We will be in Murren at the beginning of May. We were hoping to hike the North Face Trail. We know it will be cold with possible snow. Will anything be closed at this time? What else should we be expecting?
A lot can change in 2 weeks, but it is snowing around Muerren today. You can check the webcams at sites like these:
