Based on this listing's approximate location — see the note on coordinates below.
Great Falls is a horseshoe-shaped waterfall viewed from overlooks near the historic Falls City Cotton Mill at Rock Island State Park in Warren County. The waterfall’s flow is controlled by the upstream TVA Great Falls Dam, making water release unpredictable; check the dam’s discharge schedule before visiting to see the falls at significant flow.
Swimming and wading are prohibited downstream of the powerhouse at all times. Dogs are allowed on leash. The overlook is free and accessible from parking areas near the historic mill site, which offers additional cultural interest.
Any time; flow controlled by TVA dam release schedule, so check discharge status in advance.
