Natural wonders of the world
In no specific order, following are the places I have visited that I consider to be the greatest of the natural wonders of our world. (The Grand Canyon in Arizona would be on this list, but I’m concentrating on sights covered by ITN, those outside of North America and the Caribbean.)
Several entries from my list of Lesser Known Natural Wonders, listed at the bottom, would be in this category if they were more widely known. I have been to 183 of the 194 countries on the ITN Official List of Nations.
