SUMMARY
This paper demonstrates that different assessments of the tourism attributes of a destination exist according to whether the perception of those tourists visiting that destination is that it is sustainable or whether, on the contrary, they perceive that it shows problems of unsustainability. Consequently, for a destination to be able to advance in terms of sustainability, it is not enough just to implement supply policies, but it is also necessary that its tourists are involved in this process as well; that is, demand policies must be developed that ensure a greater awareness and responsibility of tourists in the destinations they visit.
