Call the Alhambra accessibility line before you book anything else
The accessible route at the Alhambra is not available through the standard online booking system. You need to call +34 958 027 971 to reserve it with advance notice. Do this before you buy flights — availability is limited, and knowing your visiting slot determines everything else about your trip itinerary. The accessible route covers the Nasrid Palaces ground floor and Generalife but skips the Alcazaba battlements, which require stairs.
