Book Alhambra tickets at least two weeks ahead
The Alhambra sells roughly 6,600 tickets per day, spread across morning and afternoon slots. During May through October, morning slots sell out weeks in advance on the official site (alhambra-patronato.es). If you arrive without tickets, you can sometimes find same-day availability at the ticket office from 8am, but it is not reliable. The night visit (nocturna) tickets are easier to secure and give a completely different experience — Nasrid Palace rooms lit by warm light, almost empty. Worth doing even if you have a daytime ticket too.
