Ireland is a large island to the west of Britain. The Irish Republic occupies most of the island, and is confusingly usually called 'Ireland', while a small section in the north, part of the United Kingdom, is called Northern Ireland. The capital of Ireland is Dublin, while Belfast is the capital of Northern Ireland. If you have a hire car in Ireland, you'll soon see it's a largely rural area of well-watered lush green farmland with some rugged low-level mountain regions, especially in the wilder west. Apart from the livelier capitals most attractions are natural; visitors appreciate the lakes, river and coasts, and quiet traditional countryside.
Dublin is the top destination in Ireland, thanks to its combination of sociable atmosphere and cultural heritage. Belfast is also popular for its links to the Titanic. Natural destinations feature highly in Ireland too. For example, in the north, the striking basalt columns of the Giant's Causeway, and the spectacular Cliffs of Moher in the south are major tourist hotspots. The seascapes of Connemara and Cork are great draws for visitors too. And if you have a hire car in Ireland, the famous route to drive is 'The Ring of Kerry' around the most scenic spots along the west coast.
In both Ireland and Northern Ireland traffic drives on the left. Wearing seatbelts is compulsory in the front and back, and drink-drive laws are strictly enforced. The south uses Metric kilometres, the north uses Imperial miles. In the south, the speed limit is 120kph (75mph) on motorways, 100kph (62kph) on other roads, and 50kph (31mph) in towns. In the North, the limits are 112mph (70mph) on motorways and dual carriageways, 96kph (60mph) on single carriageway roads, and 48kph (30mph) in built-up areas. When you drive between the two countries, the border is usually barely discernible - you will not need to stop or show a passport.
