This article proposes a novel method for generating context-rich knowledge about ‘hard-to-access’ places. We ground our discussion in a recent qualitative study of social settings of youth drug use in Denmark. The study confirmed that private house parties are common sites of youth drug use, although these parties presented limited opportunities for fieldwork. In response, a ‘map-task’ was introduced to the study to complement fieldwork and interviews. We assess the most significant methodological and epistemological features of this map-task, and explore how it may to used to conduct observations ‘from a distance’ in hard-to-access places. Further, we argue that the map-task has a number of analytical and logistical advantages for scholars interested in the health and social aspects of ‘hidden’ phenomena, such as youth drug use.
