The CETS is an initiative that aims to promote the development of tourism in sustainability. CETS is a voluntary method and commitment to apply the principles of sustainable tourism, guiding the managers of the territories that are committed to sustainability and companies to define their strategies in a participated manner.
Today, there are 102 spaces attached to CETS, distributed in 15 countries, while in Spain there are 29 protected natural spaces (ENP) in which 400 companies are attached. Among the benefits of this accreditation, the distinction in Europe is as a territory of excellence in sustainable tourism, the impulse to a balanced socioeconomic development and the development of quality tourism products, authentic and consistent with its environment.
Urdaibai was declared a Biosphere Reserve by UNESCO in 1984, at the proposal of the Basque Government, after an intense social movement to preserve its high environmental value and become a territory for reference sustainability. The Oka River and its marshes are its nerve center and constitute a landscape of great environmental value. This territory of 22,000 hectares, ranging from Matxitxako to Punta Arboliz and with the southern border in Oiz, inhabit approximately 45,000 people, distributed in 22 municipalities, full of history, culture, gastronomy and natural heritage.
