Grand is an understatement. A gorge so massive you don't feel vertigo until your at the edge. Make sure you have a high zoom camera, a hat and some sunglasses, and a Gatorade because it gets very hot! If you visit the Skywalk you will get a thrill! They wont tell you the glass panels under you has a gap in between them so you will think your walking on suspended glass. Also no personal photos on the skywalk can be taken. Collect your thoughts on a fine day at the Grand Canyon. What seems significant at the time seems insignificant compared to the view you get looking down in the Grand Canyon. Note: no railings - all view! Welcome to the inverted Cathedral of the USA.
