While you're in Dunbrody there are a good few beautiful spots nearby - Try the "Ring of Hook" drive - The Hook head is a beautiful spot, and is believed to have one of the oldest lighthouses in Europe.
On the way out to the Hook Head, have a look on the right at a beautiful old Mansion - Loftus Hall - the devil is believed to appear here - it's not open to the public - but is always takes my breath away when i see it.
There is also Tintern Abbey that is a monastic abbey, and has lovely walks around it - over a battlement bridge....
There are a few little villages around that are quaint, Fethard-on-sea, Duncannon, Arthurstown, Ballyhack. There are also beautiful little beaches(Duncannon is probably the most popular in the area), but look for directions to Dollar Bay, Booley Bay, Carnivan and Baginbun for lovely less packed beaches.
There's also JFK arboretum, again beautiful walks around the gardens....
Gosh all this makes me want to take a trip
Enjoy, Enjoy, Enjoy!
