Visitors can join one of the six daily guided tours to see the impressive stalactites, stalagmites, helictites and flowstone of this spectacular cave.
Descend the entrance steps and dramatic LED lighting gradually exposes thin, curtain-like shawls and the cave's largest speleothem, the Wedding Cake.
The walking trail along the cave floor reveals even more deposits of calcite and carbonate as they appear to flow through the cavern.
It's hard to believe this subterranean fairyland is concealed beneath the potato crops and hop fields which thrive in the red basalt soil of Gunns Plains.
Take a picnic and enjoy the view above ground as well the delights deep below.
