Even the ancient inhabitants of pile-dwellings chose Erlach on Lake Biel and St. Peter's Island as their abodes. The Romans too left traces. Bishops and members of the nobility ruled from here in the Middle Ages. Today both are popular destinations for nature lovers and visitors seeking rest and relaxation.
This leg of the journey covers 64 kilometers from Laupen on secret paths over the wild Längenberg Mountain up to Thun.
The nostalgic expedition starts in Laupen near the train station and leads on the former railroad route up to the turning point near the Gümmenen Train Station.
Laupen Castle towers high above the medieval town of the same name at the confluence of the rivers Sense and Sarine. The splendid fortress is the emblem of the region, and a protected monument of national importance.
