I just went to Grand Canyon Skywalk, and it was quite expensive. I drove there so I don't know how much it is if you take local tour. First of all, parking is US$20 per car, entrance fee (without even going on the Skywalk) is US$30 per person and going on the Skywalk is another US$30. Cameras are not allowed on the Skywalk, so if you want to take pictures, it has to be taken by the staff and they will charge you US$30 per picture, the more you order, the cheaper it gets. All in all, it is definitely not cheap to go to Skywalk.
