The hike to Abiqua falls was very fun and my time at thee falls even better, with exception to the 10+ minutes I spent standing in my underwear in the water trying not the fall in.
I would do things slightly different next time but I would still do it. The water was not so cold it was unbearable but cold enough to not be thinking clearly. I took a few different compositions closer to the shore with rocks as a foreground but missed an image for a focus stack from trying to hurry.
All said and down, I enjoyed it very much. If you are going to go, bring a good vehicle, be prepared to walk a little extra and the sun rises behind the water so the morning light looks great.
