Three Counties System
The Three Counties System is a network of interconnecting limestone cave systems encompassing the northern English counties of Cumbria, Lancashire, and North Yorkshire. The Three Counties System is a renowned cave system that is exceedingly complicated in nature. It is the longest cave system in the UK and the twenty-seventh longest in the globe.
The Three Counties System was formed naturally when water cut through the carboniferous limestone rocks, and it is divided into parts that aid in linking with surrounding caverns. It's nearly impossible to visit all of the cave areas, so start with one.
