The Ski- & Gletscherwelt Zillertal 3000 are the southernmost towns in the Ziller Valley. Noteworthy is the Hintertux Glacier, which is the only year-round ski area in Austria and offers winter sports enthusiasts 365 days a year. In the winter season, it is included in the Zillertal 3000 system. In the summer, it functions as a separate resort offering 69 km of all levels of difficulty. The Zillertal Arena has its own ski pass, but is also included in the Zillertaler Superskipass system covering all resorts in the valley.
