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.
Lake Biel/Bienne in the Jura & Three-Lakes area of Switzerland is situated on the border between the French and German speaking parts. It borders the southern edge of the Jura, where the slopes are used for intensive cultivation of vines.
