It straddles the Derbyshire and Nottinghamshire county boundaries and is jointly owned by the two county Wildlife Trusts. In spring and summer the reserve's ponds and the wet sections of the canal are a refuge for grass snakes, amphibians and dragonflies. Butterflies and many other insects breed and feed on the wild flowers growing in the grassland. The meadows are best known for their birds. In spring lapwings can be seen performing their impressive aerial displays, while early mornings may offer the best chance of hearing the strange 'drumming' call of breeding snipe. More common breeding birds include the reed buntings with their distinctive black and white heads, and sedge warblers, more camouflaged but twice as noisy in declaring their presence. In spring and autumn the breeding birds are joined by waders, wildfowl and even birds of prey like the hen harrier. Many wildfowl stay for the winter, including a small flock of wigeon, numerous teal and a range of other species.

St John's Church dates to the 19th century and is in the Decorated style. It was built in 1871 as a chapel of ease by Stevens & Robinson for the parish of Langley Mill.

The castle is on private land, having been sold off. English Heritage maintains the ruins...but there's no access to the site other than a footpath, which goes past it.
