I can't speak too much about how the monkeys feel about flashes, but when I visited this same spring the monkeys barely even noticed the humans at all. The springs they soak in were built by a nearby hotel to keep the monkeys out of the hotel pools. They feed them every day to keep them up and away from the hotel. (Of course, when we walked by the hotel, there was a single monkey soaking in their pool.)
