Can we gain access to the experience of museum visitors? Can we describe and understand their experiences? And especially, can we grasp the physical and cognitive processes through which knowledge is constructed in museums? This article focuses on the visitor experience from an enactive perspective, i.e., that which makes sense from the point of view of visitors during their visit. An analysis of the visitor’s “course-of-experience” carried out by means of a subjective re-situ interview allows us to describe and understand the basic units of the visitors’ experiences as well as the overall experience of the visit with precision, finesse, and depth. The actions and cognitive paths of visitors, which contribute to the construction of the knowledge, are also highlighted. This approach allows us to imagine new perspectives of mediation toward visitors and thus enrich the range of experiences offered by museums.
