The Northern Ireland Tourist Board (www.discovernorthernireland.com) gives reliable information on all the major tourist attractions in Northern Ireland, such as the Giants' Causeway (a World Heritage Site), the North Coast, and Downpatrick (according to tradition, Saint Patrick's resting place).
Lonely Planet's Ireland also has detailed, county by county, chapters on Northern Ireland, as well as more extensive coverage of places to visit in the Irish Republic.
The Belfast tourist office (see www.gotobelfast.com) is located in the heart of the city in the Belfast Welcome Centre at 47 Donegall Place (tel. 028 + 90246609).
Sites of political interest outside Belfast city centre (east and west Belfast murals, the Peace Lines, Stormont) can easily be visited in Black Taxi tours, while the main city centre landmarks - such as the City Hall, the Albert Clock, Titanic Quarter and the Crown Liquor Saloon - can all comfortably be seen on foot. Queen's University (Conference venue) is located in the south of the city (see www.qub.ac.uk), and is near to a large number of restaurants, bars, parks, and shops on the 'Golden Mile'.
From Belfast it is very easy to visit Dublin and the Irish Republic. The trip to Dublin takes about 2-3 hours by car or by train (the 'Belfast-Dublin Enterprise', which leaves from Belfast Central Station and arrives at Dublin Connolly).
