Be sure to have a full tank of gas, because Linz is well worth a detour. Situated 60 miles from Mitterberg, it has some terrific attractions, such as Linz Castle Museum and Lentos Art Museum. Get set to start racking up those miles, because Minimundus and Landhaus are also worth a day trip. You’ll discover these popular attractions in Klagenfurt am Woerthersee, 60 miles away.
