While exercise is good, being ferried around while taking in impressive vistas is far better. Skip the walk and take Festungsbahn Funicular for an aerial view of the surroundings.
This incline railway is often on the itineraries of visitors to Altstadt Salzburg. But Festungsbahn Funicular isn't the only drawcard in the area. Mirabell Palace and Gardens, Mozart's Birthplace, and Salzburg Cathedral are some other worthwhile sights nearby.
