It's less than three kilometers (~1.5 mile) round trip from the trailhead. The best light would be a slightly overcast day so you can get detail in the foreground without blowing out the distant formations. Sunset period would also be good. In fact the best shots I've seen are taken during late afternoon, early evening. However, if you do evening shots, bring a flashligh with you so you can find your way back without incident. Good luck! Bruce
