Allenvale Lake

The water here is properly still on most days, reflecting the Cambridgeshire sky like glass. Allenvale Lake sits just east of Peterborough, a quiet spot that doesn't get mobbed with tourists the way some nature reserves do. It's a working gravel pit that's been allowed to become something rather lovely - the kind of place where you actually see wildlife rather than just read about it on an interpretation board.

You'll spot herons, the odd kingfisher if you're lucky, and plenty of waterfowl. The walking is gentle and undemanding, which means families with younger kids won't spend the whole time hearing complaints about sore feet. There's no café or facilities to speak of, so bring what you need. A couple of hours is the right amount of time - any longer and you've exhausted what's on offer.

It works well as part of a broader park holiday in the area. Ferry Meadows Caravan and Motorhome Club Campsite is only 2.6 miles away and rates highly, making it straightforward to base yourself there and slip out to the lake for a morning walk. Nene Outdoors, 3.1 miles distant, is another option if you're flexible. The lake feels more genuine than some nature reserves - less manicured, more actual wildlife habitat. Don't expect dramatic vistas or photo opportunities round every corner. Go for peace and a proper dose of Cambridgeshire countryside, and you'll leave satisfied.
