Aletsch Arena spreads 97 runs across 104 km of piste of terrain. It leans intermediate at 48%, with 39 beginner runs to find your feet and 12 advanced or expert runs when you want to push.

The 2025/2026 season operates from 30 November 2025 to 21 April 2026, delivering a nearly five-month window typical of high-altitude Swiss resorts, with potential extensions into October and May when snow conditions permit. All terrain sits above 1,845 metres with most skiing concentrated above 2,000 metres, providing natural snow security throughout the December-to-April core period. The south-facing orientation captures exceptional sunshine - approximately 300 days annually - whilst higher elevations and north-facing aspects preserve snow quality.

Annual snowfall averages 4.3 metres with natural accumulation supplemented by extensive snowmaking across more than 70% of pistes using over 250 cannons, ensuring coverage reliability from early season through spring. March typically delivers peak snow depth, averaging 168 centimetres at summit elevation and 104 centimetres at base. The elevated plateau position creates consistent conditions less affected by valley inversions, and the resort reports 65 sunny days on average per season. Current season statistics show 194 centimetres base depth, 66 centimetres in the past seven days, and 382 centimetres season total as of 21 May 2026.

January through March represents optimal skiing with excellent snow coverage, quieter slopes outside school holiday weeks, and reliable weather patterns. January particularly offers insider value with lower crowds than festive periods and February half-term holidays whilst maintaining excellent conditions. December and early April provide reliable skiing with longer daylight in spring, though March historically delivers the deepest snowpack. The resort advises booking ski passes early for dynamic pricing advantages, with prices ranging CHF 53 to CHF 83 for single-day tickets depending on booking timing.

The events calendar includes the Aletsch Half-Marathon running through the UNESCO World Heritage landscape, various family-oriented programmes, and weekly night skiing on Tuesdays at Blausee and Riederalp sectors until 21:00. The Glacier Panorama Tour and Gletschi Tour provide structured ski circuits throughout winter. The resort offers "Ski for free" promotions every Saturday for children and teens under 16, and First Track Bettmerhorn early-morning sessions on freshly groomed pistes. No major terrain park or competition events feature prominently in the calendar.
