Niagara Falls, USA / Canada

Niagara Falls are probably the most famous waterfalls in the world. Niagara Falls are actually three waterfalls(Horseshoe Falls, the American Falls and the Bridal Veil Falls) Which sit right on the border between the United States and Canada.
The Falls drop on the highest spot from more than 50 meters and every minutes it conveys a little more than 110,000 Cubic meters of water on average. It is possible to get close to the Waterfalls and get a little wet out of the mist and hear better the roar of the water, on board of “Maid of the Mist” which is a tour-boat operating since 1846. (Not the same boat..just the same name) It is pretty common to see rainbows on sunny days due to the vast amount of mist.
