Twywell Gullet is a 17.1-hectare (42-acre) biological Site of Special Scientific Interest east of Kettering in Northamptonshire.[1][2] It is part of the 54.6 hectare Twywell Hills and Dales nature reserve, which is managed by a partnership of the Woodland Trust and the Rockingham Forest Trust. The site is in turn a small part of the former royal hunting Rockingham Forest.[3]
Twywell Gullet is a former ironstone quarry which has deep cuttings with steeply sloping banks. It has species-rich limestone grassland on the slopes and ponds and scrub in the bottoms. There are a number of uncommon ground nesting bees and wasps, and beetles include the nationally rare ruddy darter.[4] There is a large pond which has a large reedbed and many great crested newts.
Footpaths go through the site but there is no access to some steeply sloping areas.
