The Illgau - St. Karl cable car, which is in the middle of the village, takes you to the starting point, the Oberberg St. Karl mountain station.
After a short run, you reach the cosy Oberberg mountain restaurant. From here it's 100m along the road to the alp building. Now the trail climbs steeply for a short while to the picturesque Baumkragen. Pass the alp Unterer Chaltenbrunnen and follow the hiking trail towards Strit - Hinter Oberberg. You cross the Rieter with its meagre meadows, flowers and almost a dozen "Euschen". Until the last quarter of the 20th century, these were used for the temporary storage of mountain hay, which was only brought to the winter stables of the cattle with sledges, the "Männeln". The trail climbs gently through bush and forest to Zopf, point 1330, where a bench at the signpost invites you to take a short break. The Kaiserstock with its vassals, the Fronalpstock and its grassy mountains, in the continuation towards the west the lake, the Pilatus and the Rigi mountains. This magnificent arena must be observed. Continue downhill to the Hinterer Oberberg with its charming terraces and scattered farms. On the right of the Zingelberg is the Herz Jesu Chapel. At Bergli, follow the ancient church path to the left through the Linthi forest. Past the old "Gruebeli", which serves as a shelter for tired hikers, we approach the starting point, the village of Illgau.
