I visited this WHS in April 2014. It is quite hard to understand why such a site is not inscribed as a mixed site at least when it has such a natural setting. The wooden houses are really picturesque and there is an interesting World Heritage loop trail which gives you an interesting overview of the city. The WH Museum is an interesting place to visit to better understand the OUV of this site. The highlight of my trip were the painted skulls in the Beinhaus. They are really unique and just outside there is a tiny graveyard with a wonderful view of the mountains and lake. I was one of the only European tourists around. The vast majority were Asian tourists - I think it must be among the Top 10 places Asian tourists visit in Europe for some odd reason - no wonder the Chinese built a replica!
