Visited Saluga and Ghazal or First Cataract Islands Protected Area during travel to Aswan's Nubian Monuments in early October 2022. Also "visited" another Bird Migration Route, Lake Nasser, during the visit to the Kalabsha Temple, but can't write enough about that brief passage.
Saluga and Ghazal are not actually two Nile islands, but a cluster of twenty or more islands. The park superintendent said that in winter, or when the water level is at its lowest, more rock formations appear, revealing fish nests, sandy beaches and other geologic features.
Despite its small size (only 0.5 sq.km) and location next to a very urbanized Aswan City, this property manages to maintain its natural values. During my visit, the place is filled with sounds of birds and water hitting rocks.
