The Zillertaler Alpen constitute the border between Austria and Italy, North and South Tirol, near the Brenner Pass. The central part is packed in glaciers, but of course also here the ice melts. Much of this mountain area is protected, and therefore a hikers paradise. The Hochfeiler / Gran Pilastro is, with its 3510 m, the highest peak. The Zillertal Alps is one of the most popular areas in Austria for the adventurous trekker and mountaineer. Between the about 30 huts, one can make numerous trips, often including the crossing of glaciers.

The popular Berliner Höhenweg located in this area, and this route does not involve crossing of real  glaciers. Also, the Via Alpina traverses the Zillertal Alps. On the Italian side one will find the Pfunderer Höhenweg. On the Italian side are fewer glaciers and more trails.

The area to the north is best reached via Mayrhofen. On the Italian side best start is St. Jakob or St. Johann.
