First documented by Lewis and Clark in 1804 the falls of the Big Sioux River have been the heart of Sioux Falls ever since. That site is now home to Falls Park. With the remnants of the old Queen Bee Mill and the observation tower as well as the bike trail there is something for everyone. Sit a spell at the Falls Overlook Café and have a tasty sandwich or dessert. Or wait around for the Wells Fargo Sound and Light show played at around dusk over the falls (from Memorial Day-Labor Day). Also on site is the Falls (0 comments)
