The hiking tour from Magglingen across Mt. Twannberg down to Twann is a "classic-" - the most popular tour of Lake Biel. The beautiful views of Twannberg mountain contrast strikingly with the deep Twannbach ravine. The views of the lake and Petersinsel island round off the tour, cementing its effect as a unique hiking experience. A subsequent stroll through the center of Twann, which is well worth seeing, is followed by a bonus - a comfortable cruise on a ship back to Biel.
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.
