Wigpool Ironstone Mine (grid reference SO654197) is a 34.88-hectare (86.2-acre) biological Site of Special Scientific Interest in Gloucestershire, notified in 1998.

[1][2] The mine is one of a series of Sites of Special Scientific Interest within the Forest of Dean and Wye Valley (Gloucestershire and Monmouthshire).

A ring of iron-ore bearing Carboniferous Limestone in the Forest of Dean has created a series of ancient and more recent mines which provide hibernation sites.

Wigpool Ironstone Mine is a recorded hibernation site for both Lesser and Greater Horseshoe bats.

The entrances to the site are gated and grilled to protect the bats from interference and Natural England reports that all ten of them were checked by the Forest of Dean Caving Conservation and Access Group in September 2011.
