The hills really are alive when families visit Salzburg as part of an Austria vacation. Best known as the setting of the popular musical The Sound of Music, it has even more musical history chops, being Mozart’s birthplace and a key location throughout classical music’s development. But it is also incredibly kid-friendly, with its walkable city center, themed bus tours and green space galore. Salzburg pairs perfectly with time in Germany or elsewhere in Austria, and fun day trips include salt mine tours or Alpine toboggan runs. Kid-friendly hotels range from large luxury properties with all the bells and whistles to charming boutique properties that cater to children in a personal way. Just outside the city limits lie country resorts with loads of onsite amenities in gorgeous rural locations.
