You need to be at the Nasrid Palace entrance at the time indicated on your ticket.
The Alhambra opens 08;30 , so you can enter anytime that day, just be at the Nasrid Palace on time not ish as if your late your you will loose the slot (14;30 would be good )Edited: 09 November 2018, 06:02
I recommend you enter Alhambra "at least" 1 hour before your Nasrid time of 3pm. You could enter several hours before, all depends whether you wish to do the other sections of Alhambra before or after Nasrid.
An overall visit tends to takes between 3 hours (rushed) up to maybe 5 hours. Within that timeframe, Nasrid takes nearly an hour.
Thank you all so much. Will probably head there around 11....
want to spend a long time there... is there a place to eat there? Seating area if we brought sandwiches?
