The coast from Cow Gap to Beachy Head lighthouse exposes Gault, Upper Greensand and Chalk, with fossils from several parts of the Cretaceous succession. Slipped and changing exposures make provenance important. This demanding tidal shore is distinct from the Holywell–Cow Gap and Birling Gap guides. Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦♦
Birling Gap gives access to Seaford Chalk around the steps and a distinctive chalk dry valley. The Seven Sisters Flint Band and sponge-bearing beds help explain the local fossils. This guide concentrates on the immediate area, rather than treating the shore to Beachy Head or Cuckmere Haven as one safe walking route. Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦
