Another good excuse to come to the Sevillian capital are the festivals. The celebrations of Easter Week and Feria de Abril (the April Fair), which have been declared of National Tourist Interest, reflect the devotion and folklore of the people of Seville, always open and friendly to visitors. But Seville's appeal does not end there, as the city is also the starting point for the many cultural routes the province offers, such as the Roman Bética Route or the Washington Irving route. The visitor will also discover the immense natural wealth of this region, which sits halfway between two continents, in natural treasures such as the Doñana Nature Reserve, declared a World Heritage Site and Biosphere Reserve by UNESCO, and the Sierra Norte Nature Reserve. They will be the ideal setting for practising outdoor sports, including hiking, horse riding, and cycling routes. If, on the other hand, golf is your sport of choice, then you will be glad to know that Seville has four excellent golf courses in its vicinity.
