This chapter aims to provide in-depth knowledge of how nature-based tourism destinations could expand and develop sustainability through shadow destinations. The analysis uses two case studies from central Sweden to show how shadow destinations could contribute to a more sustainable tourism development. Interviews were conducted with different stakeholders, such as destination marketing organizations, tourism companies and public actors. The results show that a shadow destination can be developed along with the main destination by networking with the destination marketing organization. This study’s practical implications indicate that a shadow destination should work with the main tourist attractions or destinations to expand the tourists’ perception of the ‘destination’.
