The Welschtobelbach stream and the thundering Alteiner waterfalls make this hike through the wild nature of the Arosa mountains a true natural spectacle.

From the Arosa sewage treatment plant, the hike leads leisurely along the wild Welschtobel stream through the sparse forest, deeper and deeper into the Welschtobel valley. Soon you reach the small wooden bridge (lefthandside), over which you reach the left side of the valley. Continue until you reach the turn-off for the small Alteiner waterfall. The path leads to the small waterfall on the left on somewhat stony but not very steep terrain. The small waterfall can be admired at close range and the humid mist rises into your face. The same path leads back to the junction, where you continue to the right to the large waterfall. Soon it becomes a little steeper, always continuing towards the rock face, through blueberry bushes and leghorns and a forest. At the Alteiner Wasserfall/Alteinsee junction, a bench awaits you to rest. From this spot you have a beautiful view of the Isla. Shortly afterwards, you stand at a precipice and your gaze wanders deep into the gorge to the roaring stream, further up the water plunges into the depths. Nature shows its strength here in an impressive way. After admiring the spectacle for some time, far away from everyday life, you walk back the same way to the wooden bridge. You don't cross it again, however, but follow the path on this side of the stream through the Islaw forest. Here there are many fireplaces for a cosy picnic. If you are observant, you will discover large bushes of the protected lady's slipper here in early summer. You return to Arosa via the suspension bridge. 

Author’s recommendation

Also in Isla is the circular walk "Isel Nature Trail", where you can learn a lot about the unique nature in this area.
