In 1829 the ancestors of Family Putzer bought the property and started catering food and drink to the very few hikers walking from Nova Levante to Carezza at the beginning. Back in 1862 it is narrated that during the weeks when hay was harvested on the medows of Carezza farming people went to the ADLER celebrating with music and dancing, which was much practiced in those days.
In 1893 the Hotel ADLER was enlarged in today’s size, and in 1906 got the new panoramic Veranda facing east. Since almost half a century the new street through Val d’Ega was opened allowing a better communication between the railway station in Bolzano and the Dolomites mountains of Rosengarten and Latemar. Travellers were using post-carriages, riding horses or walking, having a stop at the ADLER, then a Post-Hotel.
After most of the peaks of the Dolomites had been first climbed, in 1909 the Great Dolomites Route was opened connecting Bolzano through the Val d’Ega, passo Carezza (Costalunga), Val di Fassa, Passo Pordoi, Passo Falzarego to Cortina d’Ampezzo, giving access to this unique breathtaking mountain landscape to those not wanting to climb into the mountains. From 1950 tourism once again changed. Now the period began where an increasing number of tourists were travelling by their own means. And in 1950 skiing became available in Carezza Ski, among the very first ski resorts in the Dolomites. In 1976 and 1984 the entire hotel was rebuild, offering a better service, and years later to come many small benefits have increased the wellbeing at the ADLER, among those in 2009 the newly build sauna and relaxation area. In 2009, too, the Dolomites were proclaimed UNESCO World Natural Heritage.
