Stubai Glacier is small but steep, with 22 runs and 68 kilometres of piste dropping 1,515 metres from 3,212 metres to the base at 1,697 metres. The difficulty mix is unusually demanding for a glacier: 35% advanced and 11% expert, against 32% beginner and 22% intermediate. From Mutterberg, the Eisgratbahn gives quick access to the high sectors and the Gamsgartenbahn serves the gentler slopes, which makes Gamsgarten the practical base for families and lessons, while the Eisgrat side suits skiers who want to reach the upper glacier quickly.

Advanced skiers head towards Schaufeljoch and the more exposed upper glacier, and the Daunjoch triple chair, restricted to advanced skiers, serves the hardest terrain, including a black run of more than three kilometres. The Wilde Grub'n is a 10-kilometre descent billed as the longest glacier run in the Alps, and the Daunferner sector has steep couloirs for freeriders. Powder Department routes are marked on a separate map, with freeride checkpoints at Eisgrat and Gamsgarten, but unsecured terrain should only be entered with the right equipment and knowledge.

The 2025-2026 season opened on 19 September 2025 and runs through 17 May 2026, delivering an eight-month operating window that ranks among the longest in the Alps. Glacier terrain and elevations exceeding 3,000 metres enable reliable early autumn and late spring skiing when most conventional resorts remain closed. The season typically begins in mid-to-late October depending on conditions, though early snowfall in autumn 2025 permitted operations from 3 October.

Annual snowfall averages 6-9 metres at glacier elevations, with historical maximums reaching 13.87 metres and minimums of 6.39 metres across recent seasons. The resort maintains snowmaking coverage on the lower valley runs, though the glacier's natural accumulation typically provides consistent base depths throughout winter. High-altitude, north-facing aspects preserve snow quality well into spring, whilst exposed ridgelines can experience significant wind transport affecting measured totals.

Peak powder conditions occur from December through February, when cold temperatures preserve snow quality and storm cycles deliver fresh accumulation. Spring skiing from March through May offers softer corn snow and warmer temperatures, with the glacier terrain receiving strong solar exposure at midday. October and early November provide autumn training conditions for professional athletes, whilst mid-November marks the beginning of regular public operations with fuller lift access.

The FIS Freeski World Cup Stubai, held annually in November at the Stubai Zoo snowpark, has hosted the slopestyle season opener for nine consecutive years. The INTERSPORT Testival runs in mid-November, with over 20 brands presenting new equipment for on-snow testing. The BIG Family programme runs throughout winter with weekly piste basher rides and children's activities at Gamsgarten.
