The River Axe flows through the cave.

In 2014/2015 Cornish miners have blasted and excavated seventy metres of tunnel to allow visitors access to chamber 20.

A cavern which features a stunning Subterranean lake and breathtaking rock formations.

Experts have been left baffled by one particular fluted rock.
