Skywalk
If you decide to visit the Grand Canyon, you should definitely go and see the sky walk. You get to walk on glass and have the opportunity to see the Canyon from almost every possible angle. It is built about 4000ft above the Colorado River Valley. The floor is transparent so you can look down, almost similar to the one in the CN tower. You probably didn’t know this but the skywalk can hold up to 71 million pounds! Also, it has the ability to withstand a magnitude 8 earthquake. It cost about 30-40 million dollars to construct this walkway and if you do decide to visit, the cost is $25 per person.
