The Garden of the Island (Jardín de la Isla) occupies a tongue of land in the Tagus formed by an artificial channel, and is the oldest of Aranjuez's royal gardens. It was first developed under Philip II in the 16th century and retains a more intimate, shaded character than the vast Jardín del Príncipe. A long avenue of fountains dedicated to mythological figures runs its length, and the surrounding plane trees and willows create deep shade even in midsummer.
The garden is free to enter and tends to attract fewer visitors than the main Parterre alongside the palace. It's an excellent place to escape the midday heat and to see some fine 18th-century fountain sculpture. The river views from the garden's southern edge are among the most pleasant in Aranjuez.
