Unforgettable Places to See Before You Die

So, there's this book, see? It's called "Unforgettable Places to See Before You Die" by Steve Davey. This is the list of places he believes we should see. I tend to agree with many if not all of them. My question to all of you is: what's missing from this list? Additional questions: Which of these have you visited and of them, which do you recommend and why? I've placed a star next to the few I've seen. I really do want to see the Grand Canyon!
