Buy 3–4 days ahead in peak season — the Nasrid slot fills first
The Dobla de Oro includes a timed entry slot for the Nasrid Palaces, the same constraint that applies to every Alhambra ticket. In June, July, and August, morning slots go within days of opening. Book at tickets.alhambra-patronato.es directly — the same slots, no markup — and choose your Nasrid time before anything else. The eight Albaicín monuments have no slot requirement.
