Charterhouse Cave, Limestone cave in Mendip Hills, Somerset, England
Charterhouse Cave is a limestone cavern system in the Mendip Hills that spreads deep underground with multiple spacious chambers connected by passages. The site features flowing underground streams that have shaped the rock formations over time.
The cave entrance was first explored by researchers from the University of Bristol in 1939, marking the beginning of modern investigation. Subsequent exploration campaigns over the following decades revealed the full extent of the underground system.
The cave holds scientific value for researchers studying geological formations, with analyses revealing specific trace elements like Magnesium, Strontium, and Barium in the Great Chamber.
Entry to the cave requires permission and is only suitable for experienced cavers who are properly equipped and physically prepared. You should expect steep climbs, narrow passages, and challenging conditions throughout your visit.
The underground streams that flow through the cave eventually connect with water systems elsewhere and surface in nearby gorges. This hidden network of flowing water shows how the landscape beneath the hills is all interconnected.
