As we read on the website of Karkonoski Park Narodowy, the green trail section from Odrodzenie shelter to Pielgrzymy has been closed until further notice. KPN:
We are closing the trail for safety reasons. The footbridges along this trail are heavily iced over; in many places, there is what is known as “glass” – a thin layer of ice on which it is easy to lose your balance. We hope that once a stable snow cover forms, the trail will be reopened.
Park representatives add:
We remind you that weather conditions in the mountains are changeable, and icy patches may appear on trail sections above the upper tree line. Hike safely!
