Would you like to learn something about the history of Arosa's water and electricity supply or do you simply feel like discovering the mysterious botanical and geological diversity of our region on your own? Hike along the natural history trail. The trail leads from the Iselwies to the Altein waterfall and back to the reservoir. This walk is also possible in bad weather.
Enjoy the hike in July . The lady's slipper (cypripedium calceolus) is a species of orchid and flowers in the Isel/Arosa the plant loves sparse forests and calcareous soils (hence its occurrence in the Isel). The development from seed to flower-bearing plant takes 12 to 15 years.
