This all day excursion was a wonderful experience. Karin was a great guide and host. The hike through the Grand Canyon of Austria had the clearest water I have ever seen in a river. Karin took the small group up to a look out point, showing us a mountain near by, while also allowing for observation of the canyon below. I cannot say enough good things about Karin, she is an excellent guide. This is definitely worth the trip and I would highly recommend it.
