Serious rapids!
The falls are located in Sioux Falls at the intersection of Falls Park Avenue and Phillips Avenue. The falls can be seen from the parking lot, but you'll want to take a stroll around the beautiful park to enjoy views of the lead-in and trailing rapids, as well as the largest falls.
An online webcam from the park tower (which pans through the park to show a wonderful panorama) is available at
SiouxFalls.org.
Access Issues:
While various rumors have suggested that it is 'illegal' to run the falls, there appears to be no substantiation of that. Local (park and police) officials generally will do their best to discourage boating here due to the serious nature of the falls, but while the area is posted for "No Swimming", there are no codified sanctions against boating here.
