Alhambra de Granada
Good to know:
The Alhambra is open every day of the year with the exception of December 25 and January 1. There are day and evening visits available. Admission per adult is 14 euros. Your ticket will have a specific time slot for you to enter the Nasrid Palace. The whole tour of the grounds took me four to five hours. Important: Book your ticket well in advance! I planned on booking two weeks in advance - and all tickets via the official website were already sold out. Instead, I purchased a Granada Card that also gives entrance into the Alhambra.
