Alongside the Grönbach stream in the secluded Justital valley, past the site of the famous "Chästeilet", or annual cheese sharing. Between steep mountain flanks further into the valley, from where it is plain to see how the Sichelpass (Sichel = sickle or crescent) got its name.
The Justistal, the entrance to which is clearly marked by the distinctive Niederhorn, is a snow-sure winter paradise. Its name comes from Justus, a monk who once spread the gospel in the Lake Thun area together with his fellow monk and companion Beatus.The groomed winter hiking trail starts in a gentle descent from Grön, running parallel to the cross-country skiing trail alongside the Grönbach stream, which flows into Lake Thun in Merligen. Glittering ice formations, created each winter anew, flank the trail. The route continues past the Spycherberg, which sets the stage every autumn for the legendary "Chästeilet", in which the cheese from a summer’s alp grazing is divided between the farmers according to their cattle’s milk yield.From here, the impressive, maybe somewhat mystical valley floor of the Justistal opens up with a view of the Hindersberg alp hut, and, right at the rear of the valley, the Sichel, a crescent-shaped pass crossing to the west of the Sieben Hengste to Eriz in the Zulgtal valley. The return journey on this easy and remote trail leads by the same route back to the starting point.
