"Located outside Oudtshoorn in the Western Cape, the Cango Caves are famed for spectacular, almost otherworldly speleothems and offer two tour options—the 60-minute Heritage Tour (R110) and the 90-minute Adventure Tour (R165); daily visitor numbers are limited to preserve the caves so booking in advance is essential, and due to cramped, tight spaces pregnant visitors or those with claustrophobia, high blood pressure or muscular ailments are advised not to visit." - SilverKris
