So you know how sometimes you go on a walk and there are cliffs or big drops and you have to be careful not to fall? Well imagine if there was a really big drop that was so big, you wouldn't even be able to see the bottom.
That's kind of like what the Grand Canyon is. It's like a really long hole in the ground that's so deep and so wide that it's really, really hard to even understand how big it is.
Now, there is something really cool that people can do when they visit the Grand Canyon. There is a special walkway that was built that goes out over the edge of the canyon, kind of like a see-through bridge. This special walkway is called the Grand Canyon Skywalk.
The Skywalk is made out of special glass that's super strong so that people can walk on it without falling through. When you walk out onto the Skywalk, it feels like you're walking on air because you can see all the way down to the canyon floor, which is really far away. Some people might feel a little scared walking out onto the Skywalk because it's so high up, but it's also really exciting because you get to see something that not everyone gets to see.
So basically, the Grand Canyon Skywalk is a special walkway that sticks out over the edge of the Grand Canyon and lets people see all the way down to the bottom of the canyon. It's like a see-through bridge that's really strong and really cool to walk on!
