Abstract
The tourism sector, due to its specificities, is one area of economic activity where collaborative strategies can most contribute to increasing productivity and competitiveness. The need for immediate responses to customer interests and requirements has led companies to become more proactive, which in turn leads to the pursuit of external collaboration to develop business networks that increase business dynamism and the operational flexibility of partners. Encouraging collaboration lies in the pressures brought on by globalization and increased competitiveness, supported by the development of information and communications technologies. Collaboration promoting strategic and organizational alignments in the field of tourism is revealed to be decisive for the qualification and sustainability of destinations, promoting new markets, and facilitating synergies of larger dynamism between companies. Serra da Estrela corresponds to a medium mountain destination, classified as a UNESCO World Geopark, where the development of collaborative relationships is valued as a resource for businesses and as expanding the offer of tourist products, as well as a source of competitive advantage.
