Hi James:

I don't see my previous reply, so I must have pushed the wrong button.

In any event, What I said was that I don't think you can go wrong following Dave's advice. The Watchman is good for both sunrise and sunset, but is probably more popular at sunset. The easiest and most popular access is from the bridge near the Canyon Junction Shuttle Stop. (Which is where I suspect Dave took the shot posted here from.)

Another good sunrise location, especially if you are staying in Springdale, is the "Towers of the Virgin," Easiest access is from behind the Zion Museum. I have never tried it, but you can also view it from the end of the Canyon Overlook Trail.
