"Rosstrappe" in the Harz mountains, Germany. I think the spot is quite decent with the zig-zag lines formed by the hills. I went there for a weekend, especially to photograph sunset from that spot, but also other locations in the area.
That evening, I was pretty lucky. The whole day it had been bright sun with almost no clouds, and I was mentally prepared for a totally boring sunset, but an hour before sunset some clouds finally showed up...
Another, landscape-orientation shot of the same location, 15 mins later, is among the pictures in my profile, but I liked this one slightly better, although the sun does not touch the horizon.
