Would someone be able to recommend activities in and around Wengen. We are staying in an airbnb in Wengen with a family of 6, including 2 grandparents and 2 children ages 8 and 9. Looking for some easy hikes, waterfalls, playgrounds - we are only there for 2 days from Paris arriving by train.
Would you recommend we buy the Swiss half fare cards if we needed a form of transportation to sightsee?
