Hewitt's Chalk Bank

Hewitt's Chalk Bank is a 4 ha nature reserve north-east of Pratt's Bottom in the London Borough of Bromley. It is managed by the Kent Wildlife Trust.

This former refuse tip has a large mound which is the soil from the excavation of a railway tunnel. Habitats are grassland and scrub, and unusual flora include grass vetchling and dark mullein.

Access is available via a track on the north side of the A21, opposite Sevenoaks Road, though the gate to the site is padlocked.
