The little town Heiligenblut in Kaernten is the gateway to one of the most famous mountains in Europe, the Grossglockner. An old little town - in these days a little occupied with tourists - offers a splendid sight of the mountain. Most times of the year the peak of the Grossglockner is hidden in clouds, so you have to have a little luck seeing it.
A good idea is to try this in the morning, the chances are better to get a look. Heiligenblut is a good starting point to visit the Grossglockner itself, driving the Hochalpenstrasse with many exciting views. You can also start here several hiking tours.
