It lies about 7 km south of Table Mountain, on the southern side of Constantia Nek.

The range, made up of resistant sandstones of the Table Mountain Group, dominates the southern suburbs of the city on the verge of the Cape Flats.

The lower eastern slopes of Constantiaberg are covered by the commercial pine and gum plantations of Tokai forest, and are crisscrossed with hiking trails and gravel roads that are used for harvesting the trees.

It was constructed in the 1960s and is used to transmit signals for many local television and radio channels, and also to support cellular networks.

Elephant's Eye cave, a popular hiking destination, is the mountain's biggest feature after the mast.
