Being a small country, Ireland is fairly easy to get around, and there are a few different ways to do it. Renting a car can be a great way to have the freedom to do what you want and when you want to, but it's important to remember that 1)most cars there have a manual transmission, and 2)you'll be driving on the left side of the road. While this may seem like a small matter, remembering to stay on your side of the road can be tricky, and getting used to shifting with your left arm can take a bit of a toll.

The country's bus system is extensive and can get you to nearly any destination you want, including Northern Ireland. Check their timetables online ahead of time and make sure that your selected routes will mesh, and you should be fine.

The rail system is less extensive than the bus routes and a good deal pricier, but it's tough to beat a train ride through the Irish countryside. If you have the funds to do it, the train is a great way to get across the country.

The less thought of method (since Ireland is so small) is to fly. With Ryanair offering flights from Cork to Dublin for about 10 euro taxes included, it is pretty cheap to get between the major cities if you have the time to do so, and don't mind the antics of Ryanair (you'll understand if you ever fly with them!)

There are lots of choices for getting around, and more than likely you'll find one that suits you best.
