Dublin Tourism, the official Regional Tourism Authority for Dublin provides advice to visitors through their website and tourist information centres .

www.visitdublin.com is a great resource for those planning a Dublin trip and here you'll find everything you need to know  before you go with information on accommodation and car hire services, as well as visitor information on a range of topics such as events, transport, tours, museums and galleries. The 'Insiders Guides' are particularly useful and are available in themes such as 'Family Fun' and 'Indulgent Dublin'. You can also purchase the Dublin Pass, the official sightseeing card for Dublin.

The site has a great multimedia section where you can download 'iWalks' for your MP3 player for free. There are lots of themes for these too (Viking & Medieval Dublin, Castles & Cathedrals, Georgian Dublin etc) and they are a great way to discover Dublin at your own pace.

Once you've arrived, you should pop in to one of Dublin Tourism's Tourist Information Offices. There's one at the Airport, one on busy O'Connell Street, one in Dun Loaghaire (where the ferry terminal is) and one in a beautifully renovated church on Suffolk Street. The staff are really helpful and informative and you can pick up brochures, buy your Dublin Pass, book tours, hire cars and reserve accommodation here.

Wicklow (The Garden of Ireland) is only a short drive from Dublin. The website has details about what to see and how to get there.

Wicklow Mountains National Park is another site with plenty of useful information.
