Little Blakenham Pit

Little Blakenham Pit is a 3.4 hectare biological Site of Special Scientific Interest in Little Blakenham in Suffolk.

A 127 metre long tunnel from one of these chalk pits is used by hibernating bats, and it is one of the largest underground roosts known in Britain. Around 450 bats use the tunnel, mainly Daubenton's. Bats also share a lime kiln with a badger sett. The site also has chalk grassland.

The site is private land with no public access.
