The world-famous Niagara Falls is one of the seven wonders of the world. Located on the Niagara River between Canada and the United States, it shocks all visitors with its abundant moisture and magnificent momentum. When we have not seen the waterfall, we have heard the sound of rumbling, flowing and pouring. It's like thunder piercing through our ears, and the Niagara Falls are coming into our eyes. We came to Niagara Falls in the hottest season. As soon as we stepped into the Grand Canyon, we felt a refreshing gust. The breeze blew away the heat and brought the cool. Take the "Misty Girl" cruise boat and sail into the waterfall. At first, only a few sprays hit us naughtily. Later, when we entered the waterfall, a strong current came nearer and nearer to us, and the spray hit our raincoats more frequently. The sky-high mist covered the bright sunshine and enveloped us in a mysterious and spectacular world. With our backs to the sunshine and the mist, rainbows of seven colors emerge and disappear from time to time. This is not so much to watch the waterfall, but to experience the waterfall first-hand, instantly convinced by the tremendous power and infinite charm of nature.
