9. Cango Caves Oudtshoorn
The Cango Caves Oudtshoorn is located in the foothills of the Swartberg range. It is just near the Western Cape Province. It is one of the most beautiful tourist caves in the world and attracts millions of visitors yearly. And although this extensive system of tunnels is more than four kilometers long, only a quarter of it is open for tourists who can only visit the site through an organized tour guide.
