The hike to Delicate Arch is a 3.1 round trip hike with a 480 foot climb. It’s rated moderate.
The hike is very popular and you will almost never have the place to yourself.
If your mission is to have a great hike you cannot go wrong in any kind of reasonable weather. But if your goal is to get a great image, things are more difficult. You need good light with good clouds. You need to be at the top about an hour before sunset.
The arch is in a shadow of mountains at sunset starting mid-April.
I took this panorama on April 13. You can see the shadows closing in to the right and in the foreground up to the base of the arch.
