Lough Conn

Lake Large County Mayo lake renowned for salmon fishing

In County Mayo, Lough Conn draws anglers and birdwatchers to its shallow waters and reed-fringed shores. Visitors come for trout and salmon fishing, boating, lakeside villages and quiet drives along the shoreline.

Lough Conn is a large freshwater lake in County Mayo in the west of Ireland, notable for recreational fishing and open-water birdlife. It is one of the principal lakes in the region and forms part of a wider wetland and lowland landscape.

Angling for brown trout and coarse species is a common activity, and the lake is used for boating and local leisure pursuits. Several small islands and inlets create sheltered bays and varied shoreline habitat.

The lake has long been used by local communities for fishing and navigation and features in local drainage and land-use histories. Management focuses on fisheries, water quality and conservation of wetland habitats.

Lough Conn lies in north County Mayo, northwest Ireland, within easy reach of towns such as Ballina and Crossmolina and around an hour by road from larger regional centres. The surrounding landscape is lowland and bog with agricultural use around the shorelines.

  • Fishing: Well known as a brown-trout fishery and for coarse angling; boat and shore fishing are common uses of the lake.

How to Get to Lough Conn #

Tips for Visiting Lough Conn #

  • Plan early-morning visits for the best light for photography and to catch waterfowl activity; birdwatching is often at its best at dawn along the quieter eastern and northern shores.
  • Avoid weekend crowds by choosing weekdays or the shoulder season outside peak angling competitions - anglers and local outings concentrate at weekends, especially in summer.
  • Be mindful of private shorelines; use designated public access points and car parks around Crossmolina and townland signposted entrances to reach the lake legally and avoid trespass.
