There's several routes to see the Grand Canyon, via the West Rim, the North, or the South Rim. I took the latter because the West required a tour package to enter and would require spending most of the day there.
Regardless, there's a grand view in almost every spot along the rim that panoramas and even Street View can't show you. Expect to spend at least a few hours over here, with some priority on the Observation Station (for a bit of history) if you arrive late and the Visitor's Center closed.
There were so many people watching the sunset that it's hard to get a good wide-angle picture without anyone in it.
Note: I know a friend who attempted one of the trails three years back, I'm not sure if she completed it, but it's hard to get a full view of the canyon from the South Rim, so maybe I'll attempt to go down one of these trails at some point or another.
