Upper Potterswall Reservoir

The water here sits surprisingly peaceful given how close you are to Antrim town. Upper Potterswall Reservoir isn't flashy - it's just a proper working water supply that happens to make for a decent afternoon out if you're staying nearby. The walk around the perimeter is gentle, nothing demanding, and you get decent views across the water towards the surrounding countryside. Birdwatchers will want to bring binoculars; it's one of those places where you actually spot things rather than just hoping you might.

It's free to visit and takes a couple of hours if you do the full circuit at a leisurely pace. Families with younger kids manage it fine, though there's not much to do once you've walked the loop - no cafe, no playground, just the water and the air. Go when it's not raining sideways, basically.

For those staying at Blair's Castlewood or Six Mile Water caravan parks just down the road, this fills a gap nicely on a day when you want to get out but aren't up for anything ambitious. It's the sort of place that works better as part of a wider ramble around Antrim rather than a destination in itself. Nothing wrong with that - sometimes a quiet walk is exactly what you need.
