I just hiked it on November 1st. Not peak season, for sure, but it wasn't super busy. I applied for, and got, a permit in their lottery. Though if you got to the Angel's trailhead before 10am, there wasn't a ranger to check, anyway. Highly recommend the hike. Unless you hate heights like the two women I met. Another guy and I carefully guided them back to the trailhead after they got to a point where they froze from being freaked out.
