Why Salzburg for a city break?
Salzburg is one of the most beautiful small cities in the world — a baroque city of extraordinary completeness, set dramatically between the Hohensalzburg fortress on its rock and the Alps rising immediately behind, with the Salzach river dividing the old city from its newer residential quarters. Mozart was born here in 1756 and the city wears his legacy with an intensity that verges on the religious. The Salzburg Festival, held each July and August in the fortress and the surrounding theatres, is the finest music festival in the world. The Sound of Music was filmed here, and the associated tourism is unavoidable.
From most UK airports it's around two hours ten minutes — direct flights from London and connections from regional airports. Salzburg Airport is 4km from the centre (bus €2.60, 20 minutes). The city is compact and entirely walkable. Go in summer for the festival and the Alpine walking; in December for the Christmas markets (Salzburg has the most atmospheric Christmas market in Austria, in the cathedral square and around the old town). January and February are quiet and very cold but the surrounding ski resorts are at their best.
