Best day trips from Interlaken in September

Go shopping in Interlaken in September

  • When: Mid-to-late September 2026, event-dependent by village
  • Where: Habkern, Beatenberg, and Grindelwald village routes
  • This is your best shot at September-specific shopping: Alpkäse, dried sausage, small farm goods, and practical local food gifts. Go where the procession ends, not where it starts.
  • When: Daily through September, best before noon
  • Where: Central bakeries around Bahnhofstrasse and the old town streets
  • Look for Zwetschgenwähe, braided Zopf, and simple chocolate gifts that travel well. Morning stock is fresher, and smaller bakeries often sell out of fruit tarts by lunchtime.
