Tajo International Natural Park is a unique transboundary protected area straddling Spain and Portugal, offering diverse ecosystems along the Tagus River and rich opportunities for hiking, wildlife viewing, and cultural exploration.
Tajo International Natural Park, established in 2008, is a remarkable example of cross-border cooperation for nature conservation, spanning approximately 35,000 hectares along the Tagus River across the autonomous community of Castilla-La Mancha in Spain and the Alentejo region of Portugal. This park protects a rugged and varied landscape characterized by deep river canyons, extensive Mediterranean forests dominated by cork oak and holm oak, and important riparian zones that provide critical habitat for numerous species. The Tagus River, the longest river on the Iberian Peninsula, is the park’s defining geographical feature, creating spectacular cliffs and pristine waters that support a rich biodiversity, including rare birds of prey such as the Iberian imperial eagle and the black stork.
Historically, the area holds cultural significance with traces of ancient settlements and traditional agricultural practices still evident. Visitors are drawn to the park for its excellent hiking and mountain biking trails with scenic overlooks of the river gorge, as well as opportunities for canoeing and kayaking along calm stretches of the Tagus. The park’s sparse population and relatively low tourism make it a haven for bird watchers and those seeking tranquility in natural surroundings. Notable landmarks include the historic Alméndro Tower in Spain and the dramatic cliffs near Castelo de Almourol in Portugal. The park’s management promotes sustainable tourism, balancing preservation with regional economic development through ecotourism initiatives and environmental education.
