8Chichen Itza Pyramid, Mexico

You might be surprised to see Chichen Itza on this list because it’s considered one of the most popular tourist attractions in the world.

However, even though you can come there, recently it’s strictly forbidden to climb it. The ban was issued after a woman tumbled off the pyramid on her descent in 2006. This event had a tragic ending and, to avoid anything similar from happening in the future, it became closed to the public to the disappointment of multiple tourists, striving to reach the top of Chichen Itza.
