Situated in the foothills of the majestic Swartberg Mountains, the Cango Caves comprise a series of caverns extending 5 km into the mountain. A 1.2km stretch is open to visitors. Originally discovered by hunter-gatherers almost 80,000 years ago and opened to the public in 1891, the caves are one of the oldest show-caves in the world. The Standard Tour lasts 60 minutes and extends as far as the sixth chamber.

For the more adventurous, the 90-minute Adventure Tour escorts visitors through a series of small and challenging tunnels culminating in the awesome but aptly named Letterbox. Experienced and multilingual guides conduct both options. Comfortable footwear and light clothing are advised. The modern administration complex includes a family restaurant, coffee-shop and bar, curio shop, and Interpretive Centre. In the Auditorium, Cangos 2, 3 and 4 (the 3,8 km not open to the public) may be viewed.
