I just returned from a 12 day trip through Austria that was excellent and of course being a fan of Rick's books and video's I planned two days in Halstatt. First, Halstatt is one of the most beautiful places I have ever been and the ride across the the lake on the ferry was a thrill after the train ride. We stayed at the Gruner Baum Hotel (which was excellent in every way), enjoyed the mine tour and the Ice cave tour, attended Mass at the Catholic church, which in itself was a wonderful experience. Now for the worst: It was extremely hot for mid July, even the local's couldn't remember it being this hot in many years, but the worst part was this beautiful hamlet was literally overrun both days with bus loads of asian tour groups, I can only guess that the word has gotten out (via travel books & videos) but from 9:00 am till 6:00 pm it was shoulder to shoulder just trying to walk around in the town or shops. In the evenings most of the tour buses took their folks away so the town became more like what you would expect and the noise levels dropped and the charm returned!
Folks, I would recommend that if you plan on visiting Halstatt I would do so in the spring or fall and avoid the height of the tourist season June-August, if fact I'm seriously considering avoiding European travel in the summer and begin to go in May or September in the future.
PS: Salzburg & Vienna were amazing and I would love to go back in the near future!
