Ireland South
 Here is OSI's regional map of Southern Ireland. This particular section shows Cork,  Ireland's second largest city after Dublin. You'll need this map if you want to plan a trip from Shannon Airport to quaint towns like Kinsale on Ireland's southern coast.  Scoll down and you can see Cork. These maps are excellent for trip planning. As you can see the red route numbers for the Ireland road system are well marked on the map. But... it's easy to lose track of those numbers when you get in a  large city. Get a city map to get through large cities on your route.
