If you are coming to Ireland. Then you'll have to see the real capital, Cork city.
Among Cork's many hidden gems is this free experience with the English Market, grey herons on Grand Parade (Cork's central street).
If you've got an alarm clock and a few pieces of fish. Then you'll be best of friends with these early-risers.
Say hello to Paul from K. O. Connell's fishmongers in the English Market while you are at it. He's another early riser. Though he's rarely up before the herons.
If you have a spare minute. My video/blog on my regular encounters with these aviary bad boys and girls on their fishing expedition in Cork city center is worth a watch IMO...
