Go straight ahead until the end of the gardens next to the theatre, the so-called "Low Gardens of the Generalife". There is a pavilion with a checkpoint. Show your ticket to the guard and go upstairs where you will find a courtyard with a central fountain. Go through the patio and up a second staircase that takes you to the elevated "Patio of the Irrigation Ditch". Enjoy the view of the Alhambra on the left and the tranquil water fountains as you walk to the end of the courtyard.
