I drove up to the South Rim last Saturday. Got there around 4:30 in the morning because my cousin said sunset is the only time to go. I think that's wrong. The sunrise light hits the rock walls different. Makes the reds and oranges pop way more than the hazy gold you get at dusk. Plus there were like maybe 20 other people there. No crowds, no one bumping into me with a selfie stick. By noon the place was swamped with tour buses and kids screaming. I sat on the edge near Mather Point for almost two hours just watching the shadows move. Has anyone else noticed how the colors change faster in the morning compared to evening?
