Cycle along the old railroad Treungbanen. A perfect trip for the whole family.
You can start at the Touristinformation in Treungen, where you can also rent bycycles. The touristinformation is open at the middle of june till the midle of august.
Enjoy the trip in a beautiful, cultural landskape. If you want, you can cycle all the way to Åmli in Aust-Agder. But then you'll have to cycle on the Rv11 at times.
