Located in southwestern Spain, Cádiz is one of the country's most underrated and yet phenomenal travel destinations. As one of the oldest inhabited cities in Europe, travelers can expect many historic attractions, from the Torre Tavira watchtower to the grandiose Cádiz Cathedral. You can also explore several beautiful outdoor spaces including Genovés Park and the laid-back beaches of La Victoria and La Caleta. When you want to wind down, Plaza de España and Plaza de San Juan de Dios are excellent places to people-watch.
