Vanishing Falls is a ledge waterfall in south-west Tasmania, Australia that drains into a sinkhole. It is located on the Salisbury River within the Southwest National Park.
At Vanishing Falls, the Salisbury River flows over a dolerite plateau underlain by limestone. The river flows over the edge of the dolerite sill and drains straight into a cave system in the limestone, a phenomenon attributed to karst processes. The above-ground channel downstream of the plunge pool flows only during floods.[2]
The Salisbury River is a tributary of the New River.[1]
The falls are surrounded by dense scrub and are located in remote wilderness, accordingly there are no designated trails leading to the falls.[3] [4]
