Three Counties System

The Three Counties System consists of interconnected limestone caves spanning 89 kilometers across Cumbria, Lancashire, and North Yorkshire regions.

The concept of linking separate cave networks into one system emerged in 1968, with the final connection established in 2011 through extensive exploration.

The system incorporates distinct passages with names reflecting local folklore, including Bull Pot of the Witches and Lancaster Hole beneath Barbon Low Fell.

Cave exploration requires professional guidance and specialized equipment, as the complex network contains over 40 entrances leading to various underground passages.

The underground streams flow through three different counties, allowing cavers to enter in Yorkshire, traverse beneath Lancashire, and exit in Cumbria.
