Ballylough

Thirty minutes from Castlewellan, this quiet lake sits in rolling countryside that feels properly remote despite being easily accessible by car. The water stretches for roughly half a mile, fringed by reeds and backed by gentle hills that catch the morning light beautifully.

Fishing is the main draw here - pike and perch patrol these waters, making it a decent spot for anglers who prefer solitude to crowds. Walkers will find a rough path around most of the shoreline, though it gets boggy after rain so decent boots are essential. The circuit takes about forty minutes at a gentle pace.

Families might find it a bit lacking unless the kids are keen on wildlife spotting. Herons stalk the shallows most mornings, and you'll often see moorhens and the occasional kingfisher if you're patient. But there's no playground or café, so pack snacks and entertainment.

It's free to visit and open all hours, which makes it handy for an early morning walk or evening fishing session. The lack of facilities means it stays peaceful - you're more likely to encounter sheep than crowds.

For those staying at the holiday parks around Castlewellan, particularly Tollymore Campsite or Windsor Holiday Park, it makes a pleasant detour rather than a main event. Worth combining with a trip to nearby Tollymore Forest Park for a fuller day out.
