According to me its depend on what kind of nature lover you are for me i love to explore the wild life so definitely South Africa is the one. and the other one is Niagara Falls in Canada because i love the nature. So its very difficult to answer this question because each and every country has his own culture, diversity. So for me all county's are beautiful even i had not been visited them yet.
Switzerland is one of the beautiful place in the world. I love to visit it once more.
I live in South Africa. It is a beautiful country on it's own with the exception of the crime. I have travelled to many places around the world and one of my ultimate destinations would be the Greek Islands.
In my opinion, in terms diversity, SPAIN, and ITALY
have a great mix of hills, beaches, and spectacular city life. Also THE FOOD!
They're all beatiful in their own way, but if I have to choose I'll pick Brasil
