The caves are naturally formed by water erosion through the limestone rock.The calcium-rich water that runs through the caves have formed the unusual stalactites and stalagmites formations. Travel through the caves is by tram, at certain points during the tour visitors are allowed to alight from the tram and get close up to the formations.One main area of the caves is a huge cavern, termed "The Great Hall", measuring over 100 feet in height. After the Great Hall the tram stops at "The Village". At The Village some of the formations have joined together to form columns after thousands of years. Harrison's Cave is in the central uplands of Barbados. It is situated at 700ft above sea level.
