The main aim of the project was to initiate a process to set guidelines for sustainable tourism destinations and to help regions overcome current social, economic and environmental constraints through the exploration and adoption of relevant policies and good practice. Achievements: A regional SWOT analysis of sustainable tourism has been carried out in all partner regions. The CREST work has been developed from the viewpoint of the destinations, based on the principle of local planners working together with local residents. While each destination has different priorities, all of them share a number of common problems, such as the huge influx of visitors during a relatively short summer season and the consequent seasonal infrastructure overload. All of the partners involved are close to, or within, areas of natural beauty, which can easily be damaged by over use and exploitation.For a destination to be sustainable, other basic issues had to be dealt with, such as the provision of affordable housing for local people, the creation of job opportunities all the year round and the encouragement of young people to stay.The main outcome of the project was the “CREST Toolkit with Recommended Actions for Creating a Sustainable Tourism Destination”, illustrating the results of the project and good practise examples.
