Long Slide Falls is a 35-foot tiered waterfall on the North Branch Pemebonwon River in Marinette County, Wisconsin, south of Niagara. The river slides down four steep steps a short walk from a county park lot, and a rougher path leads to the base.
The falls
Lidar data describes a series of steep falls and cascades totaling about 35 feet in four distinct steps; other estimates put the height at about 50 feet. Flow remains fairly steady through the seasons.
Getting there
Marinette County Parks manages the falls; the park address is N20219 Morgan Park Road, Niagara. From Pembine, head north on Highway 8 toward Morgan Park to a turnout with parking, where the falls can already be heard. The walk is 0.5 mile out and back with 68 feet of gain and is rated easy.
The county charges $5 per vehicle for a day pass, good at its parks the same day. Collection begins May 1, and the entrance requires exact cash. An annual pass costs $25.
When to go
April through November is the recommended season; visitors report the falls iced over in winter.
On site
The path to the top takes little effort, while the climb down to the base is muddy and cumbersome. The county warns that viewing the lower falls involves advanced terrain. Bathrooms are available and the park is dog friendly.
