One gets the best views of Burghausen’s picturesque castle (and old town center along the Salzach river) from the Austrian side of the river, along the river bank at the village of Ach (first two photos), as well as the vista point higher up in Duttendorf (third photo in the gallery below).
A foggy December evening (it was only 5:20pm when I made these photos, close to the end of December and the shortest days of the year) added some nice mysterious glow to the scenery.
