The afternoon Alhambra slot cuts the crowds, not the price
The Alhambra's general admission ticket is a fixed €22.27 whether you book morning or afternoon — pricing does not vary by time slot. What does change is availability: the 14:00 onward window is typically easier to book at short notice (2 to 3 weeks ahead versus 2 to 3 months for popular morning slots in peak season). The light inside the Nasrid Palaces in the afternoon comes strong from the west, different from but not worse than the morning. The crowds also thin slightly after 15:00 as the morning visitors leave. Check current availability at tickets.alhambra-patronato.es before booking.
