Bielefeld, Germany sits along the northern edge of the Teutoburg Forest, where city paths quickly give way to ridge walks, beech woods, and wide views. Follow the Promenade from Sparrenburg Castle, head east on the Bielefeld to Oerlinghausen Walk, or roam the Dalbke and Wesser-Lutter routes for a feel of the region's wooded hills, parkland, and long-marked local trails.
