OK SIM should have got to this earlier. First off I will point you to the
NI Tourist Board website. To be honest the search facility is worse than Toytown's and that is saying something eg search Benone Strand and you will get nought, search Limavady and amongst the options is Benone Strand. It is really the biggest load of shite website that I have ever come across in my lifetime and that is saying something. David Barker, I blame you for having worked for them and the fact you come from Dunboyne in County Meath.
First off I would take the coast road to Carlingford just outside Dundalk. It is in County Louth, the scenery is ok (already two things against it) but the people are great and there are some excellent pubs and nosh plus adventure type stuff if you are that way inclined. Weekends are packed with Northerners and Southerners and quite a few English people and the craic is ninety. Follow the road down to Newry and head for Warrenpoint and then along the coast to Rostrevor. Definitely stop for a beer, any pub will do. Choice then is through the Mournes or down the coast to Newcastle, not much to see unless you pull off the beaten track but just stop and ask and someone will give you a recommendation. Newcastle, nice town but too touristy for my liking, but great views of the Mournes and if you go the coast road on your way in and way out you will come across fishing villages like Kilkeel (great Catholic girls boarding school there, St Louise's) and on the outboard journey places like Killough and Ardglass. Maybe take a trip upto Castlewellan and Silent Valley as a detour and it is silent because you will probably be the only bugger there. Forget going straight to Belfast, as I said head up the coast and finish in Strangford. If history is your stuff head into Downpatrick where the Saint himself is buried and there is a great big house called Castleward with brilliant gardens and such if that takes your fancy. You have no choice but to backtrack to Strangford and go across in the car ferry because it is an experience you will never forget and end up in Portaferry. You could spend a week in the Ards Peninsula alone (that is the wee willy bit sticking out on the right hand side), not the jaw dropping scenery that you can expect in Donegal but you will be pleased to find out that Protestants are quite nice people even those with a Scotch accent and don't worry there are more of them up the NE coast. I used to go to Bangor most weekends when I was younger and had a ball.
Most about Belfast has already been mentioned and you will get as good a welcome in a Shankill Road pub as a Falls Road one as long as you are buying, take the Black taxi tour and depending which denomination you get they will tell you their own version of history. Call into Laverys in town, up near the University, basically a bar for all seasons and all breeds; you will fit in great in the biker section even without the hair. Belfast has brilliant nightlife and if you are on your own, you won't be for long.
By all means do the North coast but stick to the coast and not the main road, some great scenary and hidden gems if you take the coast road out of Cushendun for example. You could do the nine glens of Antrim, which is like a mini Gaeltacht but it would take some time I can tell you. Ballycastle to Portrush you can do the Giant's Causeway and all that jazz and do drop into Bushmills. I might even suggest a detour across country to Ian's homeland, Ballymena, just to hear the accents and somewhere in the hills in between you will find the best poteen makers in Ireland.
Ok by this stage, you have been there six months, you have three children on the way and you have only ventured in from the coast once. But things you might think of to finish up the year are: Poststewart more beautiful and less touristy than Portrush, Benone Strand (seven miles of perfect beach that you can drive on), Magillian Point, just beyond the prison (I was there often usually playing hide and seek with my sons on a Sunday and saw my first ever woman in a bikini) and a ferry to Donegal believe it or not. Derry is a must, and if Derry is a must any Tyrone town is ten times better. I love the Sperrins but in all the times I went there I never met one tourist, similarly Lough Neagh is beautiful to me but there is very little to actually see or do. The pubs are brilliant and if Tyrone win the all Ireland you might just be there when there are people there on Tuesday and Wednesday, every other day is packed normally anyway if the bar is open. You have not touched Armagh yet and Fermanagh is a beautiful county which I cannot do justice without a whole other topic.
There is oodles more and I have only provided a brief tour (in between bouts of vomiting and diarrohea) so I hope that the effort is appreciated. If I had one place to choose to go in Northern Ireland where would it be (apart from home obviously). I think if I was going anywhere it would be the Fermanagh Lakes because there is just so much to see and do and I would stay at
Corick Country House because I have been told it is outstanding and that is where I will be staying on my next visit becaue it is centrally located to hit the Fermanagh lakes and Donegal of which I am also a big fan.
if i can think of anything else i will pop it on for you.
