Sudwala Caves

Sudwala Caves is a dolomite rock cavern system that is estimated to have been formed about 240 million years ago. It One-hour tours of the cave are run during the day, and a monthly five-hour-long Crystal Tour takes visitors 2000 metres through the cave, with the tour culminating at a chamber that bears aragonite crystals and the Sudwala Star.
