New technologies are being integrated into the urban space of cities and we are progressively talking about smart cities and smart tourism. Tourism is one of the production sectors with the greatest economic impact internationally, as it directly influences cities, the provision of their services and the way people live together. It is therefore from this that the smart and sustainable tourism destination approach is conceived, influencing city dwellers and the environmental footprint of the tourism experience. In the belief that combining digital intelligence with spatial systems can improve the standard of living and raise the quality of services, the aim of the research is to explore places where the environment and the technological system are closely related, creating a greater dialogue between the various social components of these spaces, with interesting effects also in terms of relational cohesion. Spatiality is not only a physical concept, but it is linked to notions of digital geography, which we define as Phygital, in which the physical and virtual environment are combined to enhance the tourist experience. Considering the strategic axes of innovation, digitisation, accessibility and sustainability, the resulting positive impacts are distributed among economic, social and technological actors, enhancing tourist sites with improved physical and digital accessibility, and generating a competitive and inclusive type of tourism. There are many virtuous examples of STD in the world to take inspiration from, and the article takes the case study of the city of Càceres as a reference to make some reflections on smart tourism.
