Tagus International Natural Park is a transboundary natural space straddling Portugal and Spain, renowned for its rich biodiversity and spectacular river landscapes along the Tagus River, offering unique opportunities for wildlife viewing, hiking, and cultural exploration.
Tagus International Natural Park (Parque Natural do Tejo Internacional / Parque Natural del Tajo Internacional) is a remarkable protected area spanning approximately 116,000 hectares along the border of central Portugal and western Spain. Established jointly by both nations in 2009, this park encompasses the last major free-flowing stretch of the Tagus River and protects a mosaic of cliffs, river valleys, cork oak forests, Mediterranean scrublands, and agricultural land with Mediterranean and Atlantic influences. The park is a critical habitat for endangered species such as the Iberian imperial eagle, black stork, and Eurasian otter, making it a top destination for wildlife enthusiasts and birdwatchers. Visitors can explore a variety of ecosystems supporting diverse flora including holm oak, cork oak, and holly, alongside a vibrant understory of shrubs and wildflowers. Historically, the region has been home to traditional rural communities, and the park preserves archaeological and cultural sites including medieval castles and remnants of ancient agricultural terraces. Outdoor recreation in the park centers on hiking, cycling, fishing, and river sports such as kayaking or canoeing on the Tagus River's winding course. Notable landmarks include the Senhora da Ribeira viewpoint, offering sweeping panoramas over the gorge, and the historic villages of Monsanto (Portugal) and Alcántara (Spain), which showcase Iberian heritage amid rugged nature. Offering both tranquility and adventure, the Tagus International Natural Park appeals to nature lovers, photographers, and those seeking a blend of Iberian culture and pristine natural landscapes.
