Tourist Guides are representatives of the cities, regions and countries for which they are qualified. It depends largely on them if visitors feel welcome, want to stay longer or decide to come back. They therefore contribute considerably to the perception of the destination. Tourist Guides are able to help travellers understand the culture of the region visited and the way of life of its inhabitants. They have a particular role on the one hand to promote the cultural and natural heritage whilst on the other hand to help ensure its sustainability by making visitors aware of its importance and vulnerability.
