Strangford Lough

Strangford Lough is a large sea lough and inlet on the east coast of County Down in Northern Ireland, notable for its sheltered waters and many islands. It is one of the largest marine inlets in the British Isles and supports important habitats for seabirds, marine life, and coastal ecosystems.

The lough’s sheltered bays, mudflats and islands attract birdlife and marine species and make it a centre for recreational boating, wildlife tours and fishing. Several small ports and villages sit on its shores and it is used for both leisure and commercial activities.

Historically and ecologically important, the lough has designated conservation areas and nature reserves that protect its habitats. It has long been used by local communities for fishing and transport and today supports a mix of settlement, tourism and conservation.

Geographically it lies on Northern Ireland’s east coast, opening into the Irish Sea; the entrance between Portaferry and Strangford marks the seaward mouth and the lough extends inland for several tens of kilometres.

• Tidal currents and wildlife: Home to strong tidal currents and a network of islands and sheltered bays, making it notable for boating, wildlife watching, and strong marine habitats.
• Access: A short vehicle journey from Belfast and within easy reach of Belfast and Strangford towns; a vehicle ferry connects Strangford and Portaferry at the lough's entrance.
