Limekiln Close and East Pit is a 10 hectare Local Nature Reserve (LNR) in Cherry Hinton, on the south-eastern outskirts of Cambridge.

It is managed by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire as Cherry Hinton Chalk Pits.

East Pit is surrounded by steep walls of chalk, and the base is wildflower grassland with areas of scrub.

Flowers include millkwort, harebell, kidney vetch and the rare moon carrot, which is on the British Red List of Threatened Species.

Quarrying ceased 200 years ago in Limekiln Close, and it is now steeply sloping mature woodland with ash and cherry trees.
