Wild swimming in County Down requires caution. Never swim alone, check tide times (especially for coastal spots), and monitor weather conditions via Met Office or local apps.

County Down’s wild swimming spots are primarily coastal, with Strangford Lough offering inland-like sheltered waters. Inland loughs like Castlewellan Lake exist but are less prominent for swimming due to boating or restricted access. Bring a tow float for visibility, especially in open waters. Check water quality updates from DAERA or the European Environment Agency.
