There is no mobile phone communication signal in ten miles near the Grand Canyon, and there is no WiFi in the scenic area, so you must print the confirmation code before you can go to the scenic area to handle the tickets. Helicopters must be taken, it is very worthwhile, if you take the plane, glass bridge can not go, the second and third scenic spots are most worthwhile to go, the first scenic spot outside the scenic area, you can also see by yourself. Overall, it's well worth it.
