mainland. It is partially arable, and supports a small population. Islandmagee is a peninsula separating Larne Lough from the North Channel. The valleys of the Bann and Lagan, with the intervening shores of Lough Neagh, form the fertile lowlands. These two rivers, both rising in County Down, are the only ones of importance. The latter flows to Belfast Lough, the former drains Lough Neagh, which is fed by a number of smaller streams. The fisheries of the Bann and of Lough Neagh (especially for salmon and eels) are of value both commercially and to sportsmen, the small town of Toome, at the outflow of the river, being the centre. Immediately below this point lies Lough Beg, the "Small Lake", about lower than Lough Neagh. Transport County Antrim has a number of air, rail and sea links. Air Northern Ireland's main airport, Belfast International Airport, at Aldergrove is in County Antrim. Belfast International shares its runways with 38 Brigade Flying Station Aldergrove, which otherwise has its own facilities. It is the fifth-largest regional air cargo centre in the UK. There are regular services to Great Britain, Europe and North America. The region is also served by George Best Belfast City Airport, a mile east of Belfast city centre on the County Down side of the city, which was renamed in 2006 in honour of footballer George Best. Rail The main Translink Northern Ireland Railways routes are the major line between Belfast, Antrim, Ballymena, Coleraine and Derry, Belfast to Carrickfergus and Larne, the port for Stranraer in Scotland and Coleraine to Portrush. Sea Two of Northern Ireland's main ports are in County Antrim, Larne and Belfast. Ferries sail from Larne Harbour to destinations including Cairnryan in Scotland. The Port of Belfast is Northern Ireland's principal maritime gateway, serving the Northern Ireland economy and increasingly that of the Republic of Ireland. It is a major centre of industry and commerce and has become established as the focus of logistics activity for Northern Ireland. Around two-thirds of Northern Ireland's seaborne trade, and a quarter of that for Ireland as a whole is handled at the port, which receives over 6,000 vessels each year. Population The population of County Antrim was 615,384 according to recent census information, making it the most populous county in Northern Ireland.
