prairie meadows. Elevation sits at 919 feet, with rolling terrain that varies from flat lakeside paths to steep gorge approaches. In fall, the hardwood canopy blazes with color, especially vivid against the grey rock of the gorge.
