If you are visiting Ebeltoft, Odense or Ribe you can join one of the town crier’s walks and get a free introduction to the history of the city. In Copenhagen in the summer months you can join a New Copenhagen Tours guided walk in the city , lasting some three hours. The guides are volunteers and you decide how much you think they should get paid. Another option is to join one of the museum of Copenhagen’s free city walks, which take place every Sunday from May until September.
An alternative, non-guided tour around Copenhagen can be had if you buy a two-zone ticket and jump on bus 11 or the harbour bus . Both lines pass by several of the major landmarks and districts in Copenhagen, one by land and from the sea.
In several major cities you can also pick up free podcasts and podwalks for your smartphones and let them guide you through the town. Search the web or contact the local tourist office to see if they offer that service. Danish Architecture Centre, for example, has made a series of interesting podwalks that you can download from their website.
