Continual exploration in all the world’s major caves make the list of longest caves a continually changing rota. While Mammoth Cave in Kentucky, USA stands head and shoulders above the rest in terms of sheer length at 627.7 kilometres, other caves are constantly jostling for ranking as new discoveries extend their length.  A list of the worlds longest caves can be found at http://www.caverbob.com/wlong.htm
