This is one of the main symbols of Granada and one of the most amazing Arab citadel in the world. If you are not joining us in this social activity on Friday night, do not hesitate to visit the palace on your own; it is really worth visiting. But do not forget to book the tickets in advance (at least some weeks before). Visiting the Alhambra early in the morning and not on the weekend is advisable: http://apc.ticketmaster.es/nav/es/mucho_mas/granada/alhambra_y_generalife_09oz/alhambra_general/entradas.html?canalMB=ALH&utm_campaign=ALH-weboficial&utm_source=alhambra-tickets.es&utm_medium=link&canalMB=ALH
This charming Muslim neighborhood was declared by UNESCO Word Cultural Heritage in 1994. Its architecture brings to mind the Arab style, but also other ancient Mediterranean towns. The best way to visit Albayzin is just by wandering through its narrow streets, which leads to beautiful viewpoints (miradores), such as Mirador of San Nicolás. Hammams (Arab sauna & baths) were spread all over this area and still nowadays you can enjoy a traditional bath in one of the oldest hammams left in Spain (for more info look here or email to firstname.lastname@example.org)
This neighborhood is known for its houses on caves and the amazing views of the city. You can enjoy with the zambras, the typical flamenco dance inside the caves. For more information about traditional flamenco in a cave or flamenco & dinner look here or email to email@example.com. General info at: http://www.granadaesflamenco.com/festivales-y-ciclos
