Bundy's Pit

A shallow lake just outside March that's surprisingly good for a quiet afternoon if you've got time to kill between other Cambridgeshire stops. It's the sort of place where you'll actually see what the fens look like - wide, flat, and properly open to the sky. The water's dark and still, ringed by reeds, and birdwatchers do come here because the habitat attracts various wildfowl and waders depending on the season.

Don't expect drama. There's no visitor centre, no facilities to speak of, and the appeal is purely in the landscape itself. It's a working gravel pit that's been allowed to fill with water, so it has that unglamorous, honest feel about it rather than being some manicured attraction. That said, if you're staying at Knightsbridge Caravan and Marina Park just down the road, it makes for a decent walk and a change of scenery - about twenty minutes from the park.

Best for people who actually enjoy Fenland landscape rather than those expecting something dramatic. Kids will get restless quickly unless you're doing it as part of a bigger walking route. Go early morning or late afternoon for the best light and the quietest experience. The flat terrain makes it accessible, though there's nothing to stop you getting your feet wet if you venture off the paths. Worth the detour if you're in the area and the weather's decent - otherwise, keep moving.
