The posted coordinates will take you to an information board on the shores of Mulroy Bay. There you will find the answers to the questions that will lead you to the final cache. Mulroy Bay is a relatively small sea lough that lies between the peninsulas of Rosguill and Fanad in Co Donegal. It is the most convoluted of the marine inlets in northwest Ireland and is approximately 12km long. The entrance to the bay is a narrow embayment leading to a winding entrance channel. This channel varies in width and depth, with three significant narrows only 100–150m across, where the current reaches maxima of 3-5 knots. It opens into the Broad Water, an open shallow sea lough that is generally less than 20m in depth, with many small rocky islands and islets.
The cache is a small tube in a camo outer container and can be found at:
