Heritage is a very complex concept that is characterized by having multiple meanings. Despite this, there is no doubt as to its attraction for carrying out tourist activities. In the specific case of cultural heritage, there is widespread agreement in considering it as a tourist resource given the interest it raises amongst visitors of all origins. This is not, however, always the case and it can be observed that in certain areas, especially rural ones, certain limitations exist. They are caused by multiple factors such as the importance of the resource itself, although the distance to the main centers of tourist attraction is also considered a key point. Due to this, the study puts forward the need for joining forces and attractions in order to create tourist itineraries based on a peculiar kind of resource: Historical Ensembles. In order to achieve this aim, we used the network analysis tools included in a geographical information system and applied it to a rural context, which was that of Extremadura in Spain. To be precise, the closest facility and service area tools were used. The results of the various analyses reflect the real possibility of generating tourist itineraries as a first step in the design of tourist products. In this way, the administration can be provided with a management tool capable of laying the foundations of a coherent and efficient tourist policy.
