About Tejo International Natural Park

Tejo International Natural Park is Iberia’s largest cross-border protected area, celebrated for its rich biodiversity, dramatic river landscapes, and harmonious coexistence of traditional rural life and nature across the Portugal-Spain border.

Wilderness Landscape & Natural Heritage

Spanning approximately 350,000 hectares along the Tagus River, Tejo International Natural Park (Parque Natural del Tajo Internacional in Spain and Parque Natural do Tejo Internacional in Portugal) forms a unique transboundary conservation area between eastern Portugal and western Spain. Established in 2008, it protects a mosaic of Mediterranean and Atlantic ecosystems that include river valleys, cliffs, cork oak forests, montado oak woodlands, and riparian wetlands. The park’s rugged geology is marked by steep cliffs, deep river gorges, and vast forests inhabited by iconic Iberian wildlife such as the endangered Iberian lynx, Spanish imperial eagle, black stork, and otters. This landscape supports diverse flora, from cork and holm oaks to aromatic shrubs and wildflowers, contributing to a region rich in ecological value and biodiversity. Historically, the area is known for its agricultural traditions, including extensive cork harvesting and sheep grazing, which remain part of the cultural fabric today. Outdoor enthusiasts are drawn to the park for hiking, birdwatching, canoeing along the Tagus River, and exploring the serene countryside dotted with picturesque villages such as Castelo Branco and Alcántara. The park also features historical landmarks like the Alcántara Roman Bridge – a monumental engineering feat spanning the Tagus River since the 2nd century AD. Tejo International Natural Park offers visitors a tranquil escape into nature, blending impressive natural scenery with cultural heritage and outstanding opportunities for wildlife observation in an internationally cooperative conservation setting.
