Kufstein is city in the Austrian state of Tyrol, with a population of ca. 18,000 inhabitants, making it the second largest city in Tyrol after its capital Innsbruck. On the west, Kufstein is flanked by the Brandenberg Alps. The Kaiser mountains lie to the south-east. The valley between the two is called the Inntal ( Tal in German is Valley ) and is where Kufstein is located. Most travellers visiting the Austrian Alps pass through Kufstein either by train, coach or car as it is the first city south of the German border at the end of the Inntal. Kufstein is known for its fortress, and is also associated with one of the best known German folk songs - the Kufstein song - which rose to popularity in the 1960s. : P70 : P8
