Kottenforst is the broad forest west of Bonn, part of the green belt that lets the city breathe beyond its museums, ministries, and university streets. It is not a single attraction with a gate; it is a landscape of paths, old avenues, and quiet woodland.
Come here for cycling, walking, or a low-key break from the centre. The forest is especially useful if you are staying longer in Bonn and want a local outing that feels different from the Rhine promenade or the museum mile.
