The main access points when it comes to getting into Leinster are by road, sea and air. Traditionally Leinster has both been the most developed area in Ireland and the most populous area in Ireland. As a result the road infrastructure in Leinster is very good as it radiates out from Dublin.
While there are other airports in Leinster which do cater for international flights, (Baldonnel Casement Aerodrome and Weston Executive Airport ), the only International airport is Dublin Airport  (DUB). In 2006 over 22m passengers passed through Dublin Airport marking the 22nd year of consecutive passenger growth figures. Dublin Airport is not the 10th busiest airport in Europe and undergoing significant upgrades to meet future passenger number increases.
While the rail services in Ireland are not at the level of other European countries, things are improving in terms of station upgrades, investment in rolling stock and the amount of trains run daily. In Leinster there are four main lines operated daily by Irish Rail :
Travelling by car around the East Cast and Midlands of Ireland is not the arduous task that it was even five years ago. The road infrastructure is the subject of continuous improvement as many of the main arteries connecting Dublin to the rest of Ireland are upgraded to motorway standard.
The road network in Ireland radiates outwards from Dublin City and the M50 ring road from the N1 to Belfast to the N11 to Wexford.
Car Rental in the East Coast and Midlands area is mainly confined to Dublin Airport  and Dublin City although some car rental companies have locations at Dun Laoghaire Port and Rosslare Europort. While all car rental companies in Ireland have rental desks in the arrivals hall of Dublin Airport, the list of car rental companies with inner city locations is far less. Some of the car rental companies will advertise city centre locations, but these locations are mostly only drop-offs for which an additional charge will added.
AVIS car rental have a location in Mullingar, County Westmeath.
The locations are accessible by the DART which is a regular commuter train service covering most of the coastline north and south of Dublin.

Fairyhouse Races Ratoath Meath - The first meeting held at Fairyhouse was in 1848 when the Ward Union hunt held their point-to-point at this venue. From these small beginnings Fairyhouse quickly established itself as one of Ireland's premier racecourses. In 1870 the Irish Grand National was run for the first time and the winner was ‘Sir Robert Peel'. The Grand National quickly became Ireland's most valuable and prestigious steeplechase and each success has its own rich tale, none more amazing than the win in 1929 of a six year old mare ‘Alike', owned and ridden by 5'4” Frank Wise who was missing three fingers and who rode with a wooden leg. Fairyhouse has always been one of the finest and fairest racecourses and continues to attract the leading horses both on the flat and over jumps. Arkle, Desert Orchid, Flying Bolt, Captain Christy, Prince Regent, Persian War, L'escargot and more recently Istabraq, Bobbyjo, Florida Pearl and Limestone Lad are just some of the legendary greats that have graced the almost 2 mile circuit.
