I've been to Hallstatt this summer. If you have time I recommend visiting the place. Next to it there is Königsee which is a UNESCO heritage site. Königsee itself is a tarn and you can literally drink from it. For this reason they only use electric and row boats to traverse the lake. I can't imagine a more suitable location for this burial despite the fact that the place is overlooked by Obersalzberg (Hitler's Eagle Nest).
