Prepare yourself for a particularly overwhelming sightseeing experience: the Aswan High Dam is truly impressive. The Dam is 3600 metres long, 980 metres thick at base and 111 metres tall (at its highest point). The waters of Lake Nasser, the world's largest man-made lake, have amassed behind it. It provides irrigation water and electricity for the whole of Egypt. Located 13 km south of Aswan, the High Dam is usually included on south Aswan daytrips itineraries. These tours can be booked through your hotel or through any tour operator in town.
