Ok so in Wexford its certainly not underwhelming, merely undersold to tourists. Called the sunny south east for a good reason, there is less rainfall than the rest of the country, which is quite a bit. you have the Irish National Heritage park which is 9000 years of Ireland's past in an outdoor museum! 35 acres of woodlands and wetlands trails. Build a house of wattle, pan for gold or even shoot a Viking bow! Or just relax with a coffee beside the lake while the kids play in the adventure playgrounds. It is an authentic recreation of Ireland’s heritage. Homesteads, places of ritual, burial modes and long forgotten remains will enlighten the casual visitor and interest the scholar. You can also stay the night in a ring fort and cook in a fulacht fia just like they did in the stone ages.
Hook Head which is the oldest working lighthouse in the world with stunning views! Loftus Hall the most haunted house in Ireland and also the staircase was part of three made, one on the titanic, one in the vatican and one in Loftus Hall. Someone already mentioned the Dunbrody Famine ship that takes you on an interactive journey and shows you what life would have been like on what became known as Coffin Ships. Wells House and Gardens is a beautiful old house with falconry, Irelands only (to my knowledge) 3D archery course. The National Opera House, while not 'pretty' as such on the outside is home to one of the worlds largest Opera Festivals and boasts a variety of shows (not just Opera) year round.The National 1798 Rebellion centre in Enniscorthy, The JFK Park and Arboretum, Athaneum in Enniscorthy which is home to a 1916 Rebellion museum, Selskar Abbey built by Henry II of England as penance and is surrounded by the old town walls built by the Normans. Oulart Hill 1798 memorial and battlefield This is just to name a few as remember this is where the Normans first invaded, Wexford is a viking town so there is tonnes of heritage not to mention an abundance of arts, crafts and music. Check out http://www.visitwexford.ie/ and decide for yourselves but certainly dont be narrow viewed in thinking that it is missable. I have travelled extensively all over Ireland, Europe and parts of the US and Wexford has a special feel to it and deep rooted heritage. Just my viewpoint :)
