Author’s recommendation
Enjoy the hike in July – because then the lady's slipper orchid (Cypripedium calceolus) blooms in the Isel near Arosa. The plant loves light forests and calcareous soils – which is why it thrives particularly well in the Isel. The development from seed to flowering plant takes a full 12 to 15 years.
Derived from the technical difficulty and the stamina requirements.
