Tröllafoss was an exercise in frustration when I went looking for it on my trip to Iceland. First of all, you have to follow a rough 4wd path. Although there was a sign at the start of the rough drive for the falls, there wasn't one as you got closer to the falls so you had no idea where to stop the car. Then, I had to walk until I finally heard the falls, but the scramble to its bottom looked very dangerous and I didn't try to tempt fate. I know there are horseback excursions to this waterfall, but we didn't have the time (nor money) to make the arrangements. So this photograph was the best that I could do.
