Best timing
The best time to photograph this beautiful location is probably during the early morning hours in autumn. If you are lucky, the castle might be covered in fog and the trees around the area are shining in different red and brown autumn colors. Being early at this place also makes sure that you won't have tourists in your photos. It very much depends on which look you prefer for your image. A snowy winter day or a nice sunset on any day of the year might also be a good choice for this place.
