Arches NP, UT ****
Pros: Arches everywhere, Delicate Arch, colors change with time and season
Cons: too many people trying to take a perfect photo of Delicate Arch
I visited the park back in 2012. The main highlight of the park is Delicate Arch. While you can see it from the lower viewpoint, it’s much rewarding to hike to the main viewpoint which is a steep ~1km walk up. It is very popular place, especially at sunrise and sunset.
