Probably the most famous inclusion on this list, the Grand Canyon Skywalk opened in 2007 and has pretty much been the source of mass social media spam ever since.

The see-through horseshoe bridge has a drop of 240m directly below it, but it sits a massive 1,450m above the bottom of the canyon floor – quite the height. 

Although we imagine the view from the Skywalk is decent, the third option that comes up when you start typing it into Google is ‘Grand Canyon Skywalk Ripoff.’

We’re not telling you not to go there, we’re just saying you may want to explore elsewhere in the canyon first before splashing your cash!
