The Knockmealdown range of mountains was formed about 300 million years ago. The final shaping took place much more recently during the last Ice Age, which started 1 million years ago and ended 10000 years ago. The tops of the mountains were too high to be covered by the ice sheets which covered the lowlands, but they had their own glaciers which carved out corries. The protruding rocks which can be seen are of the Old Red Sandstone family, particularly on Knockmealdown Mountain itself.
The range is cut in two by the Vee Gap, through which the Clogheen to Lismore and Cappoquin road passes. At the Waterford end lies the Bay Lough carpark, and the cache is placed on the Waterford side of the border although the carpark is in Tipperary. Please keep the geodog on a lead as several hundred mountain sheep graze this area. The cache is placed across from, and between, the oratory and statue. As you stand infront of the oratory,you are at the base of Knocknalougha and facing Sugarloaf Hill.
After finding the cache, a short 10 minute stroll brings you to the shores of Bay Lough. A longer 2 hour walk takes you to the summit of Sugarloaf Hill and onward to Knockmealdown, and back again.
