Backpackers are an unusual category of travellers. Their unique mobility patterns, spatial practices, and the areas they travel through expose them to health situations that remain largely unexplored to date. This article conducts a narrative literature review (across six different databases in English and French) in this domain and highlights key contributions. The results show that backpackers frequently experience health problems during their trips. They are described as being more at risk than other tourists and more inclined to adopt harmful behaviours. However, the majority of related studies lack contextualisation, which is an advantage of geographical analysis. Moreover, given the limited volume of the existing literature, this review serves as an invitation to geographers to delve deeper into this intriguing field.
