Graz, Capital of Styria
Tours > Provinces

At the foot of the Schlossberg are among other things the Herrengasse, a Baroque boulevard, the Landhaus with an arcade court from the Renaissance, the city hall, and the city's parish church.
Duration of the trip approx. 10 hours; the journey between Vienna and Graz lasts approx. 2 1/2 hours.
Of course you can take trips from Vienna in the provinces.
These last depending on the distance half or full day. For more intensive sightseeing I recommend two days.
