Nature-based tourism is increasingly encouraged to support local socioeconomic development in and around protected areas, but managing protected areas for tourism could challenge existing park uses associated with self-organized outdoor recreation and local resource use. We used a web-based Public Participatory Geographic Information System (PPGIS) to identify the most important places and values of local, domestic, and international visitors to Jotunheimen National Park and Utladalen Protected Landscape in Norway. Scenic and recreation values were prioritized by all groups, but local users mapped more values relating to hunting, fishing, gathering and cultural identity. While the three user groups overlapped in some places, we found that they self-segregated to some extent. Our study affirms the importance of spatially explicit analyses to support protected area management. Understanding the spatial distribution of values held by different user groups can aid in designing tourism management strategies that minimize intergroup conflict.
