shedd aquarium: I am planning to visit Utah/AZ in May last week. I wanted to know what time of day is best time to see these two places. I heard Antelope canyon can be best seen between 12-2 PM. Is that true? What if I am late or early to this place. Is it still that beautiful for photography purpose??? How about Zion national park? Can I club any two parks/places in one day? If yes, what are those two. :)|||Definitely early morning or late evening. The heat isn't as rough. I was there last summer and got to watch the sunrise in the valley. If you get there early enough (4:00am) in the morn, you should be able to see a lot of the Milky Way
