Main image

Lough Neagh is a large freshwater lake in central Northern Ireland and is the largest lake in the British Isles by surface area. It is a prominent natural landmark and an important habitat for wildlife.

The lough supports birdlife, angling and recreational boating along extensive shorelines and shallow bays. Several small islands and reedbeds occur within the lough and its margins provide opportunities for wildlife watching and walking.

The basin was formed by glacial processes and has been used by local communities for fishing and transport for centuries. The lake is drained by the River Bann, which carries water northwards to the coast.

Geographically it sits in central Northern Ireland and is surrounded by rural lowlands and small towns; the lake occupies much of the interior of the island of Ireland’s northern region.

How to Get to Lough Neagh #

Lough Neagh occupies central Northern Ireland and is reached by road from several surrounding towns. By car it is commonly accessed from Belfast and other regional centres via the M2/M1 and connecting A‑roads to towns on the lake shore (for example Antrim, Ballymena and Magherafelt), with parking and short walks to particular shore points. Public buses run from Belfast and nearby towns to settlements on the lough where local roads and footpaths provide access to the water.

Tips for Visiting Lough Neagh #

  • Head to Oxford Island (County Armagh) for the best combination of visitor facilities, waymarked trails and the Lough Neagh Discovery Centre-the reserve is the easiest place to experience the lake's birdlife and viewpoints.
  • If you want boating or waterside villages, plan to visit Toome or other small harbours around the lough; early morning is the best time for birdwatching and quieter waterside views.
