Lagoon

The Lagoon is a proper water feature just outside Nottingham - the sort of spot locals know about but visitors often miss. It's a lake, straightforward enough, with the kind of appeal that depends entirely on what you're after. Walkers will find it useful; there's a decent loop you can do without much faffing about, and the water itself is pleasant enough to look at, especially on a clear day. The setting is fairly open, which means it can get a bit exposed when the wind picks up.

Families with younger kids might manage an hour here, possibly two if you're keen on feeding ducks or sitting about on the bank. Older children will likely find it a touch dull unless you combine it with nearby walks or cycle routes. It works best as part of a longer day out rather than a destination in its own right.

If you're staying at one of the glamping spots nearby - Peacock Lake, Birdholme, or Gunthorpe Camping are all within five or so miles - it's worth a morning visit before heading elsewhere. The water can be surprisingly moody depending on light and weather, which photographers sometimes find worthwhile. There's no obvious facilities, so bring what you need. Free to visit, no entrance fee that I'm aware of. Best in warmer months when the area feels less bleak. Don't expect anywhere near the appeal of the major parks around Nottinghamshire, but as a quick local walk with water views, it does the job.
