We drove past Hydnefosen on 21 July 2007 and there was a lot more water falling. I would like to add that when we saw these falls while driving on the road (Route 52 heading north/northwest), they looked very high compared to the surrounding valley. I remember thinking that this was something out of Lord of the Rings. The cliff was in shadow, as it was rather late in the day. Alas, we did not stop and I have no photo, only my memories.
