On the shortest night of the year, 21 June, the peaks of the Gastein Valley light up - impressive mountain fires create an unforgettable experience in the open air. Stubnerkogel, Schlossalm and Fulseck are open to visitors for the first time. Traditionally, a free concert takes place in the Alpenarena on the evening before Mountains in Flames (20 June), this year with Vokale Randale from 20:00.
