Is located 100m north east of the locked gate on the Pagoda Track and 700m north east of the Glowworm Tunnel, Newnes Plateau. This 85m long overhang has a dry elevated floor and its southern extremity features an almost spherical cavern. In the centre is a small string waterfall that drops down from a slotted keyhole in the domed roof. Quite by accident, it was discovered that this is a whispering wall, so a quietly spoken comment at one end can be clearly heard at the other. Named by Michael Keats and Brian Fox on a Bush Club walk, 2nd January 2017.
