Most of the tourist sights in Seville are in the central area, which is flat and best explored on foot. Those travelling further afield will find buses the easiest and most economical way of getting around. Bus stops are easy to find on the main avenues and run on circular routes around the city, and line routes in all directions out of it. Bus routes emanate from Plaza Nueva, Plaza de la Encarnacion, La Barqueta, and Prado de San Sebastian.Taxis can be found at designated stands in all the main plazas, or can be hailed on the street if showing a green light, which means they are available. Tourists should always ensure that the meters in taxis are operational and that they are only turned on at the beginning of their trip as foreigners are sometimes the victims of overcharging.As with all Spanish cities, it is best to avoid driving in Seville as the roads are confusing and hard to negotiate. Spanish drivers are renowned for their casual and chaotic approach to rules of the road, and although rented cars are wonderful for excursions out of Seville, they are best kept parked at the hotel while sightseeing in the city. Those exploring the city on foot should be sure to get a map when wandering around neighbourhoods like Santa Cruz, as the narrow maze of streets can be rather confusing.
