Turner's Hill near the heart of the area reaches to 271m above sea level whilst the landscape rises to the 227m high viewpoint of Barr Beacon east of Walsall and, on its southern boundary, to a height of 224m at Wychbury Hill, a northern outlier of the Clent Hills. The area drains to the River Stour to the west, the Penk to the north and eventually to the Tame to the east via numerous tributaries. It is criss-crossed by canals including the Tame Valley Canal, Rushall Canal, Wyrley and Essington Canal, Dudley Canal, Stourbridge Canal, Birmingham Canal, Shropshire Union Canal and Staffordshire and Worcestershire Canal.
