The Autonomous Community of Navarra (Nafarroa in Basque), with its capital Pamplona, covers an area of 10,932 km2 and has a population of 640,000 inhabitants, of which around 200,000 live in the capital. Navarra is made up of three major regions: the Navarran Pyrenees, the Central Zone and the Riverside Zone, with different bioclimatic features. Located in the north, the Navarran Pyrenees is the green area par excellence. The high peaks of the east, in Belagua and Roncal, soften as they stretch out through Aezkoa, Baztan, and the Region of Bidasoa towards the Cantabrian Sea. At the foot of the Pyrenees sits Pamplona, a green, walled city. Large and beautiful parks and gardens surround its old part, which is very well preserved and practically all pedestrianized. Pamplona boasts its exuberant Fiestas de San Fermín. In the transition towards the south, the Central Zone is synonymous with history. Village-forts, walls, castles and palaces emerge triumphantly among the rolling hills, vineyards and cereal crops that characterise this territory. La Ribera is lively and open. A territory of flatlands with aspen, willow and poplar groves and the spectacular Natural Park of Las Bardenas Reales, a semi-desert with an almost lunar-like appearance, characterised by flatlands, ridges and ravines. Tudela, the capital of La Ribera, was founded by Arabs in the 9th century. Navarra is also pilgrim territory: for centuries the faithful have used the pass at Roncesvalles to cross from France on their way to Santiago.
