Grand Canyon
Milford Sound
Cliffs of Moher
Salar de Uyuni
Great Barrier Reef
Aurora Borealis Lodge
All these are popular natural attractions in the world. Have you explored any one of them?

I am ready to be a part of bus trips from chicago.

I am glad to know about all these attractions. These are new for me. Because I have never visited in my life, after reading this post I have decided I must go to visit all these attractions. But I want to ask if can you share some more massive information about these here. Then I will go there without any destination. Becasue I like to much travel.

I feel sad that I cannot share massive information about these attractions because I did not visit. These names are shared by my friend because he is a traveling freak and he told me about his experienced tours. By the way, When you go there so Which attraction would you like to explore first?
