The Antrim coast is one of the most beautiful parts of Ireland, with The Antrim Coast Road taking in some of the best scenery in the country.
The Glens of Antrim offer isolated rugged landscapes, the Giant's Causeway is one of the most striking landscapes on Earth and is a UNESCO World Heritage site, Bushmillls produces legendary whiskey, and Portrush is where Northern Ireland goes to party. It is one of Ireland's most fascinating counties.
Belfast International Airport is situated near the town of Antrim, and is convenient for exploring the region. Ferries from Scotland land at Larne.
Translink operates the public transport system in Antrim.
Standard Northern Irish fare, but if you're lucky enough to catch the Oul Lammas Fair in Ballycastle, be sure to try Yellow Man, a rock hard yellow sweet that is eaten with the aid of a hammer. Make sure your dental insurance is up to date first.
Bushmills, of course. You can take distillery tours, and you'll likely be more merry going out than when you went in.
Stay sensible, don't wander around urban areas at night or make political statements in strange company, and you'll be just fine.
