Kaieteur Falls from the air, Guyana, South America. Kaieteur Falls in the tallest single-drop waterfall in the world at 741 ft. in height, and the second tallest waterfall period.
This photo was taken out the window of a 6-seater airplane as it approached the falls. Our pilot was kind enough to circle the canyon a couple of times to give us the best view possible. It really is the most amazing natural landmark I've ever seen.
