I really think you should consider allocating a few days to Derry (Londonderry- depending on who you talk to) and the Antrim Coast if you want to see the best of Northern Ireland. If you are pressed for time and could not visit both cities, you could completely skip Belfast, in my opinion. Belfast is nice to visit but has less to offer, and is more touristy than the city of Derry. I am from Dublin, and Derry is my favourite city in the island of Ireland. Derry is a gorgeous walled city that is about an hours drive from Belfast, located on the river Bann. It is a lovely city to explore and is steeped in history, also. If you are interested in “the Troubles”(Unionist v. Nationalist conflict) you could easily spend a few hours walking up on the city walls which not only give you a great panoramic view of the city, but let you see peace fences, partisan murals and graffiti. It is a really eye opening experience just strolling around on the walls and really makes history come alive.

Also, I would highly recommend visiting the Antrim Coast with the Giant’s Causeway being a highlight. It is a gorgeous, bizarre rock formation that is well worth a visit. A few minutes further down the coast are the ruins of Dunluce Castle which are also worth a visit.

As for Dublin, there is much to do and and see in the city, but you should consider taking a daytrip to Co. Meath to see Newgrange (ancient burial site older than Stonehenge), or down to Co. Wicklow and explore Powerscourt Waterfall. Also, while in Dublin I highly recommend a visit to the Guinness brewery. Although it is quite cliche and touristy, the view from the sky bar at the end of the tour is one of the best.

Sorry if this was a bit long-winded! Enjoy your visit to the UK and Ireland!
