Cango Caves, Archaeological cave system in Oudtshoorn, South Africa.

Cango Caves is a show cave and archaeological site in the Swartberg Mountains near Oudtshoorn, South Africa. The connected chambers form an underground space with rock formations hanging from ceilings and rising from floors.

Stone Age paintings and artefacts show the caves were used over a long period in the Middle and Later Stone Ages. In 1780 the farmer Jacobus Van Zyl was lowered into the first chamber, a hall as long as a football field and now named Van Zyl Hall; a second chamber was found in 1792. Archaeologist A.J.H. Goodwin of the University of Cape Town dug a test excavation in 1930 and found stone artefacts and other cultural material.

The caves were used during the Middle and Later Stone Ages, and paintings and artefacts from that long occupation were found near the entrance. In 1898 Johnny van Wassenaer, the first official guide, reportedly walked 29 hours to find the end of the system. A German choir led by Günter Kallmann recorded a concert inside the caves on 26 February 1966.

Two guided tours are offered: a simpler route through larger chambers or a more demanding tour through tight passages. Those choosing the second option should be comfortable moving in confined spaces and have reasonable flexibility.

The temperature throughout the cave system remains at 18 degrees Celsius (64 degrees Fahrenheit) year-round. Some of the rock formations inside reach a height of 16 meters (52 feet).
