Ireland is a fantastic destination for anglers, boasting pristine rivers and lakes teeming with fish particularly in the Central and Northwest regions. Lough Sheelin is one of Ireland's top wild brown trout loughs fishing well from late May to September. The Rivers Mourne, Strule and Derg in the Northwest provides excellent salmon fishing. The Strule is a spring/early summer spate river. The Mourne provides excellent fishing from June to early October, with prime conditions during late summer and autumn runs.
