Last summer (July 2017) I was in the Faroe Islands, looking for the location of this famous place where a lake seemingly teeters on the edge of a cliff, which drops at least 100 meters vertically to the ocean below.
The images you see on the net are a bit of a trick of perspective, since the lake is actually quite a lot lower in elevation, and you must climb quite a hill to take your optical illusion photographs.
Usually cut off in such pictures, is the waterfall at the edge of the lake, which spills out the continuous rain runoff into the ocean. In this video, I did some retrospectively idiotic cliff scaling and descended about 20 meters down the side of the waterfall. Scales here are hard to capture on video - I estimate the cliffs in the distance are 200 meters tall. This is nothing special in the Faroes, as a number of places have vertical drops of 350 meters or more.
