What I love about it is that more than any other park I've visited, it defies description. I adore Yosemite and Joshua Tree, for example, but I believe they can be understood from photography. Grand Canyon feels like it can barely be understood in person, like just the idea of it is too big or complex to hold in your mind and that is thrilling for me.

Along that line, there is no way a photo or video will do justice for Angel's Landing in Zion, or for Carlsbad Caverns.

(Though I hear Zion has gotten even busier in the last few years, that's not great.)
