A few hours of reseach, and I have found out that fishing appears to be good in Ireland

There seems to be so many possibilties, and it's getting even harder to pick!
Cork seems to be a good choice though, since planes from Denmark all go to Dublin, and from there catching a connection plane to Cork seems to be pretty easy. Also there seems to be a good number of boats going out from Cork, so we could join a tour. Renting a self-drive boats looks interesting, but i believe that requires somewhat more knowledge about the area to be really fun.
Is the fishing good from all coasts in Ireland? Because taking a boat out from Dublin would be even easier, if we considered a weekend trip
Regards and thanks for the help so far!
