Alpine Reality: Snow Above 2,000 Meters

Many visitors arrive in Interlaken or Zermatt in May expecting green alpine meadows, only to find high hiking trails buried under meters of snow.

Valley Trails (Open Year-Round): Walks around Lake Brienz, Lake Thun, and lower Lauterbrunnen valley are open in spring.
High Mountain Trails (Late June - Early October): Iconic routes like the Eiger Trail, First to Bachalpsee, and high Zermatt trails remain snow-covered until late June.
Peak Trekking Window: Mid-July through mid-September is the premier window for alpine hut trekking.
