There are lots of gardens, with lots to see. Including views of the rest of the Alhambra.
The gardens have a variety of decorative plants and water features plus extensive food growing areas such as orchards. It was a long day with lots of walking, much of it in the rain. But we made it despite my bum knee. One kid was not so lucky. He slipped and fell in one of the fountains.
The top right photo is of the water stairs, so called because water runs down the center of the handrails on either side.
This “green” roof is between the Generalife and the paths that access the rest of the Alhambra. It takes a while to walk from point to point, so factor that into your schedule. Our timeslot for the Nazrid Palaces was at 1:30PM so we went to the Generalife first, followed by the alcazaba and museum, then the palaces.
