International Douro Natural Park

International Douro Natural Park is one of the largest protected areas in Portugal, stretching along the valley of the Douro River, which here forms the border between Portugal and Spain. On the Spanish side the same landscape is known as Arribes del Duero, and the village of Masueco de la Ribera in Salamanca province makes a good base for exploring it.

What is the International Douro Natural Park?

The park covers about 868 km2 (335 sq mi) in northeast Portugal. It lies within the municipalities of Miranda do Douro, Mogadouro, Freixo de Espada à Cinta and Figueira de Castelo Rodrigo, running as a long strip along the frontier. It also takes in the border stretch of the Águeda River. It was established to safeguard the region's scenic landscape along with its wildlife and plants.

What can you see around Masueco?

The defining feature is a set of deep, rocky gorges carved by the Douro. Around Masueco, visitors head for the viewpoints, and one of the most frequently mentioned is Pozo de los Humos, overlooking the Pinero waterfall as it drops into the canyon. Nearby Pereña de la Ribera has waterfalls too. Hiking trails on both sides of the border link a string of lookouts, and boat trips on the river leave from places such as Aldeadávila de la Ribera and Vilvestre. On the Portuguese side, São João das Arribas and Cruzinha are popular miradouros.

Which animals live here?

The steep cliff faces make ideal nesting ground for birds of prey. Species reported in the region include golden eagle, peregrine falcon, eagle owl and griffon vulture, and both white and black storks breed here. Among mammals the wolf is the headline species, and otters live in the river.

What is the vegetation like?

The mild, Mediterranean-type microclimate of the canyons supports a rich plant life. Holm oak, cork oak, Pyrenean oak and olive trees grow here. The terraced slopes are planted with vines, almonds and olives, giving the landscape its distinctive farmed look.

When to go and how to plan

Spring and early autumn are good for walking and birdwatching, when slopes are green or golden and temperatures are manageable. Summer can be very hot in the valley, so schedule walks for the morning. Bring sturdy shoes, water and binoculars. Before you travel, check current access rules and boat-trip schedules with local operators or the park authorities.
