Al-Azhar Park is an 80-acre public park built in 2005 on the site of a centuries-old rubble mound along the eastern edge of Islamic Cairo. It was funded by the Aga Khan Trust for Culture and is one of the few large green spaces in central Cairo — a fact that makes it enormously popular with families on weekends and a genuine haven on weekdays.
The park's main attraction for visitors is the view: the eastern wall of Islamic Cairo, with its restored Ayyubid fortifications, runs along one edge, and the park itself sits on elevated ground that gives panoramic views over the domes and minarets of Islamic Cairo to the west. There are cafés and restaurants within the park, including one in a historic restored building. The sunset view from the hilltop terrace is one of the best in the city.
Entry requires a ticket; the park is open daily. It's a good place to recover after hours in the heat and bustle of the bazaars next door.
