Take the bus 521 in Thusis and get shuttled to Obermutten.
From Obermutten a Traverse starts with little challenges. An access road connects to the double black diamond Crocs trail.
After Crocs you arrive at Carschenna, where we continues the switchback dream on the Carschenna Straigt. Compared to Crocs, the Carschenna Straight feels like a playground. But it is still for experts.
Then we take a small uphill to come back to Thusis over the Hohen Rätien Trails.
