Canyonlands - Needles Arches

Planning a trip to the Needles this spring and was wondering if anyone knew when the best time of day is to photograph the various arches. The only thing I've been able to find is that Druid is good in the early morning.

How about Angel, Castle, Fortress, etc?

Angel Arch is a morning shot but it might also look good in the afternoon with opposite light, if you stand in the shadow of the Molar.
See my trip report to Angel Arch and All-American-Man.
