Haderslev features a compact city center that is conducive to walking, allowing travelers to easily access shops, cafes, and historic sites like Haderslev Cathedral. The charm of the old town makes strolling a pleasant experience. However, for those staying outside the central area, a walk might involve longer distances. Residential neighborhoods further from the core are not as pedestrian-friendly, thus limiting the overall walkability for travelers seeking convenience in exploration.

Public transport in Haderslev consists mainly of buses, offering connectivity within the town and to nearby cities including links via FlixBus to major urban areas like Copenhagen and Aarhus. While this makes travel accessible, the frequency and reach of these services are less robust compared to bigger cities, presenting challenges for travelers who might want to depend solely on public transit. For infrequent travel needs or exploring beyond major routes, planning around the bus schedule will be necessary.

Haderslev benefits from Denmark's overall bike-friendly culture and infrastructure, making cycling a practical and enjoyable mode of transport. The city and its surroundings are mostly flat, providing an ideal terrain for biking. With accessible bike rentals and dedicated cycling paths, travelers can navigate the city and tour the scenic areas with ease. Biking serves as a convenient, eco-friendly option for exploring both the urban landscapes and nearby natural attractions.
