The 370 km of GR - 33 Grande Rota do Zêzere's extension runs through 13 counties and joins important national brands: Serra da Estrela, Aldeias do Xisto, Castelo de Bode and Rio Tejo. The route is designed to be multimodal, and can be done on foot, by bicycle or by canoe. Thus, it can be done in a continuous and chained way, by sections or even in multimodal circuits, using more than one discipline. The innovative character of the 13 Intermodal Stations along the route, where users can, for example, exchange a bicycle for a canoe, contributes to this.
