Hiking consists of spreading trails throughout a territory, which results in a reconfiguration of the territory. Trails are pedestrian routes created in a territory and are intended to guide walkers in an autonomous and self-guided way, by marking, signposting and linking points and places of interest. Several authors state that hiking tourism is closely linked to a healthy lifestyle and contact with nature and is “environmentally friendly” tourism. The theme chosen for this work was the routes and trails in the city of Valongo. The aim of this work is to understand the perceptions of the Valongo trails and routes and their experience in this context. Methodologically, through a questionnaire survey, we sought to analyse the perceptions of visitors who take walks/trails in the municipality of Valongo. A total of 145 questionnaires were collected and analysed after validation. As the main results of this research, the vast majority considered walking routes to be an asset for both visitors and residents, and a very positive experience. In addition, the sample provided a number of useful recommendations in terms of safety and promotion.
