I have visited the Grand Canyon in the past, and this has by far been the best experience in terms of views.
You first must travel to the reservation parking lot via a partially unpaved road. This road however was under construction when I visited, so I would imagine that it would be completed sometime soon. Once at the reservation, you enter the facility/gift shop where you either purchase your tickets or pickup your pre-purchased tickets/packages. From there you are shuttled to the three different attraction areas that they have, the skywalk being one of them. You can get on/off the shuttle at any of the attractions as many times as you would like.
At the skywalk, you go into the building/gift shop where they have the attraction and proceed out to the skywalk itself. Once you are outside, you must put on these felt booties over your shoes before you can walk on the glass. This is done to protect the clarity of the glass. You also get a locker that you must put all of your items in as you are not allowed to bring cameras, cell phones, or basically anything that you would carry, as they do not want anything on the skywalk.
Once out on the skywalk, the floor and walls are all glass, and you can see perfectly through them. There is a professional photographer there to take photos of you and your group if you would like, and you get a ticket to bring inside where you can view and purchase the pictures if you want to. We just bought the thumb drive with all of the pictures on them, which cost about $80 if I remember correctly.
All in all, it was great and definitely worth it as the views were amazing and by far the best of all the grand canyon rims that I have visited.
