The falls are fed by a small stream that flows through the heart of residential Osceola before dropping into the glen.
The gorge walls expose layers of St. Peter Sandstone, common to the local geology of the Upper Midwest.
The site was historically known as 'The Glen' and served as a local landmark for early settlers in the late 19th century.
Cascade Falls is one of the few waterfalls in the United States located directly adjacent to a municipal downtown street.
Wilke Glen and Cascade Falls is a natural gorge located within the village limits of Osceola, Wisconsin. The site features a sandstone ravine carved by a tributary flowing toward the St. Croix River. The primary attraction is the 25-foot Cascade Falls, which drops over a limestone ledge into a rocky basin. The glen is characterized by its narrow, enclosed walls and lush fern growth. Trails provide access to the base of the waterfall, though they can be steep and uneven. The area serves as a primary example of local geological erosion patterns in the St. Croix Valley region. It remains a managed public park maintained by the local municipality.
From the wooden viewing platform at the top of the glen for a high-angle perspective, or from the base for the full drop.
Wear footwear with significant grip, as the trail surfaces near the creek are frequently slippery and wet.
The paths are narrow and include stairs; they are not suitable for strollers or those with limited mobility.
Check the water levels after heavy rain, as high flow can make the base of the falls inaccessible due to flooding.
Attempting to climb the steep, slick rock faces surrounding the waterfall, which poses a significant slip and fall hazard.
The trails can be dangerous and may be officially closed during winter months due to ice accumulation.
Stay on marked trails to prevent erosion of the fragile ravine banks; pack out all trash to maintain the natural site.
