The Cango caves - this 4500-million-year-old cave of stalactites and stalagmites will astound you

TThe Cango Caves even has its own pieta, created long before Michelangelo’s Madonna and Child. There is also the Pulpit of the Cathedral, a formation that looks like the foot of a staircase. Yet another Christian reference is named Lot's Chamber, which looks like the biblical Lot and his family carved in stalagmites.

If you’re up for more adventure, the Adventure Tour starts at the end of these caves. On this tour, you’ll climb Jacob’s Ladder, crawl through a very long tunnel and climb through a hole. Beware, this is not for kids under six, people who have high blood pressure, or for the claustrophobic.

For your outing, dress practically in comfortable shoes and for hot and humid conditions. Tread lightly—it is an absolute privilege to be in such an environment. Tours are in English, but Afrikaans, German, French and other language guides may be available. Call in advance for information.
