The Lagan Navigation was one of the most successful commercial navigations in Ireland and boasts the only flight of 4 locks (Union Locks) in the Irish waterway network.
The remains of the Lagan Navigations canalised sections is one of the region's best assets as it passes through the cities of Belfast and Lisburn, traverses through rolling countryside and picturesque villages entering Lough Neagh, the largest freshwater lake in the British Isles.
From Belfast to Lough Neagh the Lagan Navigation travels East to West, 27 miles with 27 locks, 20 road bridges, 12 footbridges and 1 Railway Bridge. It passes through four Local Government areas - Belfast, Castlereagh, Lisburn, Craigavon and three Counties Antrim, Down and Armagh.
It is the principle objective of the Lagan Canal Trust to re open the Lagan Navigation from Belfast Harbour to Lough Neagh.
