Castilla y León is Spain’s largest autonomous community, covering a vast area of mountains, high plains, forests and river valleys. Formed from the historic kingdoms of Castilla la Vieja and León, it is a region where remarkable cultural heritage sits alongside some of the most important wildlife habitats in northern and central Spain.
The region’s history is impossible to miss, from ancient Roman remains and medieval castles to some of Spain’s finest historic cities. But beyond its towns and monuments, Castilla y León opens out into an enormous landscape of mountains, forests, grasslands and river gorges, where some of Spain’s most interesting wildlife can still be found.
Among the region’s historic cities, Segovia is particularly famous for its Roman aqueduct, an extraordinary feat of engineering built from enormous blocks of stone without mortar. The aqueduct remains one of the city’s defining landmarks and is a reminder of the many layers of history found throughout Castilla y León.
But Castilla y León is far more than its historic cities and monuments. Beyond the towns, the region unfolds into rolling plains, rugged mountains, forests, river valleys and deep gorges. These varied landscapes support an impressive range of wildlife and make Castilla y León a rewarding destination for walking and nature-based travel.
Going back much further in time, the archaeological sites of Atapuerca, near Burgos, contain some of the most important prehistoric discoveries in Europe. Fossils and stone tools found here provide evidence of early human occupation dating back hundreds of thousands of years, adding another fascinating layer to Castilla y León’s remarkable history.

The landscapes and Natural Parks of Castilla y León
Beyond its historic cities and towns, Castilla y León is dominated by an enormous high plateau surrounded by mountain ranges. The Cantabrian Mountains lie to the north, the Sistema Central forms much of the southern boundary, and the Sistema Ibérico rises to the north-east. Towards the west, the landscape opens towards Portugal.
This combination of high plains, mountain ranges, river valleys and deep gorges creates a remarkable variety of habitats. The Duero is the region’s major river, rising in the province of Soria before flowing westwards across Castilla y León and eventually forming part of the Spanish-Portuguese border. Together, these landscapes help explain the region’s importance for wildlife and make it particularly interesting for walkers and nature enthusiasts.
1 Lago de Sanabria The Lago de Sanabria y Sierras Segundera y de Porto Natural Park protects Spain’s largest natural glacial lake together with the surrounding mountains, valleys and forests in the province of Zamora. The combination of high-altitude landscapes, waterways and woodland makes the park an excellent area for walking and exploring the natural environment.
2 National Park of the Picos de Europa Now one of Spain’s best-known mountain parks, Picos de Europa extends across the Cantabrian Mountains and includes spectacular limestone peaks, deep valleys and river gorges. The Cares River canyon is one of its most dramatic features, while the high mountain landscapes provide habitat for a wide range of wildlife.
3 Montaña Palentina Natural park In the north of Palencia province, Montaña Palentina is an important area of mountains, forests and high-altitude habitats. It is particularly significant for wildlife, including the endangered Cantabrian brown bear, while its extensive juniper woodland adds to the botanical interest of the area.
4 Cañon del Rio Lobos This spectacular limestone canyon straddles the provinces of Soria and Burgos and is one of the region’s most distinctive landscapes. Among its best-known landmarks is the Romanesque hermitage of San Bartolomé, built in the early 13th century beneath the cliffs of the canyon.
5 Hoces del Rio Riaza The Riaza River has carved a dramatic landscape of limestone gorges, cliffs and ravines through the Segovian countryside. The combination of river valleys and rocky cliffs also makes the park an important habitat for birds of prey and an interesting destination for walking and wildlife watching.
6 Hoces del Rio Duraton Following around 27 kilometres of the Duratón River, this protected area is characterised by deep limestone gorges, some rising to around 100 metres above the river. The cliffs and river landscape provide important habitat for birds and make the park particularly rewarding to explore on foot.
7 Sierra de Gredos Regional Park The Sierra de Gredos forms part of the Sistema Central and is one of the best areas in Spain for seeing the Gredos ibex (Capra pyrenaica victoriae). This distinctive subspecies of Spanish ibex is adapted to the rugged mountain environment, while the higher parts of the range offer some excellent walking landscapes.
8 Las Batuecas y Francia Natural Park This mountainous area in Salamanca province combines forests, valleys and dramatic scenery with an unusually rich cultural heritage. The surrounding landscape contains cave paintings, Roman mining remains, hermitages and monasteries, while several villages are recognised for their historic and architectural importance.
9 Arribes del Duero Natural Park Along the western edge of Castilla y León, the Duero has carved enormous gorges through the landscape before forming part of the border between Spain and Portugal. The steep cliffs, river valleys and surrounding countryside create an important refuge for wildlife and one of the most spectacular landscapes in the region.
El Bierzo and the mountains of León
El Bierzo is a historic comarca in the province of León, centred on Ponferrada and surrounded by mountains. The area is known for its varied landscapes, from fertile valleys and vineyards to wooded hills and higher mountain terrain. It is an excellent example of the diversity found across Castilla y León and makes an interesting base for exploring the western part of the region.
