THE underground water system in south Galway is a virtually uncharted labyrinth.

In recent years, Mr Kozlowski has set about exploring the vast limestone cave network throughout the region.

The underground waterways run from the Slieve Aughty mountains in the Galway/Clare region and surface just before Kiltartan in the lowlands before going underground through a limestone network towards Kinvara along the coast.

As a result of the underground rivers, the region is prone to widespread flooding.

The cave at Pollonora in Kiltartan, Co Galway is accessed within 50 metres of the rear of a bed and breakfast and is surrounded by trees and shrubbery.

The cave is entirely flooded from the dive entry point to its most explored depths.

An air pocket exists in the middle of it and the ceiling consists of rocks and soil.

The cave connects with others -- known as Polldeelin, Polltoophill, and Pollaloughabo --along a 4km network.

As visibility can often be limited to half a metre or less -- a difficulty which can be increased by disturbing fine silt -- divers often prefer to access the caves during wet weather periods as the natural routes of streams and rivers guide them along their route.
