Hollowell Reservoir

Water and sky merge at this sprawling reservoir just outside Northampton, a proper working landscape that's been quietly pulling in walkers and anglers for decades. Hollowell Reservoir isn't manicured or touristy - it's the real thing, where you'll spot fishermen casting lines and the occasional heron stalking the shallows. The walk around the perimeter takes the better part of two hours if you're in no rush, and the flat terrain means it suits families with younger legs as much as serious ramblers after a morning's fresh air.

The water itself is the main event here. On a decent day the reflections are properly striking, and if you time it right during migration season you might catch glimpses of visiting birds. It's less about dramatic vistas and more about that sense of space and calm you get standing by a large body of water on a quiet afternoon.

Based near Northampton, it works well as a half-day excursion if you're staying at one of the nearby caravan and glamping sites - Lakeview Glamping and Steepleton Lodge Glamping are within three miles. Bring binoculars if you're into birdwatching, though honestly the main draw is just the walk itself and the chance to clear your head. Free to access, no hassle, no queues. It's the sort of place that rewards a low-key approach rather than a rushed tick-box visit.
