The physical cache is not at the posted coordinates.
There are multiple stages to this cache; you will need to look carefully to unlock the coordinates to each stage - each one will lead you closer to finding the physical hide.
The stages will take you on a short trail around Kilbaha where you can enjoy beautiful views of the Shannon estuary, learn about some of the historical events that happened here, and maybe enjoy a drink and fill your belly in the local bar!
Each stage will give you the numbers needed for the coordinates of the next stage only - it is not possible to skip stages using previous numbers.
