The tour we did was both the American and Canadian side. Which we though was absolutely worth it. The only real stop on the American side we did was to ride the maid of the mist and the tower,, so if you can not cross the border in to Canada with out issues, this is NOT the specific tour for you. The company does offer American side tours only, but based on reviews they are not nearly as good, so check those r out and make the decision based on the latest reviews!!
