The world's largest transnational waterfall - Niagara Falls

After four years, seeing Niagara Falls again, without snow and sunshine, the majestic Niagara Falls still retains its powerful presence. The roaring sound of thousands of horses is incessant, and the spray is mixed with the endless flow of time, year after year. I personally recommend staying at the Hilton Hotel, where from the upper floors you can see the waterfalls of both countries, and even have a full view of the American city across the river. The sightseeing tower is all in sight, which is really super awesome.
