Jungfrau Region Easy-Going Family Tour
First Mountain Cart, the Brienz Rothorn steam train and a waterfall valley, a relaxed route for families.
Based on the official family-week itinerary and family guides, we picked the highlights kids love most: the Harder Kulm funicular, the Mountain Cart and Bort playground at First, the Brienz Rothorn steam train plus a lake cruise, and the Lauterbrunnen Valley waterfalls. We skipped the pricey, high-altitude Jungfraujoch on purpose. Each day has only a half- to full-day activity, leaving time to rest.
The Rothorn steam train generally runs from June to October; the Mountain Cart is open in summer only.
