Have you looked at the Horseshoe Bend Overlook. It's an incredible piece of nature, but only a fool would walk up to the edge.
@ConstitutionRose I went to the top of the Eiffel Tower in Paris years ago.
"Constructed from 1887–1889 as the entrance to the 1889 World's Fair, it was initially criticized by some of France's leading artists and intellectuals for its design, but it has become a global cultural icon of France and one of the most recognisable structures in the world.[3] The Eiffel Tower is the most-visited paid monument in the world; 6.91 million people ascended it in 2015.
It is about the same height as an 81-storey building, and the tallest structure in Paris. Its base is square, measuring 125 metres (410 ft) on each side. During its construction, the Eiffel Tower surpassed the Washington Monument to become the tallest man-made structure in the world, a title it held for 41 years until the Chrysler Building in New York City was finished in 1930. Due to the addition of a broadcasting aerial at the top of the tower in 1957, it is now taller than the Chrysler Building by 5.2 metres (17 ft). Excluding transmitters, the Eiffel Tower is the second tallest free-standing structure."
There is a core of the building and at the top there is an open air observation around the core of the building where the elevators are. I felt the open air area reaches into heaven as it is so high.
People, including my husband, were leaning over the rails and taking pictures. I could not stay where the rails are. I stayed toward the center structure. I kept telling myself it had been there since the 1800s and would still be there when I left. I still wanted down from there. We had dinner in the tower restaurant and I felt safe there - it was just that open air showing one the entire world (that is what it felt to me) that I couldn't handle.
