Wormleighton Reservoir

The water is what draws you in first - a broad expanse of it stretching across low Warwickshire countryside, ringed by trees and surprisingly peaceful given how close Oxford is. Wormleighton Reservoir is a proper working water supply, but that hasn't stopped it becoming one of the area's better nature spots. You'll find yourself walking the perimeter paths with binoculars out, watching for overwintering wildfowl and the occasional scarce passage migrant. Birdwatchers will want to linger, though families with young kids might find an hour's circuit enough before everyone gets restless.

The paths are accessible enough for most abilities - flat, well-trodden, nothing demanding - which makes it a decent leg-stretcher between longer walks. Bring a camera if you're into landscape photography; the light on the water mid-afternoon is genuinely worth the stop. There's a certain honesty to it all: no visitor centre fuss, no entry fee hassle, just a reservoir doing its job while people quietly get on with enjoying it.

If you're based at Coleman's Hill Campsite or Hill Farm Glamping nearby, this slots neatly into a morning's wandering before lunch. It's the sort of place to go when you want a gentle break from the main attractions without driving miles. Not dramatic, not Instagram-famous, but genuinely worth half your afternoon if you're in the area and enjoy open water and birds. Winter and spring are best for birdlife, though it's pleasant enough any time the weather cooperates.
