Splash doggy

There's a giant inflatable dog standing in a field near Grantham, and yes, it's exactly as daft as it sounds. Splash Doggy is a cheerful, oversized canine that's become something of a roadside oddity in Lincolnshire - the kind of thing that makes you do a double-take as you're driving past, then pull over to see what on earth you're looking at.

It's free to have a look, which is the main appeal. You're not going to spend hours here - five minutes of gawping and photos is about right - but it's the sort of landmark that breaks up a journey nicely or gives kids a quick giggle if you're exploring the area. The novelty is entirely in the absurdity of finding a massive inflatable dog in the Lincolnshire countryside.

If you're staying at Wagtail Country Park just down the road, it's worth a quick detour en route. The park itself is rated well enough, and Splash Doggy makes an amusing bonus if you've got the kids in the car and need a distraction. Don't expect anything elaborate - just pull over, have a look, take the photo, and carry on. It's quirky more than substantial, but that's rather the point. The sort of thing you'll remember precisely because it was completely pointless.
