Viewing spot for the Grand Canyon

RIM

Think of the edge where you might stand to peer down at the vast canyon below—it’s not the floor or a trail, but the boundary itself.

The word "rim" directly refers to the edge of the Grand Canyon, which is a popular spot for visitors to take in the views. It’s a straightforward clue with no wordplay—just a simple description of where people stand to see the canyon’s vast landscape. Think of it like the edge of a glass, but on a much grander scale.
