We paid $10 for parking on that side of the USA which was reasonable for us. Received a free map. We walked over the Rainbow Bridge. Need to show your British passport. Enjoy the waterfall spectacle while walking. Then found a nice restaurant for a drink and a view of the waterfall. Awesome experience. Then walk across the rainbow bridge. You need a return fee of one dollar per person. We grouped for a coupon for Friday American restaurant. When we arrived, the guy said to go see the waterfall after dinner, the idea was great. We stayed at a motel for $50, including continental breakfast for four of us. We paid more domestically than this. The next day, we walked along the edge of the United States, very natural, very beautiful, can feel the mist when taking pictures on the American side and the Canadian side.
