The paper presents the Living Lab approach for the creation of a prototype solution aimed for supporting sustainable tourism in Gorenjska region. Involving users in the process of co-creation is one of the key elements in the Living Lab approach. A Living Lab is an environment in which researchers, developers and users cooperate with the common objective of delivering a tested product, solution or service respecting the users’ requirements. The motivation is to bring together various actors in the field of tourism services development in the Gorenjska region, to create innovative solutions for supporting, promoting and encouraging development of sustainable tourism in the region and development of the region itself. The aim is to develop a web-based prototype solution that include geo location information and social networks in the Living Lab approach. The result of our research is a design of a prototype and a critical analysis of the cocreation process.
