There are several major, long-distance ridgeways that stand up to the test. The Jurassic Way follows the limestone uplands diagonally across England from the Cotswolds to the Yorkshire Wolds or, more specifically, from Bath to Rudston, with the last stretch to the north of the Humber on chalk (Figure 35). Another route runs parallel to it but stays on the chalk outcrop. This starts in Wiltshire and Berkshire as the Ridgeway and continues along the Chilterns and East Anglian Heights as the Icknield Way; in effect it connects Avebury and Stonehenge with Grime’s Graves and the Wash.
