The Cango Caves
are located in Precambrian limestones
at the foothills of the Swartberg
range near the town of Oudtshoorn
in the Western Cape
Province of South Africa
. The principal cave is one of the country's finest, best known and most popular tourist caves and attracts many visitors from overseas. Although the extensive system of tunnels and chambers go on for over four kilometers, only about a quarter of this is open to visitors, who may proceed into the cave only in groups supervised by a guide. The caves contain spectacular halls and grand limestone formations (on both tours) as well as some rather small passages.
