...the Grand Canyon, for example.(I’d LOVE to go there sometime)

Do it if you can. Your mind will struggle with what you're seeing. Adjectives will fail you.

I've been there several times, have seen it from both north and south sides. It is big. So wide, it is not that spectacular for me.

To me, the Black Canyon of the Gunnison and Grand Canyon of the Yellowstone are more “spectacular”.
