Principles of a mobile gps-enabled gis acting as a tourist infor­mation sys­tem are discussed and exemplified with special focus on the narrative aspects of tourist guidance. Flexible adaptation to user movements is accomplished by providing information about objects that the user passes as well as site-specific ‘narrative links' to new locations that the user may choose to visit. The strategy is expected to enable an enhanced travel experience for someone heading for a specific destination while still provide the basis for 'explo­rative detours'. The principles are illustrated through a case-study of H.C. Andersen's residences in Copen­hagen
