If I have time to only visit one National Park this summer, which park should it be and why?
I'd have to put in a vote for the Grand Canyon National Park. To say that it's beautiful is a serious understatement.
I'd vote for Arches National Park as a very close second. If you've ever wondered what people are talking about when they talk about "Western Skies" this place will clear that up.
