Love lists like this.
You can see #1 (Antelope Canyon), #9 (The Wave, Arizona, USA), #13 (Grand Canyon) and #30 (Bryce Canyon) all in one week with a cheap flight to Phoenix and a rental car. That's 10% of the list right there.
The Wave is definitely one of the coolest natural wonders you'll ever see on this planet. It takes some planning, and you need to apply in a lottery for permits, but well worth it.
Would have to put Iguazu Falls and Perito Merino glacier, both in Argentina, up there as personal favorites as well.
I used to have a travel thread on Beyond. I used to be somebody.
