Hallstatt is a scenic village in Austria. It is home to the oldest salt mine in the world and the Heilbronn Circular Trail.
This Trail is ideal for families who like hiking. Part of it is at the foot of the Dachstein mountain where there are sea creature fossils as well as information boards that allow people to look back over millions of years to a time when the Dachstein was still seabed.
It takes about 3 hours to complete the trail and a cable car is available for a return trip. Read more here.
