Timbuktu is located on the southern edge of the Sahara 15 km (9 mi) north of the main channel of the River Niger. The town is surrounded by sand dunes and the streets are covered in sand. The port of Kabara is 8 km (5 mi) to the south of the town and is connected to an arm of the river by a 3 km (2 mi) canal. The canal had become heavily silted but in 2007 it was dredged as part of a Libyan financed project.

Like other important Medieval West African towns such as Djenné (Jenné-Jeno), Gao, and Dia, Iron Age settlements have been discovered near Timbuktu that predate the traditional foundation date of the town. Although the accumulation of thick layers of sand has thwarted archaeological excavations in the town itself, some of the surrounding landscape is deflating and exposing pottery shards on the surface. A survey of the area by Susan and Roderick McIntosh in 1984 identified several Iron Age sites along the el-Ahmar, an ancient wadi system that passes a few kilometres to the east of the modern town.
