High Cliff State Park
🏔️ Trusted Guide to Wisconsin’s Niagara Escarpment – Updated 2025
Ancient Cliffs Above Wisconsin’s Largest Lake
Perched atop the Niagara Escarpment — the same limestone formation that creates Niagara Falls — High Cliff State Park commands sweeping views over Lake Winnebago, Wisconsin’s largest inland lake. This 1,187-acre park is the only state-owned recreation area on the lake’s shores, and its dramatic limestone cliffs, 1,000-year-old effigy mounds, and 19th-century lime kiln ruins layer natural beauty with centuries of human history. The park sits on Calumet County’s northeastern shore, where the escarpment rises sharply above the lake — creating vantage points that stretch for miles across open water.
Effigy Mounds
The Indian Mound Trail winds through a sacred landscape where nine effigy mounds — including a remarkable 285-foot panther mound — survive from the Woodland period (roughly 1000-1500 A.D.). Built by nomadic Siouan-speaking peoples, these earthworks originally numbered around 30. The remaining mounds include both long-tailed and conical forms, with interpretive signs explaining their cultural significance and the people who built them.
Lime Kiln Ruins & Industrial History
From 1856 to 1956, limestone quarried from the escarpment was heated to 2,200°F in massive stone kilns to produce quicklime for construction. The Lime Kiln Trail passes the remarkably preserved ruins of these industrial structures — stone arches and chambers that now stand as atmospheric monuments to a century of Wisconsin’s industrial past.
