The Mont-Aux-Sources is part of a basalt plateau which lies at an average elevation of about 3,050 meters (10 000 ft).

[1] The highest point is a peak 3 km from the Drakensberg escarpment, attaining an altitude of 3,282 metres (10,768 ft).

Several rivers originate in the Mont-Aux-Sources, foremost of which is the Tugela, which flows eastwards into the Indian Ocean on the KwaZulu-Natal coast.

Some 7 km from the Mont-Aux-Sources, the Tugela plunges 947 m in a series of falls in the Royal Natal National Park.

[3] Another important river is the Elands, named the Namahadi in its uppermost section in the area of the Fika-Patso Dam.
