County Sligo / County Leitrim
Many of the caves of these counties are located on the high limestone plateaux. The limestone is rich in chert, which has greatly influenced cave development with numerous deep potholes but few caves of significant horizontal length.
The most important systems are those above the village of Geevagh in County Sligo, these include Carrowmore caverns and Polliska. The high plateau between Glencar and Glenade and that North East of Glenade are also dotted with many potholes.
Recent guides to the Caves of Geevagh and the northern Dartry hills have been produced by SUI and are available on-line to SUI members on the “Members only” page (available soon).
This area adjoins the Fermanagh / Cavan area and cavers tend to visit it from there using the accommodation and pubs in that area.
