GB Cave

GB Cave is a limestone cave in the Mendip Hills with a main passage and branching galleries that penetrate deep into the rock. The cave features passages of varying widths and heights that create different experiences as you move through the system.

The cave was discovered in 1939 by cavers from Bristol University after ten months of careful excavation work. The breakthrough came after persistent efforts to clear away debris and reach the main passages underground.

The name GB derives from F.J. Goddard and C.C. Barker, two members of the University of Bristol Spelaeological Society who led the discovery.

Access is strictly controlled by the Charterhouse Caving Company and requires advance arrangements with the operator. The entrance gate remains locked to ensure safety and protection of the cave system.

Inside the cave lies a remarkable water-carved gorge where a stream has cut through the limestone over countless years. This passage stands out for its impressive height and width, showing the power of flowing water shaping rock.
