Havent been to any of those. The only place that I have been to that some people would classify as "beautiful" would be Niagara Falls. It was Ok.
I personally like some of the forests I have been to. A particular one in Northern Michigan. Waterfalls buried deep in the forest, everything green and thriving. Very tranquil, very beautiful.
